Sleep-deprived residents of the Duboce Park neighborhood have halted a Muni rail replacement project inside the Sunset Tunnel that aims to improve service on the busy N-Judah Metro line.
Neighbors living at the east end of the tunnel filed an appeal of the nighttime noise permit allowing contractors to work on Friday through Sunday nights, shutting down the months-long project until a hearing can be held on March 18.
“Man, it’s really loud,” said Bud Offermann, who lives on Duboce Street, near the eastern mouth of the tunnel and filed the appeal.
San Francisco Municipal Transportation Agency officials are hurriedly trying to work out a deal that will give neighbors some nighttime calm while allowing the work to proceed next weekend, Jan. 30 to Feb. 2.
