As part of the ongoing Road Widening Project, Quincy Avenue will be restricted to one lane between the E-470 northbound and southbound ramps from 9:00 a.m. - 3:00 p.m. on Monday, March 27 through Wednesday, March 29 to install bird netting.

E-470 speed limits are reduced from 75 mph to 65 mph along the eight miles between Parker Road and Quincy Avenue during construction.
Additionally, the girders for the bridge over Cherry Creek are being set on Wednesday, March 29 through Saturday, April 1. Expect single and double left lane restrictions on E-470 from 7:00 p.m. - 5:00 a.m. in the vicinity of the bridge. The Cherry Creek Trail is expected to be closed at these same times to ensure the safety of cyclists and pedestrians, but will be open during the day. Trail detours will be clearly marked.

Preparations for visual buffering installation will begin in April at locations identified through technical analysis. Click here to view the visual buffering renderings and locations.

​E-470 began construction in the spring of 2016 to add a third lane to the road in each direction between Parker Road and Quincy Avenue. Traffic along this eight-mile stretch has increased approximately 13 percent each year since 2013. E-470's 2014 full investment grade Traffic and Revenue Study indicated this section of the road would need to be widened by 2018 in order to continue operating at the required level of service. The Road Widening Project will ensure a safe and reliable commute for travelers. Project elements include:

  • A third lane in each direction between Parker Road and Quincy Avenue
  • The widening of six (6) bridges as shown on the project area map
  • A multi-purpose pedestrian/bike trail
The project budget is approximately $90 million and is being funded by the E-470 Public Highway Authority through tolls and E-470 reserves. Construction is scheduled to be complete by the end of 2017.



Visual Buffering Renderings and Locations


The construction approach and schedule prioritize safety and convenience for our customers. Key construction elements include:

  • Construction will take place on two-mile segments at a time
  • Two (2) lanes will remain open in each direction during weekday rush hours (6:00 a.m. – 9:00 a.m. and 3:00 p.m. – 7:00 p.m.)
  • A concrete barrier will separate the driving public from construction
For the safety of the traveling public and the construction crews some night work will take place during the project. E-470 will limit night work as much as possible and will communicate night work through overhead and local signage. Expect minimal delays during these occurrences.
