FREMONT (KCBS) – A new BART station that is expected to ease traffic congestion on Interstate 880 could be open for service sometime in October.

This nearly five-and-a-half mile extension is key because it paves the way for a future line to San Jose.

BART spokesperson Alicia Trost said the Warm Springs/South Fremont Station could be open before Halloween. However some issues have to be resolved first.

“There’s reports in newspapers this morning of a possible date of October 22nd, and it’s just not clear yet if that is going to be the date,” Trost told KCBS. “Because there is a lot of work that needs to take place, before we know, absolutely 100 percent we’re certain that we’ll have what’s called revenue service on that day.”

This project was first proposed back in 1991 so postponing the opening by a few days may not matter too much.

“We’re confident it can happen in fall. Hopeful towards the end of October, but a couple of things need to be checked off the list before we can absolutely set an opening date,” the BART spokesperson said.

Testing and critical cable work must be done before that familiar train whistle blows.

The Warm Springs station would be the latest system extension since the Millbrae/SFO extension was opened in 2003. It would also be the newest station since the Oakland International Airport station was opened on BART’s separate, automated line in 2014.
