Before taking off this weekend to go anywhere in the city, commuters should be aware of a couple of closures that may shift their plans.

Line 1 is closing from St. Clair West subway station to Union for signal upgrades on Saturday and Sunday. Shuttle buses will be running between Spadina and St. Clair West.

St. Clair West, Spadina, St. George, St. Andrew and Union stations will all be open for the sale of fares and for connections to surface vehicles, but all other stations will be closed.

Some streetcars will be diverted by maintenance work along King St. and the Harbourfront tunnel as well.

If you’re thinking that driving might be more worth it in the face of such a closure, you should know that driving may not be easy this weekend either.

The Don Valley Parkway is closing at 11 p.m. on Friday for annual maintenance, and will not reopen again until 5 a.m. Monday. The closure was meant to happen last weekend, but had to be moved due to the weather.

Crews will be tackling a number of repair and inspection projects, such as patching asphalt, cleaning bridge joints and catch basins, repairing guard rails and performing sign maintenance, according to a news release put out by the city.

Alternate roads that could be used are Don Mills Rd., Bayview Ave., Victoria Park Ave., and Kingston Rd.
