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.
The 10-mile extension will take passengers from the Pittsburg/Bay Point BART station to Hillcrest Avenue in Antioch with a station in between at Railroad Avenue in Pittsburg, Goodwin said.
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.
