Located in the northeastern portion of the Denver metro area, just minutes from downtown Denver and Denver International Airport, Commerce City is adjacent to six major highways, two railroads and two new commuter rail lines.

Air

Commerce City residents and businesses have direct access to Denver International Airport – the fifth-busiest airport in the country and 20th-busiest in the world.

Road

The following major highways provide easy access to and from the city:

• Interstate 70
• Interstate 270
• Interstate 76
• US Highway 85
• CO Highway 2
• E-470

The Colorado Department of Transportation (CDOT) maintains interstates and Highway 85. The E-470 Highway Authority operates the toll road system. Commerce City maintains Highway 2 and local city streets and works with both agencies, as well as Adams County, as needed.

Traffic Counts

The city conducts regular traffic counts on major roads throughout the city. Most locations are counted on a biannual basis to identify trends and help the city engineer improve traffic flow.

Traffic Calming

Traffic calming can include, but is not limited to, the reduction of speed for motorists and increasing safety and/or reduction of traffic accidents at particular locations. Requests for traffic calming can be initiated by submitting a ticket through AccessC3. Please provide the nature of the traffic calming request, including the times and locations of the perceived problem. After a request is submitted, data necessary to determine the nature and severity of the issue will be collected for a minimum of 48 hours.

Bus

A number of Regional Transportation District (RTD) bus routes serve the city and provide residents with public transit connections to rail service, the airport and other communities throughout metro Denver.

• Local bus routes: 40, 48, 72, 88, 120
• Regional bus routes: 104X, 145X, RX/RC
• SkyRide service to DIA: AA

Visit RTD-Denver.com or call 303-299-6000 for more information on routes, schedules and fares.

Note: The route 62 bus that formerly serviced the southern part of the city (along E. 60th Ave. between Vasquez Boulevard and the Civic Center/Dick's Sporting Goods Park) was discontinued in January 2020. Grant funding for route 62 expired on Dec. 31, 2019 and the route was canceled due to low ridership.

Rail

Commerce City residents can access commuter rail service from two RTD lines traveling through or near the city, and two major freight lines also traverse the city.

North Metro Rail Line (N Line)

The RTD N Line opened in September 2020. From the Commerce City-72nd Avenue Station (entrance located at Colorado Boulevard and E. 70th Avenue), residents can ride south to reach Denver Union Station in about 12 minutes or travel north to Eastlake-124th Station in Thornton in roughly 15 minutes.

A Line - Downtown Denver to DIA

The RTD A-Line runs just south and east of Commerce City between Denver Union Station and the airport. The nearest rail stops to Commerce City include the 40th and Colorado Station (accessible via the Route 40 bus) and Central Park Station (accessible via the Route 88 bus).

Freight Rail Lines

The Burlington Northern Santa Fe (BNSF) Railway and Union Pacific Railroad both travel through the length of the city. Commerce City was the first in the state to take advantage of federal regulations allowing for quiet zones at railroad and roadway crossings. Since 2008, the city has installed four zones to eliminate traveling trains from blowing their horns in residential areas.

With so much rail activity in the city, trains are often longer than the distance between roads and can block busy intersections. By reporting these issues directly to the railroad company, residents can alert them of frequent trouble spots and help resolve train-related traffic problems in the city.

• BNSF: 800-832-5452, option 3
• Union Pacific: 402-544-5000
