Overview

• The overpass, spanning six lanes of I-25, measures 200 feet wide and 209 feet long, linking 39,000 acres of habitat for elk, mule deer and pronghorn.
• The project closes a nearly four-mile gap in the 18-mile I-25 South Gap mitigation system of underpasses and fencing between Castle Rock and Monument.
• Funded by the Infrastructure Investment and Jobs Act, the $15 million structure is managed by CDOT alongside the Federal Highway Administration, Colorado Parks and Wildlife and local partners.
• Colorado State Patrol’s summer awareness campaign follows two recent wildlife-vehicle fatalities and highlights an average of one crash per day along the corridor.
• Motorists can expect daytime and nighttime lane closures, reduced speeds and Express Lane shutdowns as crews pour the concrete deck and install wildlife fencing ahead of year-end completion.
