Steady progress is the byword for the ongoing upgrade and rehabilitation of the Sweetwater River Bridge in Chula Vista, a $25.7 mil-

lion project (total cost) along the I805 in the South Bay area of San Diego County that is a joint-project between the California Department of Transportation and the San Diego Association of Governments (SANDAG).

The bridge and safety improvements are part of the I-805 South Express Lanes Projects, which cover more than 11 mi. between East Palomar Street in Chula Vista and the I-805/SR 15 interchange. Flatiron West Inc. was awarded

a $17 million construction contract to upgrade the 534-ft.-long bridge (five lanes in each direction, including an HOV lane) between Bonita Road in Chula Vista and SR 54 in National City. see BRIDGE page 36

Modular, prefabricated bridge designs have proven to be a critical component of accelerated bridge construction (ABC). The FHWA favors the ABC bridge construction technique especially in the design of highway bridges that feature varied spans, skew angles and construction materials. Prefab’s contributions to the ABC process has earned it a place at the state and city transportation levels, as well.

Research has shown that ABC techniques expedite construction of bridges through shortened project duration, lower material costs, less personnel and increased safety on the job site. Technology such as Geosynthetic Reinforced Soil-Integrated Bridge Systems (GRS-IBS), Slide-In Bridge Construction (SIBC) and Prefabricated Bridge Elements and Systems (PBES) are major components of these ramped-up techniques. High-performance materials used in prefabrication of bridge elements enhances the entire

construction operation. Their integration is expected to significantly improve the condition of the United States bridge network, increase the life-span of bridges and minimize the need for maintenance and repair, according to FHWA research.
