C-470 Express Lanes

c 470 express lanes

What's New?

Project construction officially started on Nov. 1, 2016. Travelers should now see new signage, construction equipment, and increased activity along mainline C-470 between Lucent and Quebec.

Temporary concrete barrier has been set along the shoulder to allow workers to safely perform work such as earthwork, installation of conduit for Intelligent Transportation System (ITS) equipment, soil compaction for the future trail and road-widening work, potholing for utilities, surveying and geotechnical drilling for soil testing. The Broadway and mainline C-470 intersection between Quebec and Lucent has been restriped, and bridge foundation work is underway at Broadway, University, and Big Dry Creek.

New bridge girders have been set at the Broadway bridge, with the same activity to occur soon at the University bridge. Parts of the Centennial Trail between Broadway and Big Dry Creek have been realigned with asphalt pavement. Be sure to follow detour signs and obey flaggers when present.

Project Overview

The C-470 Express Lanes project will increase mobility and user choice along 12.5 miles of C-470 between I-25 and Wadsworth Boulevard. The $276 million project includes the following improvements:

  • Mobility Improvements:
    • Two additional westbound Express Lanes constructed from I-25 to Colorado Boulevard, and one additional Express Lane from Colorado Boulevard to Wadsworth.
    • One additional eastbound Express Lane constructed along the length of the project, between I-25 and Wadsworth Boulevard.
  • Additional safety and infrastructure improvements:
    • full reconstruction of existing pavement
    • new auxiliary lanes at selected locations
    • on- and off-ramp improvements
    • realignment of substandard curves
    • widening of existing bridges
    • replacing the bridges over the South Platte River

Funding

The project is funded by $110.6 million in combined state and federal funding, and $10 million from Douglas County. The remainder will be funded via a loan repaid by toll revenues from the Express Lanes.


About Express Lanes

The C-470 Express Lanes project will add Express Lanes in addition to the existing, free general-purpose lanes. Drivers will always have a choice of using the free existing lanes or paying a toll to use the Express Lane.

There will be no HOV/carpool lanes within the C-470 corridor.

Express Lanes increase roadway capacity and help to manage congestion on highways. The use of toll pricing during peak travel times reduces delays, manages congestion and maintains reliable travel times. Express Lanes are currently open on:
