A beautiful sunrise greets the #OHLAUSA project team as they start their workday at the Montebello Corridor Grade Separation project in Montebello, California. This contract is one of several Grade Separation procurements that OHLA USA has performed for the San Gabriel Valley Council of Governments.
The project, which was awarded in 2023, calls for the construction of a bridge at the Union Pacific Railroad crossings at Montebello Boulevard and Olympic Boulevard, creating a roadway underpass at both locations. The contract will eliminate potential train collisions with vehicles since motorists will travel below grade while trains traverse the track unimpeded. The effort will also significantly reduce traffic congestion and emissions and enhance safety by upgrading signal systems and adding pedestrian crossings.
Located eight miles east of downtown Los Angeles, the grade separation requires the demolition and excavation of substructure elements followed by the construction of a steel girder bridge with concrete fascia and earth retaining structures. Also included is the installation of CIDH piles, abutments, and columns. To advance the project, the OHLA USA team will grade and prepare the site within the Union Pacific Railroad right of way, construct support of excavation systems, build roadway structural sections, and construct a temporary track detour to allow trains to remain operational through the construction zone. Extensive paving activities and concrete work for curbing, gutters, and sidewalks are also part of the contract.
