Project Phase 2B is Underway

Crews have started work on the last half of Phase 2 construction to improve capacity on Wadsworth Boulevard between Highland Drive and 10th Avenue in Lakewood. The project is expected to be completed in August 2017.


Crews have completed:

  • the east sections of a three-cell concrete box culvert with wing walls;
  • the east section of the pedestrian box;
  • a storm sewer stretching from 10th Avenue to Highland Drive;
  • concrete pavement;
  • lighting;
  • a sidewalk from 10th Avenue to Highland Drive;
  • a trail leading from the sidewalk to the pedestrian box; and
  • gulch improvements.

Upcoming work includes:

  • completing a box culvert and the pedestrian box near Highland Drive;
  • completing a multi-use trail;
  • concrete paving and sidewalks; and
  • making improvements to drainage and to Lakewood Gulch.


Most work will be completed during daylight hours, Monday through Friday, but there could be some construction activities during overnight hours or on the weekend if needed.

Phase 2B began on March 16, 2017, and is expected to last until early May. After Phase 2B is complete, the project enters Phase 3, which will include median work and work on items for the project's punchlist. Final striping will be done after all other phases are complete.

Travel Impacts

  • Speed limits will remain at 40 mph.
  • The sidewalk on the west side of Wadsworth Boulevard through the project is closed. The brand new sidewalk on the east side is open instead.
  • Minimal lane closures are expected.
  • Minimal night work is expected.

In March 2016, CDOT started construction to improve capacity on Wadsworth Boulevard, between Highland Drive and 10th Avenue. 

Phase 1

Work on the first stretch of roadway to improve Wadsworth Boulevard capacity between 10th Avenue and Colfax was completed in summer 2015. Improvements included:

  • providing three through lanes on Wadsworth Boulevard in Lakewood;
  • adding a center median for safer operations;
  • adding a new concrete box culvert to improve drainage in the area; and
  • adding a 10-foot-wide multi-use path on both sides of the roadway.

This was the first phase of construction from the US 6 and Wadsworth Interchange Study. The City of Lakewood is contributing significantly to the project costs. Multi-modal access to the new RTD light rail station will also be provided.

Further construction in the area has been laid out in the US 6 and Wadsworth Interchange Study.
