摘要

San Francisco and the Golden Gate Bridge are inextricably linked in the minds of tourists, but to many a commuter across San Francisco Bay, the most significant fixed crossing in the area is the San Francisco-Oakland Bay Bridge, popularly known as the Bay Bridge. It was this bridge that was visibly damaged in 1989, when the Loma Prieta earthquake caused a 50-foot section of the upper roadway to fall onto the lower. A motorist who drove into the gap was killed, and the entire structure had to be closed to traffic while it was being repaired. The loss of the bridge, which carries Interstate 80 across the bay, emphasized the obvious—that the crossing is a vital link in the area's infrastructure, upon which the regional economy relies greatly. Uncommonly rapid repairs reopened the bridge in about a month, but damage and risk assessments made it clear that the entire structure had to be updated to make it more earthquake resistant. Thus began a saga of design and construction that, more than 15 years later, has yet to fully play out. In the meantime, because of the attention focused on the structure, the history of the Bay Bridge has rightfully regained a place of distinction in both public and professional memory.
