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: September 2020

Full Closure of SB E-470 at Smith Rd

In September, crews will continue the substructure work on the E-470 bridges over Smith Rd. and the Union Pacific Railroad. To facilitate this, southbound E-470 will be closed at Smith Rd. on September 14 and 16 from 7 p.m. to 6 a.m. with traffic detoured through the I-70 interchange. 

Asphalt Paving

Lane closures will continue to take place on northbound E-470 between Quincy Ave. and 6th Pkwy./Stephen D. Hogan Pkwy as crews work on asphalt paving. 

Traffic Realignment and Lane Closures

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. 

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






PROJECT UPDATE: August, 2020

E-470 Bridges

In August, crews continued to work on the bridge deck waterproofing and asphalt overlay for multiple E-470 bridges, including those over Colfax Ave. and 19th Ave. Crews also worked on the final painting of the southbound E-470 on-ramp and off-ramp for I-70, and replaced expansion joints on the bridges over I-70.  

New E-470 Ramps

Subgrade and asphalt paving work took place this month for the new on and off ramps for E-470 at Quincy Ave. and Gun Club Rd. Next, crews will move on to final asphalt finishing and painting, with the aim to have these ramps open by late fall. 

Asphalt Paving

This month lane closures took place on northbound E-470 to allow crews to begin the final asphalt surfacing between Quincy Ave. and 6th Pkwy./Stephen D. Hogan Pkwy. Last month, crews completed the asphalt paving on the southbound side of the roadway which is now open to the traveling public between Jewell Ave. and Quincy Ave.

High Plains Trail

In August, concrete pours took place on the High Plains Trail to help tie together the long stretches of paving that have already been set. Crews will continue this work in September.

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.
