The trolley tunnel will close down tonight at 10 p.m. and reopen at 5 a.m. on Monday, SEPTA has announced. The closure is due to maintenance of overhead wires and will impact all routes.

Routes 11, 13, 34, and 36 will divert to 40th and Market Streets and Route 10 will divert to 40th and Filbert Streets.

This closure is not related to the annual “Tunnel Blitz,” which was recently postponed due to the recent problems with Septa’s Regional Rail cars.
