PB designing Alameda highway improvement
The Alameda County Transportation Improvement Authority has awarded a US$110 million contract to Parsons Brinckerhoff (PB) to design a highway widening and improvement project along I-238. The improvements involve widening I-238 between I-580 in Castro Valley and I-880 in San Leandro from four lanes to six lanes in each direction. Auxiliary lanes will be added to I-880 between I-238 and West A Street. The project encompasses widening, reconstruction or replacement of 18 bridges. As the prime consultant, PB will be responsible for bridge design, construction staging, traffic handling, value engineering, permits, construction estimating and scheduling. Construction is scheduled to begin in the latter part of 2004 with completion slated for late 2006.
