The South Bay BART extension will change traffic patterns in North San Jose starting Monday--and the change will last for nine months.
The Berryessa neighborhood intersection of Sierra Road and Lundy Avenue, located just south of San Jose's main post office, will close for construction.
It will take nine months for crews to dig a trench under the streets, where the BART extension will go.
"Throughout the 10-mile extension, we either have the BART system running under roadways or over them," VTA spokeswoman Brandi Childress said. "In the northern area, we have more underground trenching, and as it ends at Berryessa, it goes into an aerial structure."
During construction, VTA Bus Line 77 will be rerouted to Flickinger avenue, which is the main detour route for this closure.
