Overview
The C-470 Express Lanes Segment 1 project will be constructed, managed, owned and operated by CDOT. The project is supported by the C-470 Corridor Coalition, and Douglas County is providing CDOT partial funding.
Funding all the scope items listed below for Segment 1 is contingent upon net proceeds from toll revenue projections, combined with RAMP funds and other revenue sources.
- Adding two express lanes westbound from I 25 to Colorado, one tolled express lane between Colorado and Wadsworth westbound, and one tolled express lane eastbound from Platte Canyon Road to I 25.
- Full reconstruction of the existing pavement.
- Adding auxiliary lanes at selected locations.
- Improving on-ramps and off-ramps to current standards (including ramp metering where appropriate), and including construction of direct-connect ramps to the westbound managed tolled lanes to accommodate traffic from I 25 northbound and southbound, and from E 470.
- Realigning substandard curves.
- Safety and operational improvements between I-25 and Quebec.
- Widening of existing bridges throughout the project area.
- Replacing the bridges over the South Platte River.
- Installing water-quality features designed to current standards.
- Installing noise barriers where required.
- Installing ITS elements and tolling equipment.
- Installing the appropriate signing and striping required for the proposed corridor improvements.
Additionally, the project includes adding grade separations for the C-470 multi-use trail at Colorado Boulevard and Quebec Street, where grade separations are required at the off-ramp, on-ramp and under Quebec Street.
HOV Lanes
There will be no HOV/carpool lanes within the C-470 corridor. 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.
