The Metropolitan Transportation Commission approved the allocation of $19 million in bridge toll funds Wednesday for the BART extension project in east Contra Costa County, MTC spokesman John Goodwin said.
Construction on the $462 million project began in October and is being done in conjunction with a project to widen state Highway 4. The tracks for the BART extension, known as eBART, will be installed in the highway's median.
It is scheduled to be open to the public in 2015.
"This is a good project, no question, especially given the growth in east county," Goodwin said.
