Magnolia Avenue Grade Separation

CITY OF RIVERSIDE

The 2-span steel girder railroad bridge provided for two tracks of the Union Pacific Railroad (UPRR) over a 4-lane major arterial street within a commercial area of the City.  The work required the construction of temporary soldier pile walls in order to keep traffic flowing along the Magnolia Avenue commercial corridor.  Permanent MSE walls were constructed for the underpass. A three-pump stormwater lift station was constructed to control storm flows within the underpass area. Southstar provided similar services for both the Columbia Avenue and Magnolia Avenue Grade Separation projects.  These services were:  project start-up and closeout; document control; constructability reviews; submittal, schedule, and safety reviews; inspection procedures; and quality assurance audits.
