The Bay Bridge's westbound upper deck reopened a day and a half ahead of schedule.
With all planned demolition and maintenance work completed, California Department of Transportation Officials began removing cones from the bridge and approaches around 7 p.m. Traffic was flowing freely by 7:30 p.m.
Motorists passing through the toll plaza are asked to drive carefully, since the merge will be different. While 20 lanes will still merge down to 5, they will curve slightly to the south, Ney said.
The bridge was not scheduled to reopen until Tuesday at 5 a.m., but Ney said unexpectedly good weather had allowed work to progress quickly.
"The next time we plan to close the Bay Bridge will be to open the new Bay Bridge, Labor Day weekend 2013," Ney said.
Traffic slowed to a crawl on the Golden Gate Bridge Saturday night as people tried to find a new way to get into the City.
The bridge saw heavy evening traffic and anticipates approximately a 50 percent increase in traffic levels this holiday weekend, spokeswoman Mary Currie said today.
Construction crews working on the westbound lanes of the Bay Bridge set to work and quickly finished the task.
Crews started letting cars pass into San Francisco from the East Bay at about 7 p.m. on Sunday evening. The span was slated to reopen at 5 a.m. Tuesday.
