I-70 & CO 58 Interchange Project

Project complete

Project Overview

On February 7, 2007, the Colorado Department of Transportation (CDOT) began an interchange improvement project at I-70 and Colorado Highway 58 in order to improve access. The $23 million project will construct two new ramps and reconstruct or realign three other ramps:

  • A new ramp from eastbound I-70 to westbound CO 58 will be constructed
  • A new ramp from eastbound CO 58 to westbound I-70 will be constructed
  • The existing ramp from eastbound CO 58 to eastbound I-70 will be realigned and reconstructed without replacing the existing bridge
  • The existing ramp from westbound I-70 to westbound CO 58 will be realigned and reconstructed
  • The existing ramp from Youngfield Street to eastbound I-70 will be relocated approximately 1/4 mile to the south to accommodate a longer acceleration lane.

The project also constructs the 40th Avenue underpass, which will add access for the Cabela's development in the future. The underpass will cost approximately $7.2 million and is funded by the City of Wheat Ridge.
