Who wouldn't want to come downtown this weekend?

The Raptors begin their playoff run against the Pacers at the ACC on Saturday afternoon and after a chilly spring, the weather will be flat-out stunning: sunny, with daily highs in the double digits (including 18 C on Sunday).

But a few travel issues, including a shutdown of the Don Valley Parkway and a section of the TTC's Line 1, means it won't all be happiness and hoops.

DVP weekend shutdown starts Friday night at 11 p.m.

First, the DVP.

It will be closed to all traffic between the Gardiner Expressway and Highway 401 from 11 p.m. Friday to 5 a.m. Monday. Why? This is the city's annual spring cleaning and maintenance of the elevated highway. Crews use the time to perform routine maintenance, everything from filling potholes and repainting road lines to clearing clogged catch basins and adjusting traffic cameras.

As alternative routes into downtown, drivers can use Don Mills Road, Bayview Avenue, Victoria Park Avenue and Kingston Road. But those roads could get congested quite quickly, especially ahead of Saturday's Raptors game, so expect delays and consider moving up your departure time.

Oh and heads up: a similar closure is coming on the May 13 weekend.

A city news release announcing the DVP closure suggests those heading to downtown this weekend "consider using public transit as a convenient alternative to driving" which is almost funny when you consider that a chunk of the TTC's Line 1 (Yonge-University-Spadina) subway line will also be closed this weekend. More on that below.

The TTC will run shuttle buses between Lawrence West and St. George stations on Line 1 this weekend. The closure will allow crews to update subway signal systems. (TTC)

TTC to close section of Line 1 for signal work.

There will be no subway service between St. George and Lawrence West stations on Saturday and Sunday as the TTC continues to upgrade its antiquated signal system. All trains will turn back southbound at St George Station and northbound at Lawrence West Station. Shuttle buses will be operating between the affected stations, with the following exceptions:

Glencairn Station will be closed: board shuttle buses at Bathurst Street and Glencairn Avenue.

Eglinton West Station will be open: board shuttle buses at Bathurst Street and Eglinton Avenue West.

St Clair West Station will be open: board shuttle buses at Bathurst Street and St Clair West Avenue.

Line 2 subway won't start until 12 noon on Sunday

Subway service will start at noon between Pape and St. George stations on Sunday due to bridge work on the Prince Edward Viaduct. All trains on the Bloor-Danforth line will turn back westbound at St. George Station and eastbound at Pape Station.

During this closure, shuttle buses will stop at all stations.

Wheel-Trans buses will operate between Pape and St. George stations upon request. Customers can request the Wheel-Trans bus by speaking with a supervisor at these stations.

Union Pearson Express weekend shutdowns

Work to replace three spans on the rail bridge over Lansdowne Avenue will also affect service on the Union Pearson Express airport train this weekend, starting Friday.

Here's how it will break down:

Friday: Service will run normally (every 15 minutes) until 6:45 p.m. when service will be suspended. Bus service will be available between Pearson airport and Union Station every 30 minutes for the price of a UPX fare.

Saturday: UPX trains will run every 30 minutes starting at 5:30 a.m. until just after 1 p.m. From 2 p.m. to 1 a.m. UPX service is suspended but buses will run between Union and the airport every 30 minutes.

Sunday: UPX is service suspended from 5:30 a.m. o 11 a.m. After 11 a.m., the UPX will run every 30 minutes.

Note that during the shutdowns, there will be no service for UPX passengers who board trains at Bloor West or Weston stations.
