C-470 construction continues

C470 grider erection

Construction on C-470 continues between Lucent and Quebec. The project includes trail reconstruction, temporary barrier and re-striping, earthwork and drainage operations, detour paving, retaining wall construction and Intelligent Transportation System (ITS) work. Additionally, crews continue to work both day and night on the demolition and widening of the Broadway and University bridges to accommodate the addition of the express lanes.

The Colorado Department of Transportation kicked off the C-470 Express Lanes project in the fall of 2016. This $276 million project will increase mobility and user choice along 12.5 miles of C-470 between I-25 and Wadsworth Boulevard. In the westbound direction, two Express Lanes will be built from I-25 to Colorado Boulevard and one Express Lane from Colorado Boulevard to Wadsworth. In the eastbound direction one Express Lane will be constructed along the length of the project between I-25 and Wadsworth Boulevard. Two general purpose lanes in each direction will remain free for motorists.

When the C-470 Express Lanes project is complete, motorists will have the option to use the Express Lanes for a faster, more reliable commute, or the two free general purpose lanes. Construction is about 20% complete and is expected to be fully completed in the spring of 2019.

Upcoming activity to include Erickson Bridge and South Platte River Bridge 

Erickson is the next bridge scheduled for widening and is expected to start mid-summer. The contractor will also begin bridge demolition and reconstruction of the eastbound and westbound South Platte River Bridges. These are the only two bridges that will be completely rebuilt as part of this project. During construction, the Mary Carter Greenway Trail will have intermittent flagging operations and full closures under the South Platte Bridge with two detours available for trail users. The closure and detours are scheduled to begin June 2017 and will last a maximum of six months. Information for the trail detours will be widely distributed and can be found at local bike shops. Detours can also be viewed at www.codot.gov/projects/C470ExpressLanes or requested through the project email C470info@flatironcorp.com or the project hotline number 303-347-0507.
