City of Delano’s State Route 99 Woollomes Avenue Bridge Widening and Interchange Reconstruction

NV5 provided full suite construction management services for the $4.4 million State Route 99/Woollomes Avenue Interchange widening project, which entailed bridge widening, reconstruction of the on- and off-ramps, and improvements to local streets. A four-stage construction and traffic handling plan was implemented during construction, including a full freeway closure and detour during the setting of the pre-cast girders. Construction involved utility relocations, bridge and roadway construction, and new traffic signals. Services included resident engineering, structure representative, and construction inspection; SWPPP inspection; contract administration; scheduling; oversight of construction staking and materials sampling and testing; and coordination with utility companies, UPRR, Caltrans Oversight, and permitting agencies.
