City of Bakersfield’s Westside Parkway, Phases 1-6, Thomas Road Improvement Program

City of Bakersfield’s Westside Parkway, Phases 1-6, Thomas Road Improvement Program: Phase 1 was the $28 million Mohawk Street Extension – a new six-lane alignment with three bridges one each over the BNSF Railroad, future State Route 58 Interchange, and the Kern River; and MSE walls. The City of Bakersfield subsequently retained the team to administer the remaining project segments through what is known as Phase 6A, and then the second portion of Phase 6 (Phase 6B), which is just beginning. The six project phases amounts to $150 million in construction contracts and entails the construction of 18 bridges consisting of slab, pre-cast girder, and cast-in-place prestress box girder design; dozens of mechanically stabilized earth (MSE) and Type 1 retaining walls; more than 4 miles of masonry block sound walls on CIDH foundations; 3,000 linear feet of cast-in-place box culverts ranging in size from double to quadruple barrel; a large storm drain pump plant; and the City of Bakersfield’s second largest sewer lift station. When completed, the Westside Parkway (future State Route 58) will extend from Truxtun Avenue, just west of State Route 99 to Allen Road and will incorporate five new interchanges. Our services have included contract administration, construction inspection, scheduling, oversight of construction staking and materials sampling and testing, constructability reviews, utility relocation, and permit compliance monitoring.
