Transportation throughout the Region

Eagle County

Eagle County has 60 miles of interstate highway; 34 miles of interstate with a 75 mph speed limit. Major highways include I-70, Highway 6, and Highway 82.

Grand County

U.S. Highway 40 & State Highways 9 and 34 are the major roadways through Grand County. At the junction of State Highway 9 (Highway 9) and US Highway 40 (US 40) is the Town of Kremmling. East of Kremmling, US 40 (Colorado River Headwaters Scenic Byway) parallels the Colorado River approximately 14 miles upstream through Byers Canyon and into the Town of Hot Sulphur Springs. This river corridor east of Kremmling is characterized by abundant open lands, primarily used for agriculture and recreation. South of Parshall, County Road 3 crosses the Colorado River near the Kemp/Breeze State Wildlife Area, and continues past Williams Fork Reservoir and up and over Ute Pass and intersecting State Highway 9 in Summit County.

Heading north of Kremmling, US 40 continues past the intersection of State Highway 134 and Wolford Mountain Reservoir, a Colorado River Water Conservation District project, generally following the Muddy Creek drainage north to Rabbit Ears Pass and eventually into Routt County and the City of Steamboat Springs. State Highway 134 intersects US 40 and heads west past “Old Park” and over Gore Pass to Toponas in Routt County. State Highway 9 heads south out of Kremmling and into Summit County along a scenic corridor, adjacent to the Blue River. Just south of Kremmling, the Trough Road (County Road 1), also designated as a Colorado River Headwaters Scenic Byway, branches off of Highway 9 proceeding generally southwest toward State Bridge in Eagle County. Right before the county line (at Sheephorn Creek), there is a junction with County Road 11 that connects to the small railroad community of Radium on the Colorado River. This area adjacent to the Trough Road is known as the Upper Colorado River and is a popular rafting and fishing destination. U.S. Highway 40 branches off from I-70 and climbs to an elevation of 11,307 feet over Berthoud Pass and the Continental Divide to serve as the southeast gateway into Grand County.

Being located only 45 minutes west of the Denver metro area, improvements to U.S. 40 over the last several years has provided easy access to Grand County for tourists, skiers, second-homeowners and residents. Once over the pass, US 40 descends into the town of Winter Park and past the Mary Jane and Winter Park Resort ski area entrances. US 40 provides access to the Fraser Valley and serves as a main street to the town centers of Winter Park and Fraser, both of which provide resort tourism and seasonal services tempered by the historic influence of the railroad and the Moffat Tunnel, particularly in Fraser. US 40 continues north of Fraser, through Tabernash, heading toward Granby. US 40 enters the North Subarea at the top of Red Dirt Hill, near the entrance of YMCA of the Rockies / Snow Mountain Ranch. From here US 40 precedes north and into the Town of Granby. On the west of Granby, State Highway 34 intersects US 40 and heads north to Grand Lake and is designated as the Colorado River Headwaters Scenic Byway (Scenic Byway). US 40 and the Scenic Byway continues west past Windy Gap and through the agricultural valley along the Colorado River into the historic town of Hot Sulphur Springs. At Windy Gap, State Highway 125 intersects US 40 and continues north, up and over Willow Creek Pass to Rand and Walden in Jackson County.

Jackson County

The road network that serves Jackson County includes Roads 12E and 36, Colorado State Highway 125 and State Highway 14. The municipal road network includes a combination of paved streets, as well as improved, unimproved, and “paper” roads. Paper trails are historical road easements that have not been developed by the County. Colorado State Highway 125 extends south from the Colorado/Wyoming border to its intersection with U.S. Highway 40 west of Granby.  The Colorado Department of Transportation classifies this roadway as a minor arterial. The highway segment through the Town of Walden is, a two-lane, paved highway that bisects the east and west sides of the community. Traffic Volumes and Highway Capacity - In 2007, available vehicular traffic data from the Colorado Department of Transportation reveals that average annual daily traffic volumes in the vicinity of Walden ranged between 1,500 vehicles at the intersection of State Highway 125 and State Highway 14 West to 3,600 vehicles per day at the intersection of State Highway 125 and Fifth Street (Colorado Department of Transportation, 2008).

In 2007, about 90 percent of all vehicular traffic in the vicinity of Walden represented passenger automobiles, including light trucks. The remaining traffic was derived from larger trucks, e.g. semi-trucks and trailers. By the year 2035, the Colorado Department of Transportation forecasts that future vehicular traffic volumes in the vicinity of Walden will range between 3,000 and 5,000 vehicles per day. When these volumes are correlated with available highway capacity, no traffic congestion is expected to occur along the State Highway 125 corridor between 2008 and 2035 (Colorado Department of Transportation, 2008). Highway Surface Condition - The Colorado Department of Transportation periodically rates the condition of state highway surfaces via its pavement management system. In 2005, CDOT rated the surface condition of State Highway 125 as “poor”. This rating indicates that the highway surface has a remaining surface life of less than six years (Colorado Department of Transportation, 2008). This rating likely influenced the decision to re-pave a 14-mile segment north of the State Highway 125/U.S. Highway 40 intersection. Highway Bridge Condition - The Colorado Department of Transportation also monitors and rates the condition of state highway bridges.

CDOT’s bridge management system considers the structural condition and functional integrity of each bridge on the state highway system and assigns a sufficiency rating that ranges from 0 to 100. CDOT determined that the Michigan River Bridge that crosses State Highway 125 is functionally obsolete” and eligible for funding to replace the bridge. The Michigan River Bridge was also assigned a sufficiency rating of 55 which indicates that the bridge is also eligible for rehabilitation. The policy of CDOT is to make bridge replacements in conjunction with other road upgrades (Colorado Department of Transportation, 2008) Planned Highway Improvements - The 2035 Regional Transportation Plan recognizes that the State Highway 125 corridor is important to sustain agriculture, tourism, and forest management. CDOT’s planning objectives focus primarily upon continued efforts to improve public safety. The Plan identifies various highway improvement needs such as improving highway geometrics, adding road shoulders, and improving roadway surfaces, as well as bridge repairs and replacement (Colorado Department of Transportation, 2008). However, the Plan does not outline a schedule for future improvements to State Highway 125. In this context, it is important that this municipal master plan incorporate strategies to encourage future implementation of the highway improvements outlined in the Regional Transportation Plan for northwest Colorado.

Pitkin County

State Highway 82 is an 85.29 mile (137.26 km) long state highway that provides the principal transportation artery of Pitkin County and the Roaring Fork Valley. The Roaring Fork Valley is defined by the valley of the Roaring Fork River and its tributaries, including the Crystal and Fryingpan Rivers, and includes the communities of Aspen, Snowmass Village, and Basalt in Pitkin County, and the neighboring communities of Glenwood Springs and Carbondale in Garfield County. Highway 82 runs from Interstate 70 at Glenwood Springs southeast past Carbondale and Basalt and through the City of Aspen. Southeast of Aspen it climbs to 12,095 ft (3,687 m) on a 6% grade at Independence Pass (open late May–October). At its northwestern end it furnishes the principal vehicle access between most of Colorado and the City of Aspen and Snowmass Village and the world-class ski resorts located in these communities. Recently widened to four-lanes along the 50 mile (80 km) section between Glenwood Springs and Aspen, it is heavily used commuting route for day workers between bedroom communities in the lower valley and the resort community of Aspen. The highway roughly follows the Roaring Fork River along its entire route, offering scenic views of Mount Sopris in the lower end of the valley. The Roaring Fork Transit Authority (RFTA) provides well-used public transportation along the highway between Glenwood Springs and Aspen.

Summit County

Interstate 70 (I-70) runs east to west, bisecting the County and moving thousands of vehicles on a daily basis through the County. In addition, state highways 6 and 9 provide major movement arterials connecting the communities of Keystone, Dillon, Silverthorne, Frisco, and Breckenridge. County roads such as the Swan Mountain Road and Dillon Dam Road provide additional critical links between the County’s urban areas. Other county and town roads serve as collectors providing access to local roads. The mountainous geography of the County precludes most possibilities for alternative routes between major urban areas. Therefore, the existing system of roads will continue to serve as the primary routes in the County.

Public Transit

Eagle County

ECO Transit provides bus service 21.5 hours per day, 7 days per week, and 365 days per year throughout the Eagle Valley and beyond. ECO Transit maintains a fleet of 34 buses.

The Eagle County Transit Authority currently provides service between Dotsero, Gypsum, Eagle County Airport, Eagle, Avon, and Vail. The existing bus transportation services offered in Eagle County include the Eagle County Regional Transportation Authority, Roaring Fork Regional Transportation Authority, Town of Avon Transit System, and the Town of Vail Transit System. Eagle County Regional Transportation Authority and Roaring Fork Transportation Authority both offer extensive regional service. The town transit systems serve locals and visitors within town boundaries and act as feeders to the regional systems. The search is on-going to find suitable locations for public transit facilities, transit hubs and park- and-ride locations.

Grand County

For years, the community has been served by “The Lift,” a bus system that provides transportation from the ski area through Winter Park and Fraser, with some routes as far as Granby. “The Lift” is funded by the ski area and the Towns of Fraser and Winter Park. Intrawest contracts with First Transit (a private transit management company) to operate the service. This transit system has posed challenges in the past, and may be subject to restructuring as the current operator of the ski area, Intrawest, reviews its operations. The County recognizes the need for a community transit system as a component of a means of transporting guests to the ski area and other destinations and transporting the workforce to the county after working hours. Funding challenges and lack of ridership could hinder the viability of a sustainable year-round public transportation system to serve Grand County. The County does currently have Greyhound bus service. The Grand County Council on Aging operates 6 vehicles (3 minivans & 3 minibuses) that provides some scheduled trips and some "demand response" trips for seniors for medical appointments, nutrition sites, grocery shopping, recreational and social activities.

Jackson County

The Jackson County Council on Aging operates an 11-passenger van to provide a demand response service for County residents who are 60 years and older, and persons with disabilities. This service provides transportation to medical appointments and other services that are available in Granby, Kremmling, and Steamboat Springs, Colorado; as well as Laramie and Cheyenne, Wyoming. Aside from this service, there are no regional private or public transportation services in Jackson County that provide any bus transportation service to nearby communities that provide some medical, professional and technical services to other Walden residents. The lack of this service also impacts the ability of the County’s primary working age population to seek employment opportunities in communities such as Steamboat Springs, Granby and Laramie without relocating and moving away from the County. In order to sustain the social and economic viability of Jackson County, expanded public transportation alternatives are needed to provide greater connectivity to Steamboat Springs, Granby, and Laramie. This is particularly true if energy prices remain at higher levels and various medical, professional and technical services remain unavailable in the community. In this regard, the County should participate in any regional coalition of public agencies, non-profit organizations, and private companies that may be organized in the future to implement regional public transportation solutions in northwest Colorado.

Pitkin County

The Roaring Fork Transportation Authority has been in operation since 1983, and functions as a Regional Transportation Authority. The RTA includes the communities of Aspen, Snowmass Village, Pitkin County, Basalt, a portion of Eagle County, Carbondale, Glenwood Springs and our newest member New Castle. RFTA provides commuter bus service from Aspen to Glenwood Springs (Roaring Fork Valley), Glenwood to Rifle (Hogback), intra city service in Aspen and Glenwood Springs, ski shuttle service to the four Aspen Skiing Company ski areas, Maroon Bells Guided Bus Tours, and a variety of other seasonal services. RFTA currently operates a fleet of over 82 vehicles and carries over 4.1 million passengers per year. RFTA uses Biodiesel fuel in all of its fleet of diesel power vehicles including its hybrid buses, and ethanol in its gasoline vehicles. RFTA's Regional Bus Rapid Transit (BRT) Project -BRT is a rubber tire transit service that combines stations, vehicles, running ways, a flexible operating plan, and technology into a high quality, customer focused service that is fast, reliable, comfortable and cost efficient. The new BRT service is called VelociRFTA. The goal of the VelociRFTA BRT project is to improve RFTA's operations and facilities to be faster, more convenient, and more comfortable. BRT combines the flexibility and cost savings of buses with the efficiency, speed, reliability, and amenities of rail. RFTA is implementing the first phase of VelociRFTA which is anticipated to be in place by 2013.

Summit County

The Summit Stage provides free bus service between all major urban areas of the County. Other bus systems are operated by the Town of Breckenridge and the resorts of Keystone, Copper Mountain, and Breckenridge. Utilizing one or a combination of these transit systems, it is possible for persons to travel between the urban areas of the County. Because each of these systems is run independently, there could be a better coordination between the different systems to integrate service and increase efficiencies. Moreover, the local school district has an entire fleet of buses that are generally not in operation on weekends or during part of each weekday. Cooperation with the school district could increase opportunities as well.

Airports and Air Service

Eagle County Regional Airport

The Eagle County Regional Airport is located south of Interstate 70 just off Highway 6 between the towns of Eagle and Gypsum, Colorado. The airport was dedicated on Sept. 14, 1947 and provided general aviation services for many years. In 1989, there were 277 commercial passengers. In 1996, a $9 million, 36,000 sq. ft. passenger terminal was unveiled, accommodating a 73 percent increase in passengers during that season. The demands on the new terminal prompted an additional 30,000 sq. ft. expansion in 2001, to accommodate the growing popularity of commercial air service to EGE. The airport is served by four major airlines: American, Continental, Delta, and United, with non-stop service to 13 hub airports in 12 major cities: Atlanta, Chicago, Cincinnati, Dallas, Denver, Detroit, Houston, Los Angeles, Miami, Minneapolis, New York (JFK and La Guardia), and Newark. Since 1994 annual airport operations have increased 214 percent and since 1993 annual passenger enplanements have increased 47 fold. This growth has earned the Eagle County Regional Airport the ranking of third busiest airport in Colorado based on annual airline passenger traffic numbers. In 2008, a study commissioned by the Colorado Department of Transportation Aeronautics Division found that the total quantifiable impact on the local economy from the airport in that year totaled $982,170,400. In addition, the Eagle County Regional Airport created 10,467 jobs, paying $293,886,700 in wages. Runway: 9.000 feet long x 150 feet wide

Aspen / Pitkin County Airport

The airport is served by two airlines operating daily, year-round scheduled service. The airlines serving the airport are United Express (operated by SkyWest Airlines) and Republic Airlines (operated by Frontier Airlines). The airlines occupy ticket counters, baggage facilities and offices at the airport for full services to the flying public. The runway at Aspen-Pitkin County Airport was lengthened and widened in 1983 to its present size, 7,006 feet long by 100 feet wide. The entire terminal area was redeveloped in 1986 and 1987, which included new vehicular access roadways and the expansion of the terminal to its present size of 37,500 square feet. In 1999, the aircraft-parking area was again expanded to allow for more aircraft parking. Expansion Plans: Aspen/Pitkin County Airport - Due to the current length of the runway, many flights leaving Aspen cannot takeoff with full passenger loads. Therefore, the airport is extending the runway toward Buttermilk by 1,000 feet. This extension will allow existing flights to accommodate more passengers, will result in greater efficiency and passenger convenience and will NOT result in larger jets flying into/out of the airport, which is prohibited by Pitkin County regulations. The Federal Aviation Administration will cover approximately 95% of costs. Construction is scheduled to begin in 2011. Runway: 7,006 feet long x 100 feet wide

Granby Airport

Located in open terrain atop the Granby Mesa in Granby, Colorado. The airport is an easy-in, easy out mountain airfield that has a County-plowed runway in winter and no fees. The airport accommodates up to medium twin turbo-props and light business jets (ARC B-II) The field elevation is 8203 MSL. The runway is 5,000 x 75 feet. Currently, 30 aircraft are hangared at Granby (GNB), in a combination of privately-owned and county-owned hangars. At this time, all of the existing hangars are full; however, Grand County (the airport sponsor) is open to contact by individuals or companies desiring to build hangars at GNB. Runway: 5,000 feet long x 75 feet wide Mc Elroy Airfield-20V (Kremmling, Colorado) – located in the Town of Kremmling and owned and maintained by Grand County. McElroy Airfield has two runways, both 5,540 x 75 feet long. The capacity of both runways is 46,000 pounds for single wheel gear and 68.000 pounds for double wheel gear. Additional services supported by the airport include air freight, air ambulance, crop dusting, charter flights and flight instruction. There are currently 15 T-Hangars and 4 box hangars located on the airport.
