c 470 express lanes

What's New?

The Project officially began construction on November 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 intersection at Broadway and mainline C-470 between Quebec and Lucent have 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. 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.

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:
