When traffic flows across the new stretch of the San Francisco-Oakland Bay Bridge for the first time, it will do so nearly a quarter-century after a deadly earthquake during the 1989 World Series collapsed two 50-foot sections of the old structure.

The 6.9-magnitude Loma Prieta quake hit just as millions tuned in to watch Game 3 of the "Bay Bridge World Series" between the Oakland Athletics and San Francisco Giants, killing 63 people and causing billions in damage.

The Bay Bridge failure prompted one of the costliest public works projects in state history.

Next week, the $6.4 billion project finally opens to traffic after decades of political bickering, engineering challenges and billions in cost overruns. The new bridge is scheduled to open by 5 a.m. Tuesday at the latest.
