It may not be official yet, but it sure looks like summer has come to the city.

With a hot and steamy weekend forecast, there are lots of festivals to enjoy.

There are also a few things you should know about getting around the city, whether it's by transit or by car.

TTC disruption

The Yonge-University Line 1 subway will be shut down from St. George Station to Sheppard West Station.

The TTC says crews are performing train testing ahead of the fall launch of phase one of the new Automatic Train Control signal system.

Shuttle buses are running between Sheppard West and Lawrence West stations and there will be additional service on nine east-west bus routes in the closure area to ease travel to the University-Spadina Line. 

Because of construction around Eglinton West, St. Clair West and Dupont stations, there will be no shuttle service to and from those stations. 

"It might add 10 to 15 minutes to a traditional subway ride, but that is much less time that it would take if we had used traditional shuttle service," TTC spokesperson Stuart Green said 

This is the seventh of 11 closures on this portion of the Yonge-University Line this year. 

"Most weekends in the summer, you will see subway closures," Green said.

Green said it is important for them to use weekends to do repair work because overnight periods are not long enough to get work done. 

Street closures

Street festivals, including Taste of Little Italy and the Much Music Video Awards, will be contributing to travel disruptions this weekend. 

College Street will be closed in both directions between Bathurst and Shaw Streets for the Taste of Little Italy from 6 p.m. Friday through to 3 a.m. Monday.

Palmerston Boulevard, Clinton Street and Montrose Avenue north of College Street, will also be closed for the same period. 

The Much Music Video Awards will cause street closures in the area bound by Richmond Street in the south, Queen Street in the north, Simcoe Street in the east and Peter Street in the west. 

The TTC will be diverting bus routes on these roads. 

The Village Festival will close Church Street between Wood and Gloucester streets from Saturday at 9 a.m. to Monday June 19 at 2 a.m.

Similarly, the Flavours of Fairbanks festival will close Eglinton Avenue between Dufferin Street and Ronald Avenue from 2 a.m. Friday to 4 a.m. Monday morning.

Thrill of the Grill on Danforth will close the avenue between Broadview and Playters avenues on Saturday from 7 a.m. to 6 p.m.

On Sunday, the Journey to Conquer Cancer 5 km run will close University Avenue between Bloor and Wellington streets from 8 a.m. to noon.

The TTC urges people looking for more details about how road closures will affect routes and schedules to check www.ttc.ca before heading out.
