Bay Bridge Forward Project Marks First Conversion of General-Purpose Lane<\/p>\n

SAN FRANCISCO, April 14, 2026 \/PRNewswire\/ —\u00a0The Metropolitan Transportation Commission (MTC) today announced that construction work will begin next week on a six-month project to convert the far-left lane of westbound Interstate 580 to a high-occupancy vehicle (HOV) lane from just east of the Piedmont Avenue undercrossing in Oakland to the start of the existing westbound carpool lane near the foot of the MacArthur Maze.<\/p>\n

The 2.3-mile project \u2014 undertaken in partnership with Caltrans and the Alameda County Transportation Commission \u2014 marks the Bay Area’s first conversion of a general-purpose lane to a carpool lane. This is a key element of MTC’s Bay Bridge Forward<\/a> initiative to fund comparatively low-cost capital projects to help move more people in fewer cars through the Bay Bridge corridor; speed travel times and improve schedule reliability for bus riders; and reduce greenhouse gas emissions.<\/p>\n

Beginning next Monday, April 20, drivers headed westbound on I-580 can expect to see crews installing concrete K-rails to protect workers and equipment from moving traffic. Because most work will take place during the overnight hours, drivers can expect night-time lane closures over the next few months. Once the project is completed this fall, use of the left lane in this segment of westbound I-580 will be restricted to buses and other vehicles with three or more occupants on weekdays from 5 a.m. to 10 a.m. and from 3 p.m. to 7 p.m.<\/p>\n

MTC is the transportation planning, financing and coordinating agency for the nine-county San Francisco Bay Area.<\/p>\n
