CONCRETE SEGMENTS ACCENT SAN ANTONIO PROJECT
One of the most extensive uses of prestressed concrete segmental box girders in the nation, the elevated San Antonio 'Y' project, rebuilding the intersection of I-35 and I-10 in Texas, is described. The segmental design of the urban viaduct has afforded a lack of interference with existing traffic. Although the complex, match-cast design of the concrete segments together with an abundnce of curvatures, ramps, varying segment widths and superelevation of each segment has led to contractor claims and midstream design changes, the project is on schedule, and the total cost has declined from that of estimates. The San Antonio Y is being built in 9 major contracts covering 22 projects. The double-decking represents $100 million in precast concrete segmental construction. Segmental units were specified for aesthetics and for maintaining traffic. Other highlights of the construction are also noted.
