The westbound lanes of I-44 at the Gasconade River east of Lebanon were opened to traffic after being closed for only 20 days instead of 60 days because of a new-to-Missouri “bridge jacking” construction technique.
A new 670-foot long bridge deck with underlying girders attached — weighing 2,000 tons — was built next to the existing bridge. Hydraulic jacks were used to slide the new superstructure into place in one piece during a 10-hour operation on one day.
