PHILADELPHIA (CBS) – SEPTA is alerting commuters to the closing of the trolley tunnel which services trolleys on the Routes 11, 13, 34 and 36 lines.

SEPTA’s Heather Redfern says the trolley tunnel will close at 10 o’clock tonight.

“SEPTA’s closing the trolley tunnel that runs through Center City from 13th and Juniper down through the 45th Street Portal. And the trolley tunnel will be closed until 5 a.m. Monday August 12th so that we can do major power construction work during that time.”

Redfern says the closing will allow for some much-needed repairs.

“This is giving us a chance to do a lot of projects at one shot, and the majority of that work is replacing approximately ten thousand feet of worn overhead wire, and 25-hundred feet of the assembly system which attaches the overhead to the tunnel ceiling.” In addition, SEPTA will take this opportunity to do some work at Dilworth Plaza.

Redfern says during that time, trolleys will be diverted to 40th and Market Streets where trolley will start and end. She says passengers can transfer to the Market-Frankford subway line at 40th Street to get into Center City.
