COVID-19 UPDATE

E-470 is committed to following guidance set by the CDC and CDPHE in helping to slow and prevent the spread of COVID-19. At this time, the road widening project taking place on E-470 from Quincy Avenue to I-70 is continuing, with strict safety measures to protect construction teams and the public.

As part of these measures, a dedicated task force has been set up to ensure project teams are adhering to the latest guidance set by public health officials. Any previously-scheduled indoor meetings have been cancelled or are now being held virtually. Crews are practicing social distancing in the course of their work and all small group meetings taking place outside are being held to maintain social distancing.

E-470 and its sub-contractors will continue to follow this guidance and are ready to adjust to any new safety measures.

UPCOMING CONSTRUCTION: June 2020

Traffic Realignment and Lane Closures

There will be a single right lane closure for paving on northbound E-470 from Jewell Avenue to 6th Parkway/Stephen D. Hogan Parkway from 7 a.m. on June 29 to 5 p.m. on July 2.

There will be a single left lane closure for guardrail removals and installs on southbound E-470 from Smith Road to the 6th Parkway/Stephen D.

Another single left lane closure for guardrail removals and installs will take place on southbound E-470 from Jewell Avenue to Hampden Avenue from 7 a.m. on June 29 to 5 p.m. on July 2.

Every weekend from Saturday at 6 a.m. to Sunday at 9 p.m., there will be  single lane closures for two miles on southbound E-470 between 6th Parkway/Stephen D. Hogan Parkway and Quincy Ave. These closures will continue through the Summer and into Fall as crews work on the asphalt paving for the third lane expansion of the roadway. 

Please be advised the shoulder will be closed in this two mile work zone. Drivers should exercise caution when travelling through the area and adhere to sign posted speed limits. 

Asphalt Paving from 6th Pkwy./Stephen D. Hogan Pkwy to Quincy Ave.

In July, crews are expecting to begin the final asphalt surfacing on Northbound E-470 between 6th Pkwy./Stephen D. Hogan Pkwy. and Quincy Ave. Once this work is complete the new lanes will be striped.

Barrier Reset

A large portion of the concrete safety barrier will be removed on E-470 between 6th Pkwy./Stephen D. Hogan Pkwy. and Quincy Ave. in July. Barriers north of 6th Pkwy./Stephen D. Hogan Pkwy. will remain in place until structures and asphalt work are complete.

High Plains Trail Work

In July, crews will work to install the steel pedestrian bridge on the High Plains Trail. Later in the month, concrete paving of the trail will begin and is expected to continue through the summer.

All future work is weather dependentFor up-to-date closure information, stay tuned on our E-470 Facebook or Twitter page.






PROJECT UPDATE: June, 2020

E-470 Deck Pours

In June, crews worked to finish deck pours on the E-470 bridges over I-70, completing 12 out of 14 deck pours for the Road Widening Project. In addition, crews installed guard railings and approach slabs for these bridges. The final two deck pours will take place on the E-470 bridges over Smith Rd.

Coal Creek Bridge

This past month, expansion joint work was completed on Coal Creek Bridge. To accommodate this work, traffic was shifted to the shoulder over the bridge and the outer lanes were closed. Traffic is now in its final alignment.

19th St. and Colfax Bridges

In June, crews worked on the installation of guard railings and approach slabs for the E-470 bridges over 19th St. and Colfax Ave. Concrete finishing and bridge painting will take place next. 

Asphalt Paving from 6th Pkwy./Stephen D. Hogan  Pkwy to Quincy Ave.

Asphalt paving for the third lane expansion of E-470 between 6th Pkwy./Stephen D. Hogan Pkwy. and Quincy Ave. is almost complete in both directions. Final surfacing is now being placed on Southbound E-470 from 6th Pkwy. to Quincy Ave. 

Quincy Ave. and Gun Club Rd. Ramps

The construction of new on and off ramps for E-470 at Quincy Ave. and Gun Club Rd. is now underway with crews working on the grading, utility relocation, traffic signals and drainage work. Upcoming work will involve construction of a new structure to house tolling equipment at the new off ramp from NB E-470 to Gun Club with eventual ramp paving.

ABOUT THE E-470 ROAD WIDENING PROJECT: QUINCY TO I-70

E-470 begins construction this summer 2019 to add a third lane to the road in each direction between Quincy Avenue and I-70. E-470's 2014 full investment grade Traffic and Revenue Study indicated this eight-mile section of the road would need to be widened to maintain the level of service that our customers have come to expect and value. This current project is a continuation of the first phase of widening completed in 2017 between Parker Road and Quincy Avenue. Together, these projects allow E-470 to ensure a safe and reliable commute for our customers, improving mobility and accommodating projected growth to maintain a free-flow of traffic in the coming years. Project elements include:

Widening
  • Adding a third lane in each direction on E-470 between Quincy Avenue and I-70 (8 miles), and from Ramp B (from I-70 to southbound E-470) to the Smith Road/UPRR crossing.
  • Widening 14 northbound and southbound bridge structures at 7 bridge locations at (1) Coal Creek, (2) Ramp B, (3) Colfax Avenue, (4) I-70, (5) 19th Avenue, (6) Ramp E (from southbound E-470 to I-70), and (7) Smith Road/UPRR. 
Ramp Relocation
  • Relocating the northbound E-470 on- and off-ramps at Quincy Avenue.
Trail Extension
  • Extending High Plains Trail from Quincy Avenue to the new Stephen D. Hogan Parkway (6 miles).
Construction Improvement
  • Grading and drainage for a future fourth lane in each direction on E-470 from Quincy Avenue to Ramp B, and improving shoulders.
  • Building new wildlife deer fencing and game ramps.
  • Adding new overlay to existing pavement.

The E-470 Road Widening Project costs approximately $99 million and is funded through toll revenue; there are no local, state or federal funds being used. The northbound E-470 ramp relocations at Quincy Avenue are jointly funded by Arapahoe County, the South Aurora Regional Improvement Authority, and E-470. Construction is scheduled to be complete by the end of 2020.
