OAKLAND -- Construction crews working at the Oakland Army Base project in West Oakland knocked over a pole, causing a small natural gas line to break Tuesday afternoon, authorities said.

It was the second time Tuesday that a gas line had ruptured in the city. It took more than three hours for PG&E crews to fix a rupture in an underground gas line at Golf Links Road and Fontaine Street in East Oakland that occurred about 8:25 a.m. and sent flames shooting up through cracks in the roadway.

Tuesday afternoon's mishap happened about 1:30 p.m. on Maritime Street near Burma Road.

Brandi Ehlers, a PG&E spokeswoman, said a private construction crew knocked over a pole which severed a three-eighths stainless steel above ground gas line that leads from an underground transmission line to a presssure recording device.

She said the leak was fixed about 2:45 p.m.

No flames were seen but there was a strong smell of gas, authorities said.

No injuries were reported.

No evacuations were done and streets that had been shut down were reopened soon after the leak was fixed.

The Oakland Army Base project is a $500 million redevelopment effort to transform the former base site into a logistics and warehouse center for the Port of Oakland.
