Orange Avenue Grade Separation

City of Industry

Project Description

The Orange Avenue railroad bridge is part of the Sunset Avenue Grade Separation Project which elevated the Union Pacific Railroad tracks on a 1.6 mile concrete-walled flyover structure with steel railroad bridges spanning Sunset and Orange Avenues in the City of Industry. The bridge over Sunset Avenue is 132 feet long and the Orange Avenue bridge is 66 feet long. The flyover structure is 45 feet wide and reaches a height of 32 feet.

Project Status

Major construction activities for the $93.8 million project began in January 2007 with the closure of California Avenue. Sunset Avenue and Orange Avenue at Valley Boulevard were closed for construction after California Avenue reopened in November 2007. Sunset Avenue reopened to traffic in November 2010. Orange Avenue reopened to traffic in March 2011.

Project Impacts

With completion of construction, traffic wait times due to trains on the mainline track, locomotive horn noise and the potential for deadly collisions have been eliminated.
