Turnbull Canyon Road

Grade Separation Project

City of Industry and Los Angeles County

 

Phase 2 Closure Detour Route (March 3, 2025 - Summer 2027)

Crews will close Turnbull Canyon Road at the railroad crossing for the construction of an overpass starting March 3, 2025 and is expected to be completed summer of 2027.​​​​​​​​​​​​​

Project Description

The Turnbull Canyon Road Grade Separation Project will separate the roadway from the Union Pacific Railroad railroad tracks on Turnbull Canyon Road in the City of Industry/County of Los Angeles. Plans call for constructing a two-lane roadway overpass between Salt Lake Avenue on the north and Clark Avenue on the south to carry vehicles over the railroad tracks.

Project Status

The Turnbull Canyon Road Grade Separation Project is in the final engineering and design stage. State environmental clearance has been obtained, and right-of-way is being acquired. The project cost is estimated at $118 million. The estimated project completion date is Summer 2027.

​

Project Benefits and Project Need

The project would reduce an estimated 447 minutes of delay each day at the crossing, which is traversed by 59 trains per day and is expected to increase to 102 trains per day by 2042. Turnbull Canyon Road carries 19,000 vehicles per day (including 23 school buses, 9 passenger buses, and 11 hazmat trucks), which is projected to increase by 2025. The project would eliminate delays for emergency responders and crossing collisions. Emissions would be reduced, and locomotive horn noise would be eliminated. Since 2010, there have been 132 collisions, including two fatalities and 98 injuries.

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.
