INSTRUMENTS TELL INSIDE STORY OF BRIDGE

A trough-shaped prestressed concrete railroad overpass is serving as a test for the California Department of Transportation which is investigating this method of bridge construction as compared with a comparable cellular box girder bridge. The railroad bridge cost 20% less to build than the conventional type and is now instrumented for measurement of static and dynamic effects. The $390,000 study, funded cooperatively by California DOT and FHWA, will compare theoretical design analyses with actual structural reactions. More than 500 gages and meters were incorporated as the bridge was built.
