At the Belmont Avenue Grade Separation, crews recently completed the abutment wall on the west side of the overpass. Abutment walls are part of the substructure of a bridge, including overpasses, and provide vertical and lateral support from the superstructure to the foundation. These walls also act as retaining walls by retaining embankment that will be placed in the future. Crews have also completed a few columns and are now working on the bent cap. A bent cap is an intermediate support that sits on top of a group of piles to help disperse lateral and vertical loads. The bent cap supports the girders and transfers loads to the bent columns. To the east, crews are working on several utility relocations including relocating PG&E, water and storm drains.
