Cost:  $47.5 Million

Anil Verma Associates, Inc. provided Construction Management services with responsibilities for Inspection, Safety, Field Engineering, and other services. The project consisted of bridges, underpass roads, trackwork, retaining walls, sound walls, landscape, drainage, and a loop connector road that replaced the former intersection of Nogales and Valley Blvd.


The Nogales Street Grade Separation Project, located in West Covina, required the Nogales Street be lowered twenty (20) feet approximately below Valley Blvd. and the railroad tracks. The project required the construction of two (2) bridges. One bridge was built to carry motorists along Valley Blvd., one bridge for trains over Nogales Street.  A loop connector road replaced the former intersection of Nogales and Valley. An underpass access road along Nogales Street was built utilizing Caltrans standard construction guidelines and details, and this included RC retaining walls on CIDH piles, sound walls (per Caltrans Standards), flood control & prevention, median and mitigation landscape with a drip irrigation system, dedicated pedestrian walkways, road signage, traffic signals, road striping, storm drainage, installation of new curbs, gutters, and sidewalks.
