Motorists in Petaluma will face delays next week around Sonoma-Marin Area Rail Transit commuter rail tracks as crews extend their work south from Santa Rosa.

The right southbound lane of Lakeville Street between East D and East Washington streets will be closed Monday through Friday for track construction.

The East D Street rail crossing, meanwhile, will be closed from 6 a.m. on Monday through 7 p.m. on Sunday, May 5. SMART will offer temporary access to Hopper/Lakeville Street businesses on a temporary road from eastbound D Street.

The projects are part of the effort to establish commuter rail service from Santa Rosa to San Rafael. Trains are expected to start as early as 2015.
