Project Description

The Puente Avenue Grade Separation Project will separate the roadway and the railroad tracks on Puente Avenue at Valley Boulevard in the City of Industry and unincorporated area of Los Angeles County. Plans call for constructing a roadway underpass on Puente Avenue with bridges for Valley Boulevard and the Union Pacific Railroad tracks and include a loop connector road west of Puente Avenue and south of Valley Boulevard. Third Avenue will remain open to Puente Avenue.

Project Status

Major construction activities began in June 2015 with the closure of Puente Avenue for approximately 36 months. Construction of the connector road has been completed and utility relocations are underway. Project cost is estimated at $97.4 million.

Project Impacts

The project will reduce traffic congestion by an estimated 13 vehicle-hours of delay each day due to lowered gates at the crossing which is traversed by 20 trains per day, projected to increase to 42 trains per day by 2025. Puente Avenue carries 31,000 vehicles per day which is projected to increase to 33,100 vehicles by 2025. The project will eliminate delays for emergency responders and crossing collisions, with five collisions recorded over the last 10 years. Emissions will be reduced and locomotive horn noise eliminated. Project construction will create 1,780 jobs.
