The Interstate 70 Straight Creek Culvert Repair Project is located between Silverthorne (Exit 205) and the Eisenhower-Johnson Memorial Tunnel (Mile Point 213). The project will improve drainage and preserve infrastructure. Once complete, crews will have lined nearly one mile of pipes, extending the lifespan of culverts along Straight Creek. Crews are also upgrading inlets and grates connected to the system.
