OTTAWA -- Ottawa motorists will need to find another route through Ottawa later this week due to a major closure on the Queensway for construction.

Highway 417 will be closed in both directions for 82 hours starting Thursday night, while crews replace bridges along Ottawa's busiest highway.

The City of Ottawa says the Queensway will be closed from 8 p.m. Thursday to 6 a.m. on Monday between Carling Avenue and Bronson Avenue. Crews will be demolishing and replacing the bridges over the Canadian Pacific Railway and Trillium Line O-Train tracks.

Here is a list of the Highway 417 ramp closures between July 2 and July 6.

  • O’Connor westbound
  • Lyon westbound
  • Bronson westbound
  • Rochester westbound
  • Parkdale westbound
  • Carling/Kirkwood eastbound
  • Parkdale eastbound

Orangeville Street will also be fully closed between Rochester Street and Booth Street.

In a media release, the Tomlinson Group said the bridge replacement work will generate excessive noise and traffic impacts during the period.
