Colorado E-470 (Outer Loop)

E-470 - North/Outer
This mileage sign uses Denver International Airport as a control city, with distances also provided for the next two exits: Chambers Road and Jordan Road. Photo taken 11/10/03.
Backlit signs such as this one are the rule for the first five miles of E-470. The first five miles were the first segment of the freeway constructed, and they had a different standard for signage than the rest of E-470. This photo shows E-470 north at Exit 2, Peoria Road. Photo taken 11/10/03.
Mileage sign along northbound E-470 approaching Exit 3, Chambers Road, 1.75 miles; Exit 4, Jordan Road, two miles; and Exit 20, Junction Interstate 70, 19 miles. Photo taken 11/10/03.
View of the advance signage for the first toll plaza along northbound E-470. Photo taken 11/10/03.
Express Toll traffic uses the left lanes for automated toll collection, while cash patrons use the right lanes. Photo taken 11/10/03.
The toll plazas are visible after the overhead signs indicating the lane assignments. After this initial plaza, another four remain ahead before reaching Interstate 25/U.S. 87 at the north end of the metropolitan area. Photo taken 11/10/03.
The next mileage sign is situated immediately after the toll plaza, with the next exit being Exit 3, Chambers Road. Photo taken 11/10/03.

Northbound E-470 at Exit 3, Chambers Road. Photo taken 11/10/03.
Mileage sign along northbound E-470 approaching Exit 4, Jordan Road, one-half mile. Photo taken 11/10/03.
This sign almost looks like a California-style exit sign, with the exit number embedded in the back-lit sign. At this interchange, Jordan Road exits off E-470 north. Jordan Road parallels Parker Road (Colorado 83) between Lincoln Avenue and Arapahoe Road. Photo taken 11/10/03.
Mileage sign along northbound E-470 for Exit 5, Junction Colorado 83/Parker Road, 0.75 mile; Exit 9, Gartrell Road, 4.50 miles; and Exit 10, Smoky Hill Road, 5.50 miles. Photo taken 11/10/03.
Oddly enough, another mileage for two of the three aforementioned exits appears only a quarter mile after the previous sign. The only change is the deletion of Smoky Hill Road and addition of the distance to Interstate 70, some 16 miles north of here. Photo taken 11/10/03.
Northbound E-470 at Exit 5, Junction Colorado 83/Parker Road. Colorado 83 leads south to Parker, Castle Rock, and Colorado Springs; it heads north to Centennial, Aurora, Glendale, and Denver. Colorado 83 parallels Cherry Creek as it traces northwest into the city. This is the last of the backlit signs along northbound. Photo taken 11/10/03.
Between Exits 5 and 9, E-470 leaves Douglas County and enters Arapahoe County. The next exit along northbound E-470 is Exit 9, Gartwell Road. Photo taken 11/10/03.
As seen in this photo, E-470 turns north at Exit 9, Gartwell Road. Gartwell Road serves the southeastern corner of Aurora and Centennial. Photo taken 11/10/03.
Northbound E-470 approaching Exit 10, Smoky Hill Road, one mile. Smoky Hill Road leads east to Aurora Reservoir and northwest to Colorado 83/Parker Road via Quincy Avenue. Photo taken 11/10/03.
Northbound E-470 approaching Exit 13, Quincy Avenue, one mile. Photo taken 11/10/03.
Quincy Avenue leads east to the southern/eastern terminus of Colorado 30/Gun Club Road. Heading west, Quincy Avenue ends at its intersection with Colorado 83/Quincy Avenue at Cherry Creek State Park. Photo taken 11/10/03.
There is not much along E-470 between Quincy Avenue and Interstate 70. The power lines that parallel E-470 to the east (and visible in this photo) from here north to the airport actually overshadow Colorado 30/Gun Club Road. Photo taken 11/10/03.
Mileage sign approaching the next three exits: the second toll plaza along northbound; Exit 16, Jewell Avenue; and Exit 19, 6th Parkway. Photo taken 11/10/03.
The first exit after the second toll plaza is Exit 16, Jewell Avenue. Photo taken 11/10/03.
Northbound E-470 at Exit 16, Jewell Avenue. Note the milepost, which features a tiny E-470 shield mounted above the familiar green milepost. A Denver International Airport trailblazer shield is also present in the median. Photo taken 11/10/03.
Northbound E-470 shield on mainline just after Iliff Avenue. Photo taken 02/02/02.
Mileage sign along northbound E-470 approaching Exit 19, Sixth Parkway and Exit 20, Junction Interstate 70/U.S. 36-40-287. Photo taken 11/10/03.
Northbound E-470 approaching ExpressToll Service Center. Photo taken 11/10/03.
Northbound E-470 at Sixth Parkway, Exit 19. Sixth Parkway does not connect to the Sixth Avenue freeway in Denver. Photo taken 11/10/03.
Northbound E-470 approaching Junction Interstate 70 (and hidden U.S. 36-40-287), one and a half miles. At the time this picture was taken, the E-470/Interstate 70 junction is a signalized diamond interchange, with the signals regulating north and southbound traffic on E-470. This is Exit 20, but it is not a true exit in that traffic movements are made in relation to four traffic lights. The control cities here are for Limon to the east and Denver/Aurora to the west; Grand Junction is not the control city until west of Interstate 25. Photos taken 02/02/02 and 11/10/03.
These northbound E-470 yellow signs alert traffic that traffic lights at the Interstate 70 interchange may stop traffic. Since traffic is proceeding at a 70 mph pace without signals, this additional warning is warranted. Photo taken 11/10/03.
This variable message sign warns travelers again to slow down. Note the speed limit reduction signs too. Photo taken 02/02/02.
The speed limit has dropped to 55 mph, in anticipation of the traffic signals ahead. Also note the mileage sign, which show the upcoming intersections. Photo taken 11/10/03.
Now the traffic lights are coming into view. Interstate 70 runs under E-470 at this interchange. The first traffic light is for Colfax Avenue, which at this point is merely the frontage road for Interstate 70. It may be the old alignment for U.S. 36-40-287. Photo taken 02/02/02.
Colfax Avenue roadside signage approaching the first traffic signal. Photo taken 11/10/03.
Colfax Avenue east leads to Gun Club Road, a north-south road that parallels E-470 as it passes through the eastern fringes of Aurora. Photo taken 11/10/03.
This picture shows the context of the traffic lights and intersection signage from the perspective of E-470 northbound. Note the three sets of lights: one for Colfax Avenue, one for Interstate 70 eastbound, and one for Interstate 70 westbound. The fourth light for Smith Road is not visible from here. The pull-through overhead sign was modified between 2002 and 2003 to reflect the extension of E-470 north to Interstate 25 (hence the control city of Fort Collins). Photos taken 02/02/02 and 11/10/03.
Northbound E-470 signage for Interstate 70 east and west at the traffic signals. This is a diamond interchange. The control city for E-470 north is 120th Avenue, but this will change once the E-470 extension to Interstate 25 is complete. The Denver International Airport is also a bit further north at this point, hence the airplane logo on the sign. However, airport travelers should not plan on taking 120th Avenue to get to the airport; Pena Boulevard is the best route to the airport. So in that regard, this sign is a bit confusing. Photo taken 02/02/02.
Northbound E-470 at Junction Interstate 70 westbound. E-470 leaves Arapahoe County and enters Adams County as it passes over the mainline. The Smith Road traffic signal is visible in the distance beyond this light. Photo taken 02/02/02.
Northbound E-470 at the Smith Road intersection and traffic signal. The freeway resumes north of here, as evidenced by the "Begin Tollway" sign. Photo taken 11/10/03.
Mileage sign along northbound E-470 for the third toll plaza, 56th Avenue, and 64th Avenue. Photo taken 11/10/03.
The toll plaza approaches on northbound E-470. This signage is typical for each toll station. ExpressToll is similar to Fastrack and other automatic toll collection systems. Cash users must use the right lane to pay. Photo taken 02/02/02.
This is the next signage assembly approaching the toll barrier. The symbols on the sign are supposed to assist motorists in determining which lane to use, depending on whether they carry ExpressToll or cash. This is not a ticket-based toll collection system; there are toll barriers at set intervals along E-470. Photo taken 02/02/02.
This is the last in the series of three advance signs prior to the toll booth. In spite of this signage, we spotted someone quickly move from the far left lane over to the right lane so they could pay cash. This is similar to the toll barriers used in Orange County California, which allows through traffic to use the left lanes for the FasTrack automated toll collection system. Photo taken 02/02/02.
Northbound E-470 at the third toll barrier. This design is typical of the toll plazas along the E-470 route. Two more toll plazas remain along northbound E-470. Photo taken 02/02/02.
Northbound E-470 approaching Exit 24, 56th Avenue, one mile. Photo taken 11/10/03.
Mileage sign along northbound E-470 for Exit 24, 56th Avenue; Exit 25, 64th Avenue; and Exits 28A-B, Pena Boulevard. Photo taken 11/10/03.
Northbound E-470 at Exit 24, 56th Avenue. 56th Avenue leads west to the southern border of the Rocky Mountain Arsenal National Wildlife Refuge then onward to Havana Street and Interstate 70/U.S. 36. Photo taken 11/10/03.
Mileage sign along northbound E-470 approaching 64th Avenue (Exit 25), Pena Boulevard, and ... another toll barrier! Photo taken 02/02/02.
Northbound E-470 at 64th Avenue (Exit 25). Since this exit is located immediately after a toll barrier, there is no collection on the offramp here. Photo taken 02/02/02.
Northbound E-470 approaching Pena Boulevard (Exit 28) two miles. Pena Boulevard is a freeway that connects Interstate 70 near the Interstate 225 interchange with Denver International Airport. It is named after former Denver Mayor Federico Pena, who was President Clinton's Secretary of Transportation. Once E-470 is constructed to the north of Interstate 76, it will provide a direct route from areas north of the Denver metropolitan area to the airport. Photo taken 11/10/03.
Northbound E-470 shield. At this point, E-470 turns a bit westward so that the Front Range is clearly in view. This vista may have inspired the E-470 shield design. The white caps of the distant peaks on this clear winter day are very distinct in the horizon. E-470 enters Denver County as it passes by this interchange, then returns to Adams County just north of the interchange. Photo taken 02/02/02.
Mileage sign along northbound E-470 approaching Pena Boulevard, one mile. There is not much traffic on this toll road. Photo taken 02/02/02.
Northbound E-470 approaching Exit 28A, Pena Boulevard eastbound, one-half mile. The interchange between E-470 and Pena Boulevard is a modified cloverleaf. Photo taken 11/10/03.
Northbound E-470 at Pena Boulevard eastbound. This is the main route into the airport. The next exit is for Pena Boulevard westbound. This interchange is not configured in the same manner for southbound E-470. Photo taken 11/10/03.
Northbound E-470 at Pena Boulevard westbound, Exit 28B. Photo taken 11/10/03.
After the Pena Boulevard interchange, E-470 has a reassurance shield, then approaches its fourth toll plaza along northbound. Photo taken 11/10/03.
Mileage sign along northbound for the next three exits: the Toll Plaza; Exit 31, 96th Avenue/Rocky Mountain Arsenal National Wildlife Refuge; and Exit 32, 104th Avenue. Photo taken 11/10/03.
Now past the fourth toll plaza, northbound E-470 approaches Exit 31, 96th Avenue, 1000 feet. Photo taken 11/10/03.
Northbound E-470 at Exit 31, 96th Avenue. 96th Avenue heads west to Rocky Mountain National Arsenal Wildlife Refuge. West of the preserve (a Superfund clean-up site), 96th Avenue connects with westbound Interstate 76. Photo taken 11/10/03.
The next exit along northbound is Exit 23, 104th Avenue. 104th Avenue is a major east-west arterial, connecting to Interstate 76 and Colorado 2 in Commerce City, then continuing west as Colorado 44 to U.S. 287/Federal Boulevard. West of Federal Boulevard, 104th Avenue reverts to local maintenance, meeting U.S. 36 in Westminster. Photo taken 11/10/03.
Mileage sign along northbound E-470 approaching Exit 32, 104th Avenue, 0.75 mile and Exit 34, 120th Avenue, 3.50 miles. Photo taken 11/10/03.
Northbound E-470 at 104th Avenue, Exit 32. These exit numbers track mileage south to the terminus at Interstate 25 and Colorado C-470. C-470, by comparison, does not have any exit numbers at the time these pictures were taken. We included two pictures here to show a minor yet interesting change in the scenery. In the first picture, the steel lattice structure for the power line has a triangular insulator, but in the second photo, that insulator has been replaced. First photo taken 02/02/02; second photo taken 11/10/03.
Mileage sign along northbound for Exit 34, 120th Avenue to Interstate 76 West and Exit 35, Junction Interstate 76 East. Photo taken 11/10/03.
Northbound E-470 at Tower Road overcrossing. This bridge is of a standard design for E-470 overpasses. The words "Tower Road" are engraved at the end of the bridge, a design unique to E-470. The orange-red guardrail at the top of the bridge is also very distinctive. The Front Range is framed by the bridge here, and the signage in the distance is shown in the next picture. Photo taken 02/02/02.
120th Avenue west connects to westbound Interstate 76; there is no direct connection to Interstate 76 via Exit 35. Photo taken 11/10/03.
At the time this picture was taken, northbound E-470 ended at 120th Avenue, but construction was evident north to Interstate 76 and west to Interstate 25. This sign has since been replaced with the following sign. Photo taken 02/02/02.
This mileage sign replaced the mileage sign presented in the previous photobox. The mileage to 120th Avenue was changed to reflect the distance to the exit ramp rather than the actual intersection with 120th Avenue. Photo taken 11/10/03.
This picture shows northbound E-470 at the former northern terminus at 120th Avenue (back in February 2002). 120th Avenue provides connections to the local arterials and Interstate 76. Photo taken 02/02/02.
Northbound E-470 at Exit 34, 120th Avenue. Photo taken 11/10/03.
As E-470 approaches Interstate 76, it changes from a northerly direction to a northwesterly trajectory, making its change between Exit 34 (120th Avenue) and Exit 35 (Junction Interstate 76). Photo taken 11/10/03.
The only connection along northbound is to east Interstate 76. Use either Exit 34/120th Avenue or Exit 38/U.S. 85 to reach Interstate 76 west. This is because Interstate 76 is angled southwest to northeast, thus making a direct connection here a bit less intuitive than using the connecting surface streets. Photo taken 11/10/03.
Northbound E-470 at Exit 35, Junction Interstate 76 East. Photo taken 11/10/03.
Northbound E-470 approaching Exit 38, Junction U.S. 85. U.S. 85 heads north to Brighton, Fort Lupton, Greeley, and Cheyenne, Wyoming. Southbound U.S. 85 joins westbound Interstate 76 en route to downtown Denver. Photo taken 11/10/03.
As noted on this advance sign, U.S. 85 provides another connection to westbound Interstate 76. Interstate 76 is signed for Denver, but it also connects to Interstate 70 toward the foothills and mountains of the Front Range. Photo taken 11/10/03.
U.S. 85 is one of three major highways that span the northern Front Range, the others being Interstate 25 and U.S. 287. Although U.S. 85 is not a freeway, it is a divided highway/expressway from Interstate 76 north to Greeley. Meanwhile, E-470 north turns west to approach its final junction with Interstate 25. Photo taken 11/10/03.
As is standard on E-470, the name of the highway passing over the tollway is inscribed into the bridge. In this case, "US 85" is placed on the bridge abutment. Photo taken 11/10/03.
The final mainline toll plaza on northbound E-470 is near Milepost 39; the next exit after the toll barrier is Exit 43, Colorado Boulevard. Photo taken 11/10/03.
Northbound E-470 approaching Exit 43, Colorado Boulevard, one mile. This section of Colorado Boulevard is discontinuous with the section of Colorado Boulevard that follows Colorado 2 through Denver. Photo taken 11/10/03.
This mileage sign provides the distance to the next three exits: Exit 43, Colorado Boulevard; Exit 45, York Street; and Exit 47, Junction Interstate 25/U.S. 87. Photo taken 11/10/03.
Now reaching Exit 43, Colorado Boulevard leads north to Colorado 7/160th Avenue to the north and Colorado 44/104th Avenue to the south. Photo taken 11/10/03.
Northbound E-470 approaching Exit 45, York Street, one mile. This section of York Street links 144th Avenue to the south with Colorado 7/160th Avenue to the north. Photo taken 11/10/03.
Like many rural highways and suburban streets in Adams County, York Street carries the same name as the Denver city street called York Street. Both York Streets run north-south and follow the same trajectory. York Street fits between Downing Street and Colorado Boulevard on the street grid. Photo taken 11/10/03.
Mileage sign along northbound E-470 approaching its final exit, Exit 47, Junction Interstate 25. Now that the Northwest Parkway has opened west of Interstate 25, this mileage sign has been filled out to include exits for Lowell Boulevard and U.S. 287/Dillon Road. Photo taken 11/10/03.
This blocked off sign was converted in November 2003 since the Northwest Parkway was not yet open; however, this sign is now revealed to indicate that through traffic for the Northwest Parkway should remain in the left lanes. Photo taken 11/10/03.
The final exit on northbound E-470 is here, at Exit 47, Junction Interstate 25. The freeway continues straight ahead to switch onto the Northwest Parkway, and there are end shields present just after this exit. However, at the time this picture was taken, the freeway was still closed off. The Northwest Parkway opened only a few weeks after our visit to Denver, in the latter part of November 2003. Photo taken 11/10/03.
View of the E-470/Interstate 25/Northwest Parkway interchange as seen from the transition ramp from northbound E-470 to Interstate 25. It is one of two symmetrical stack interchanges in the Denver metropolitan area. Photo taken 11/10/03.
Signage for Interstate 25/U.S. 87 along the transition ramp from E-470 north. Interstate 25 leads north to Fort Collins and Cheyenne, Wyoming. It heads south to downtown Denver, Colorado Springs, and Pueblo. Photo taken 11/10/03.
