It also closed U.S. 40 for a short duration while replacing the existing bridge over the Blue River on U.S. 40. Corridor traffic flow of 110,000 vehicles per day continued throughout the project’s construction. The project included the construction of two 2,400-foot pre-stressed girder bridges, built to the outside of existing interstate bridges. Construction occurred while maintaining three lanes of live traffic in each direction on the interstate, and included the replacement of a 430-foot steel girder and overhead bridge truss with a pre-stressed girder bridge. The project included new grading and concrete paving at the approaches to the I-70 bridges and the reconfiguration and reconstruction of the ramps at the I-70 and Manchester Road Interchange. Over 36,000 square feet of new bridge decks, 100,000 cubic yards of onsite excavation and borrow from offsite to complete the required project embankments; additionally 22,500 square yards of new concrete pavement on aggregate base and 4,000 square feet of retaining walls, were all part of this project.
