Alameda Corridor East (ACE)
Gateway to America
San Gabriel Valley, California

The corridor project is comprised of a distance of 35 miles through San Gabriel Valley between East Los Angeles and Pomona, serving an area of approximately 1.9 million residents and 30 municipalities. The project connects the ports of Los Angeles and Long Beach to the transcontinental rail network, creating a faster, more efficient method of distributing the expected $314 billion in annual trade. The project components include grade crossing improvements (the project widens 17 roadways and grade separates 25 rail crossings throughout the most heavily used 55 crossings), safety upgrades, mobility improvements, traffic signal control measures and train traffic volume forecast.

JLP involvement includes railroad engineering, shoofly design, railroad safety, traffic engineering and civil engineering support services.
