Second BART tunnel under bay gets renewed attention

SAN FRANCISCO (AP) - With the San Francisco Bay Area economy booming, a plan to build a second tube for BART trains under San Francisco Bay is getting renewed attention.

San Francisco Mayor Ed Lee said last month he planned to begin a regional conversation about another Transbay Tube.

BART trains currently only have one tunnel under the bay, creating delays when a train stalls or other problems arise. Supporters tell the San Francisco Chronicle a second tube would allow BART to offer 24-hour service and increase the system's capacity.

Still, almost no one expects a second tube to become a reality anytime soon. The cost - estimated to be as high as $12 billion - is one major obstacle. A second tube would also have to satisfy environmental concerns.
