Deck Replacement with Precast Concrete Segments: Project J8S0654, Route 64, Hickory County: First Precast Slab Panel Bridge in Missouri

The deck to be replaced in this project was on Bridge No. A0894, known as the Nemo Bridge. It was built in 1960 by the US Army Corps of Engineers over Pomme De Terre Lake. This 1698 ft. long steel bridge had wide flange girders with a 7 in. thick composite reinforced concrete deck. A preliminary survey showed that over 60% of the deck concrete was delaminated at the rebar level and that the deck needed replaced. HNTB Company, the design consultants, had originally designed the deck to be built by conventional methods one lane width at a time, which would have taken 2 years and required one-way traffic on the bridge during the whole construction. Closing the bridge would have caused a 30-mile detour. The Bridge Maintenance Engineer in Missouri Department of Transportation's (MoDOT’s) Springfield District came back from a National Prefabricated Bridge Elements Conference in St. Louis and suggested to the Project Manager using full thickness pre-fabricated deck panels to speed up the construction of the Nemo Bridge. This document describes the replacement of the deck with precast deck sections. It discusses construction time and costs as compared with traditional construction methods.
