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.
