I-70/SR 9 Interchange (BEL-70-17.73)

St. Clairsville, Ohio

This project included replacement of the existing I-70 twin structures over SR 9 with a longer three-span continuous steel beam bridge, improving site distance along SR 9. The westbound structure was constructed wider than needed and built part-width in order to maintain traffic. The eastbound structure was built to the required width in a single phase of construction while traffic was crossed over to the westbound side. Sheet piling, soldier pile and lagging, and temporary pier supports were required for maintaining traffic.
