Nogales Street Grade Separation and Roadway Widening Project

City of Industry and Los Angeles County

Project Description

ACE constructed a six-lane roadway underpass and double-track railway bridge to completely grade separate Nogales Street with the railroad (Los Angeles Subdivision) between San Jose Avenue and Gale Avenue/Walnut Drive North. Gale Avenue and Walnut Drive North near Nogales Street was widened to two lanes in each direction to ease a traffic chokepoint.

Project Status

Construction of the Nogales Street Grade Separation began in May 2013. With the completion of the temporary railroad crossing at Charlie Road, Nogales Street between San Jose Avenue and Gale Avenue/ Walnut Drive North was closed in March 2014 for underpass and bridge construction. Nogales Street re-opened to traffic in June 2016. The cost of this project was $120.8 million.

Project Benefits

The project eliminates the potential for train-vehicle collisions and delays for emergency responders and reduces emissions and locomotive horn and crossing gate noise. Ten crossing collisions were recorded over the 10 years ending in 2014 when the roadway closed for construction. The crossing is used daily by more than 40,000 vehicles and 49 trains a day, projected to increase to 91 trains by 2025.
