California ? A highway ramp shut down by the collapse of an overpass near the San Francisco-Oakland Bay Bridge won’t have to be rebuilt from scratch and could reopen within 10 days, the governor said Wednesday.

The ramp connecting two interstate highways was blocked Sunday morning when a burning tanker truck brought down the overpass. Crews finished clearing debris from the collapse Tuesday.

Gov. Arnold Schwarzenegger said the ramp connecting westbound Interstate 80 to southbound Interstate 880 could be fully open to traffic in as little as seven days and as many as 10.

“Progress on repairing the collapsed freeway connectors is moving at lightning speed,” he said.

Investigators found that the steel girders holding up the lower ramp had warped but remained structurally sound and could be straightened, California Department of Transportation spokesman Bob Haus said.
