Map of Denver prepared by Matt Strieby - August 2008

The largest city in Colorado and the state capital is Denver, the Mile High City. Situated at 5,280 feet above sea level, Denver rests at the foot of the impressive Front Range of the Rocky Mountains, and at the crest of a gradual rise in elevation from east to west across the Great Plains. A hub of commercial activity for not only Colorado but all surrounding states, Denver is a transportation center, with three major highways, a major airport, and a variety of railroads serving the city.

Denver is also the gateway to the ski resorts in the mountains, including world-class facilities in Vail, Aspen, Steamboat Springs, Winter Park, Breckinridge, Loveland Pass and many other mountain locations. Finally, with Downtown redevelopment in the 2000s and an economic boom largely due to telecommunications, Denver is an attractive environment for finding work. The city boasts franchises in all five major league sports leagues, with world class venues in and around Downtown.

Interstates

Interstate 25 – Valley Highway

Originally built as a new alignment for U.S. 87, the Valley Highway initially opened in 1958 from Evans Avenue (Exit 203) north to 48th Avenue (now I-70 / Exit 213), and throughout the Denver area by 1963. An extremely busy route with traffic counts well above 200,000 vehicles per day, Interstate 25 both serves freight travel south to New Mexico and north to Wyoming, as well as commuter traffic north to Fort Collins and south to Castle Rock and Colorado Springs. The T-Rex mega project rebuilt the Valley Highway to modern standards over a six year period from Arapahoe County north to the Broadway viaduct at Washington Park West in Denver. The $1.67-billion project was completed in 2006.

Additional work replaced the Broadway viaduct through Baker, rebuilt the interchanges with U.S. 85 (Santa Fe Drive) and U.S. 6 (Sixth Avenue) and added Express Lanes north from 20th Street at Highland in Denver to SH 128 (120th Avenue) at Westminster and Northglenn. RTD light rail parallels the freeway southward from Denver to Centennial and Lone Tree in Douglas County as well.

Interstate 70

Interstate 70 runs across the northern periphery of Denver, from Regis to Stapleton and Montbello. The freeway connects the city with Aurora to the east and Arvada, Wheat Ridge and Golden to the west. The oldest section of I-70 is the elevated viaduct through Elyria Swansea in Denver, having opened to traffic in 1964. The Central 70 project reconstructs ten miles of the freeway east from Interstate 25 to Exit 283 / Chambers Road. This includes lowering the highway below grade, building a lid at Elyria Swansea and adding tolled Express Lanes. The five year rebuild started in 2018.

Interstate 76

Interstate 76 branches north from I-70 between Arvada and Wheat Ridge to Twin Lakes and North Washington in unincorporated Adams County. The freeway continues northeast to Welby, Commerce City, Derby and Brighton. Regionally I-76 joins the Denver metropolitan area with Interstate 80 across southern Nebraska.

Interstate 225

Guides:

Interstate 225

A belt route encircling southeast Denver through Aurora, Interstate 225 links I-25 at Hampden South with I-70 by the Gateway – Green Valley Ranch community. The freeway joins the south suburbs of Douglas County, and Denver Tech Center with Denver International Airport (DEN) via connections with Pena Boulevard north from near the north end. RTD light rail accompanies the six to eight lane freeway throughout Aurora as well.

Interstate 270

Guides:

Interstate 270

Interstate 270 winds northwest along side Sand Creek from Stapleton in northeast Denver through industrial areas of Commerce City. The urban loop provides a direct route linking I-70 and the Denver International Airport (DEN) area with U.S. 36 (Denver-Boulder Turnpike) northwest to Westminster, Broomfield and other suburbs.

Prior to 2003, Interstate 270 ended at I-76 from the southeast, with the connection west to I-25 and the Denver-Boulder Turnpike signed as Future I-270. The route doubles as unsigned U.S. 36, which uses I-270 to continue east along I-70 through east Aurora.

Toll Highways

Colorado Highway E-470

E-470 provides a bypass around the east side of the Denver metropolitan area. The tollway originates in Douglas County from Exit 194 of Interstate 25, opposite C-470. The beltway encircles Aurora northeast to Adams County and Denver International Airport (DEN). Turning northwest, E-470 travels through Commerce City and north Thornton to end at Exit 228 of I-25 and the Northwest Parkway.

The E-470 beltway opened in stages from June 1991 to January 2003. Full interchanges at I-70 in east Aurora and I-76 on the Brighton and Commerce City line are incomplete, or require at-grade connections. The bypass switched to all electronic tolling (AET) in 2009.

Northwest Parkway

Guides:

Northwest Parkway

Completed in November 2003, the 8.05 mile long Northwest Parkway represents a portion of the northwest quadrant of the Denver beltway system. Designated by CDOT as Route 470N, the toll road arcs west from Interstate 25 and E-470 across Broomfield to Via Varra and 96th Street. An at-grade portion of the parkway continues south from there to U.S. 36 (Denver-Boulder Turnpike) and Interlocken Loop. Future work will extend the road southwest as Jefferson Parkway to SH 93 in Golden.

U.S. Highways

U.S. 6

Guides:

U.S. 6

U.S. 6, the nearly transcontinental route coming into Denver via Clear Creek Canyon, crosses paths with Interstate 70 at Golden, then passes through Lakewood and west Denver as the 6th Avenue freeway. From the eastern terminus of the 6th Avenue freeway, U.S. 6 takes a convoluted route through Denver. First it turns north on I-25, then heads east on I-70 to Vasquez Boulevard through Elyra Swansea. The route emerges from the freeway along side U.S. 85 through Commerce City, where the pair briefly join SH 2 before separating at Colorado Boulevard. SH 2 represents the historic alignment of U.S. 6 northeast to Brighton, while U.S. 6 combines with Interstate 76 east to Fort Morgan.

U.S. 36 – Denver-Boulder Turnpike

U.S. 36, which was extended west to overtake the Denver-Boulder Turnpike, enters the metropolitan area south from Lyons. The commuter freeway includes a tolled Express Lane in each direction as it angles southeast from Boulder through Louisville, Superior, Broomfield and Westminster. Once U.S. 36 meets I-25, it becomes a hidden route, overlaying Interstate 270 southeast through Commerce City, and I-70 through northeast Denver and Aurora. The US highway branches east from the Interstate system beyond Bennett, taking an independent route across the plains of Eastern Colorado.

Historically U.S. 36 ran concurrent with U.S. 40 and U.S. 287 along Colfax Avenue through Aurora and Downtown Denver.

U.S. 40

Guides:

U.S. 40 – Colfax Avenue

U.S. 40 follows Business Loop I-70 (Colfax Avenue) east from Golden through Lakewood, Downtown Denver, and east Aurora. The two routes are consistently signed on their shared alignment, which travels along a slow moving commercial boulevard or arterial throughout most of the Denver metro area.

U.S. 85

Guides:

U.S. 85 – Santa Fe Dr, Vasquez Blvd, Brighton Blvd

U.S. 85 mirrors the course of Plum Creek north along Santa Fe Drive from Castle Rock and the Douglas County suburbs to Chatfield Lake and the city of Littleton. Santa Fe Drive shifts eastward and parallels the South Platte River to Englewood and Sheridan, entering the city of Denver at Overland. U.S. 85 combines with Interstate 25 at Baker, following Valley Highway north to I-70 at Globeville, and I-70 east to Vasquez Boulevard and U.S. 6 at Elyria Swansea.

U.S. 6/85 overlap northward through Commerce City to Interstate 76. I-76 briefly carries U.S. 85 north to north Commerce City, where it separates onto Canam Highway north to Brighton and Fort Lupton.

U.S. 87

Guides:

U.S. 87

U.S. 87 remains paired with Interstate 25 along an unmarked overlap throughout the entire state of Colorado. The route joins I-25 north from Raton, New Mexico and separates with the freeway at Glenrock, Wyoming. The former business loop through Colorado Springs was not posted as U.S. 87 either.

U.S. 285

Guides:

U.S. 285 – Hampden Avenue

U.S. 285 meanders northeast from Park County to Morrison, where it upgrades to a freeway leading east from the Hogback to Bear Creek Lake Park and the city of Lakewood. The freeway overlays Hampden Avenue east to Bear Valley and Fort Logan in southwest Denver.

Hampden Avenue transitions into a surface boulevard east from Sheridan through Englewood. U.S. 285 concludes east of Cherry Hills Village at Interstate 25 and the Hampden neighborhood. SH 30 begins there and continues the urban arterial east and north to Aurora as the former extension of U.S. 285 toward Colfax Avenue.

U.S. 287

U.S. 287 parallels the Interstate 25 corridor south from Longmont to Lafayette and Broomfield in the north Denver metro area. The route lines 120th Avenue east to Westminster and Federal Boulevard south to Federal Heights and Denver at Chaffee Park and Regis. U.S. 287 combines with Business Loop I-70/U.S. 40 east along Colfax Avenue to the Denver Central Business District and through to east Aurora. U.S. 287 runs concurrent with I-70 as a hidden route through to Limon.

State Highways

SH 2 – Colorado Boulevard

SH 2 is Colorado Boulevard from U.S. 285 (Hampden Avenue) at University Heights and Wellshire in Denver north I-76/U.S. 6 along the Brighton and Commerce City line. The state highway formerly extended north to SH 7, near U.S. 85, in Brighton.

Colorado State Highway 30

Guides:

SH 30

SH 30 is a mix of several urban and suburban roadways. The western section along Hampden Avenue, between I-25 and Havana Street at Kennedy, and along Havana Street north to Sixth Avenue in northwest Aurora, replaced the five-year extension of U.S. 285 north from I-25 in 1978. The remainder of the route serves Aurora along 6th Avenue east to I-225 and Buckley Air Force Base, and Gun Club Road south along side the E-470 toll road to Quincy Avenue (CR 30).
