BART and its lead contractor PrōVen Management have completed installation of the critical components for the major track replacement project that’s been underway near the Orinda Station since April. Because of this earlier completion BART is cancelling the last scheduled track shutdown weekend between the Lafayette and Rockridge stations. The final shutdown weekend had been scheduled for July 4-5 but instead BART will run regular service between Lafayette and Rockridge that weekend.
BART crews worked around-the-clock on previous shutdown weekends to replace critical trackway components. In many cases those components dated back to when BART first started service on the Yellow Line through Contra Costa County back in 1973. Project accomplishments include:
- Replaced four mainline track switches that were at the end of their useful lives. These large track components can measure up to 200 feet in length and allow trains to move from line to line.
- Installed approximately 3,000 feet of new rail.
- Replaced 1.200 tons of rock ballast, which is essential for stabilizing the trackway.
- Replaced platform edge tiles at the Orinda Station.
The result of this work is a more comfortable and reliable trip through Orinda for BART riders as well as a quieter BART experience for neighbors.
BART rebuilding a priority during stay-at-home
BART is making the most of this time with extremely low ridership and the new 9 pm service closure to advance rebuilding projects across the system. A priority has been placed on how critical projects are to the core mission of providing reliable train service.
The earlier closing time has allowed downtown San Francisco electrical cable replacement work to start at 9 pm on some weeknights. Since March 23, workers have pulled 23,000 feet of 34.5kV cable and installed 3,000 feet of conduit to protect the new cable. Six months of Sunday single tracking in downtown San Francisco are eliminated for every six weeks BART can single track at 9 pm on weeknights.
Other projects being advanced include the 19th Street Station Modernization, El Cerrito Del Norte Station Modernization, rail grinding to reduce noise, and transbay tube cathodic protection
Capital projects are supported by multiple funding sources including Measure RR, which was approved by BART District voters in 2016 and provides $3.5 billion in funding for infrastructure work.
Next big track rebuild to begin in July in Hayward
The next major track replacement project is scheduled to begin the weekend of July 18-19 in Hayward. Between July and September, BART crews will replace and rebuild a nearly 50-year-old interlocking and other critical track components just south of the Hayward Station.
The work is expected to require five weekend track shutdowns between the Bay Fair and South Hayward stations. Free buses will replace trains on those weekends and riders can expect delays of 20-40 minutes. The track shutdown weekends are scheduled to be July 18-19, August 1-2, August 22-23, September 5-7 (Labor Day weekend), and September 19-20.
