Alameda Corridor East Grade Separation Project – Puente Avenue Grade Separation

Alameda Corridor East Grade Separation Project

Anil Verma Associates, Inc. (AVA) was part of the LAN Engineering team selected to perform Construction Management services for four grade separation projects as part of the Phase I ACE Project. AVA’s responsibilities included inspection, office engineering, and field engineering.

The ACE Project was a corridor-wide improvement program aimed at reducing vehicular congestion at railroad crossings and improving safety and mobility at 44 grade crossings, and at constructing 21 grade separations from East Los Angeles at Redondo Junction to Pomona in Los Angeles County, over a distance of 35 miles. The improvements were intended to reduce the impacts resulting from crossings of the Union Pacific Railroad (UPRR). The ACE Project serves an area of approximately 1.8 million residents and 30 municipalities, and connects the ports of Los Angeles and Long Beach to the transcontinental rail network.
