Plaza at 16th & Mission Station closed for resurfacing and cleaning 9/10-21
Starting on Monday, September 10, crews will be power blasting the 16th and Mission Street Station plaza in San Francisco using compressed water and ground glass (as opposed to sand which contains crystalline silica and has been found to be hazardous to employees).
This process will thoroughly clean the asphalt before it is resurfaced with a material called Thermoplast. Thermoplast will be easier to clean as it repels liquids, rather than absorbing them as the current asphalt does.
Half of the plaza will be closed at a time, so at no time will access to the station be restricted. Once the first half along 16th Street is complete, the second half bordering Mission will be closed.
The entire project should take approximately two weeks with full reopening scheduled for September 21, 2018. This is part of ongoing efforts to improve the rider experience in and around this busy station.
