I-70 and SH 58 Interchange Project

On February 7, 2007, the Colorado Department of Transportation (CDOT) began an interchange improvement project at I-70 and State 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 SH 58 will be constructed
• A new ramp from eastbound SH 58 to westbound I-70 will be constructed
• The existing ramp from eastbound SH 58 to eastbound I-70 will be realigned and reconstructed without replacing the existing bridge
• The existing ramp from westbound I-70 to westbound SH 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.
