Construction is set to begin on Monday, June 27 at night between 8 pm and 6 am to remove and replace nine grates along Mission Street, beginning between 24th and 25th.
The grates have reached the end of their useful lives and create noise and travel hazards in their current condition. In order to improve the safety of the grates for the travelling public, provide easier access for BART Maintenance Crews, and minimize noise to the local community, the steel grates, frames and concrete collars will be replaced with more robust features for an extended lifespan.
BART apologized in advance, for the work will be noisy as it lift the old grate, make repairs, install the new grate, and pour the concrete collars. Each grate will take two to three weeks to replace, and BART expects the project to be completed by fall 2016.
Mission Street will be open to vehicular traffic and MUNI service for the duration of the repairs during the day. After the night shift, the contractor will place steel plates over the open enclosure until the grate can be fully BART appreciates its riders understanding - and please excuse the light and noise - while BART carries out this important work and build a Better BART.
