Traffic delays will become more noticeable now that the Victoria Day weekend is over as Ottawa's construction season began in earnest Tuesday with a number of road closures.

Here's a look at a few of the changes that began today:

  • Belfast Road will be closed between Tremblay Road and Trainyards Drive
  • Elgin Street will be reduced to one lane in each direction from McLeod to Frank streets. The lanes will reopen by mid-July.

From Tuesday to May 25:

  • Lane reductions during off-peak hours begin Tuesday on Highway 417 between Kent Street and the Highway 417/174 split and between Parkdale Avenue and Rochester Street.
  • Hwy 174 westbound will also have off-peak lane reductions between Montreal and Blair roads.

From Tuesday until May 24, the following ramps will be closed nightly:

  • The southbound St. Laurent Boulevard on-ramp to Hwy. 417 eastbound.
  • The southbound Vanier Parkway on-ramp to Hwy 417 westbound.
  • The northbound St. Laurent Boulevard on-ramp to Hwy 417 westbound.
  • The southbound St. Laurent Boulevard on-ramp to Hwy 417 westbound.

The westbound Hwy 417 off-ramp to the Vanier Parkway will also be closed — from Wednesday, May 21 to Thursday, May 22.

The city said signs are in place to alert drivers. The city is asking residents to be flexible with commuting times and to consider walking, cycling and taking transit whenever possible.

Commuter Caitlyn McLaughlin said she tries to avoid construction altogether.

"I know that it's necessary but it's just I wish I knew more about where the construction was so that I could avoid it better and I always get surprised," said McLaughlin.
