Foothill Boulevard Pedestrian and Cycling Bridge

Aufbau provided peer review of the construction drawings and project management and construction management support services for the project. Aufbau was engaged in every aspect of the project, from the preliminary conceptual design to final construction and project closeout.

The project entailed removal of East Upland Underpass Bridge (EUUB) – a steel through girder underpass structure formerly owned by Southern Pacific Railroad – which spanned over Foothill Boulevard (Route 66). EUUB was removed to accommodate the widening of Foothill Boulevard between Grove Avenue and Vineyard Avenue. The widened Foothill Boulevard added one lane of traffic and shoulders in each direction, a raised median island, and sidewalks – to widen Foothill Boulevard to six traffic lanes with a 14-ft median. The project constructed a two-span pedestrian/ cycling bridge along the alignment of the removed bridge which now carries the 7.5-mile Pacific Electric Trail over Foothill Boulevard. The new bridge is composed of reinforced concrete U-abutments at ends of the bridge and a center reinforced concrete column supported on a reinforced concrete pad footing. The superstructure consisted of cast in place post-tensioned reinforced concrete box girders. The artwork on the bridge depicted historic cars, states that Route 66 passed through and scenes from California and Illinois.
