TTC riders will face some interruptions Sunday with a partial closure on the Yonge-University line.

Trains won't be running between Bloor-Yonge and Eglinton stations because crews are installing new track lines at St. Clair Station.

During the closure, shuttle buses will be running between the stations.

According to the TTC, the buses will be "frequent and accessible."

TTC spokesman Brad Ross said the buses will arrive at each station every two to three minutes.

People can board the buses on the street at all stations except Eglinton, where buses will enter the station.

Regular subway service is scheduled to resume Monday morning.

Road closures

Meanwhile, motorists will have to contend with several road closures due to weekend events or road work.

The city is asking drivers to avoid the areas, if possible, or to give themselves extra travel time.

Two events will result in road closures Sunday.

Church Street will be off-limits to motorists between Alexander and Gloucester streets for the Church Street Village Fair. The closure will be in effect between 8 a.m. to Monday at 1 a.m. Wellesley Street will remain open.

A series of road closures will take place to accommodate the Acura 10-Miler & 5K race.

The closures are bounded by Eastern Avenue to the north, Parliament Street to the west, Commissioners Street to the south and Leslie Street to the east.

They will be in effect between 6:30 a.m. and 2 p.m.

Until Oct. 8, the off-ramp from Highway 401's westbound lanes to Islington Avenue's northbound and southbound lanes is closed for construction.
