MONTEBELLO, Calif. – In a news release, the OHLA announces it has been awarded two contracts to construct two projects.
In a news release, the OHLA announces it has been awarded two contracts to construct two projects: the Montebello Corridor Grade Separation and the Alondra Park Multi-Benefit Stormwater Capture projects.
The first contract is valued at $127 million to improve rail safety and the flow of traffic in Montebello. According to the release, the contract calls for construction of a bridge eight miles east of downtown Los Angeles at “the Union Pacific Railroad crossings at Montebello Boulevard and Olympic Boulevard.” This would create an underpass at both of these locations, therefore eliminating train/vehicle collisions. In addition, there will be reduced traffic congestion, added pedestrian crossings, and upgraded signal systems.
The project includes the “demolition and excavation of substructure elements followed by the construction of a steel girder bridge with concrete fascia and earth retaining structures.” Crews will also install CIDH piles, abutments, and columns. Within UP’s right of way, crews will grade and prepare the site before constructing “support of excavation systems, [building] roadway structural sections, and [constructing] a temporary track detour to allow trains to remain operational through the construction zone.” Work on the sidewalks, curbs, and gutters is also included in the contract.
The second $56 million contract is for the Alondra Park Multi-Benefit Stormwater Capture project. This contract seeks to remove contaminants from stormwater runoff. According to the release, “OHLA will also revitalize the existing park – located above the capture reservoir – with new soccer and multi-purpose turf fields, in addition to two rehabilitated baseball fields.” Project work includes excavation to remove 265,000 cubic yards of soil, “placement of precast concrete for the underground storage chambers, installation of stormwater pipes, valves, and pretreatment filtration equipment, and the construction of diversion, junction, and manhole structures.” Construction for capturing stormwater will take place 30 feet underneath the park, and “the team will upgrade recreational spaces and ball fields and plant native and drought-tolerant vegetation and trees, bioswales, and permeable pavements.”
