Abstract: The Creve Coeur Lake Memorial Park (CCLMP) Bridge is the first major concrete segmental bridge constructed in Missouri, and is part of the Page Avenue Extension (Missouri Route 364) near St. Louis, Missouri. The Missouri Department of Transportation (MoDOT) built the extension to provide an additional route for commuters between St. Louis County and St. Charles County to the northwest of the city, relieving heavy congestion from the current corridors of I-70, to the north, and Highway 40 to the south. The CCLMP Bridge is a 2,675 ft. long, cast-in-place, post-tensioned, concrete segmental box girder structure with sloping, variable depth web walls, built by the balanced cantilever method. It includes nine spans from 185 ft. to 469 ft., and carries five lanes of traffic with full width shoulders in each direction on twin structures, built 4 inches apart at the deck. The deck of each directional structure is composed of two, single-cell box girders joined at the top for a total deck width of 86 ft. Each box is supported by a single, normally reinforced, concrete column to the pile cap, drilled shaft cap, or spread footing foundation, bearing directly on sound rock. This paper will briefly outline the technique of segmental construction by the balanced cantilever method. It continues by describing the use of the "maturity method" for concrete strength assessment, and its function as part of a cold weather concrete plan. The paper also describes the application of a silica-fume concrete deck overlay, and some of the problems encountered. These two specific aspects of the endeavor have applications to many other transportation projects.
