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.

Project Description

The project will focus on enhancing transportation infrastructure and safety at two Union Pacific Railroad (UPRR) at grade crossings located at Hamilton Boulevard and Park Avenue in the City of Pomona. Key elements of this project include: 

  • Roadway modifications: Implementing a road diet and install Class 2 buffered bike lanes to close a critical bicycle network gap along Hamilton Boulevard (from Orange Grove to Mission) and Park Avenue (from W. Commercial to 3rd St.)​

  • Railroad Safety Upgrades: Install pedestrian swing gates, pedestrian alert systems, right-of-way fencing and railroad crossing signage to improve safety for both pedestrian and cyclist. 

  • Pedestrian Enhancements: Construct new and enhanced widened sidewalks and add crosswalks and one pedestrian refuge island to improve safety and accessibility. 

  • ADA Accessibility: Install curb ramps compliant with the American with Disabilities Act (ADA) at key crossing points. â€‹

​

Project Status

ACE selected a firm in February 2015 to design the proposed at-grade crossing safety improvements. The project is currently at 95% design complete. The design is estimated to be completed in Spring 2025. Total project cost is estimated at $10 million.

​

Project Benefits

The project will significantly improve the safety and connectivity in the city. The upgrades will close a critical north-south bicycle network gap and enhance connectivity between downtown Pomona's Key Destinations such as Western University, the Pomona Arts District and County Services such as low income housing, elementary schools, community centers and the Pomona Transit Center. The improvements will ultimately enhance mobility and the quality of life for the residents of Pomona and visitors.
