Another weekend, another subway service disruption.

There won't be any service on Line 2 between Pape and St. George stations both Saturday and Sunday due to bridge work along the Prince Edward Viaduct, the TTC says.

Trains travelling from the west will turn back at St. George, while trains travelling from the east will turn back at Pape.

"During this closure, shuttle buses will stop at all stations," says a service notice on the TTC's website.

The transit agency is warning customers that Presto cards are not yet accepted on all shuttle buses, so passengers should carry tokens, tickets or cash as a back-up measure.

Wheel-Trans buses will also operate between Pape and St. George "upon request," the TTC says.

Chester Station will also be closed for the weekend, but all other stations will be open to purchase fares.

Meanwhile, the TTC "in coordination" with the city will temporarily restrict on-street parking on Danforth Avenue and Bloor Street to maintain traffic flow for shuttle buses and cars.

Parking will be restricted on:

both sides of Danforth Avenue between Pape and Broadview avenues.

both sides of Bloor Street between St. George Street and Avenue Road, between Church Street and Ted Rogers Way and between Huntley and Sherbourne streets.

The parking restrictions will be in effect between 3:30 a.m. Saturday and 12:01 a.m. Monday.
