PacRim Engineering is responsible for assisting HNTB in the re-alignment and replacement of the Riverside Drive Bridge over the Los Angeles River. HNTB previously completed the environmental documents and is currently in the process of completing the civil and structural design. The new bridge features a two span prestressed concrete box girder structure to replace the existing single span steel truss bridge. PacRim’s scope of services include hydraulic studies, utility coordination, street lighting design and the process of regulatory permits from Army Corps of Engineers, State Regional Water Quality Control Board, and State Department of Fish and Game. The project complies with Caltrans Local Assistance Procedures. The Project is slated to begin construction early in 2011.
