The City of Brockville says that the Hallecks Road 401 bridge is set to be demolished over the course of two evenings this week, on Friday, Apr. 21 and Saturday, Apr. 22, 2023.

The demolition comes as the bridge nears the end of its service life.

During this time, the City says, the 401 will be re-routed via an Emergency Detour Route (EDR) through downtown Brockville, from Long Beach to North Augusta Road on and off ramps.

The detour will be two consecutive nights, allowing one night for each direction on the 401.

The detour plan, which can be found here, will bisect the City at King Street and make crossing King Street difficult for residents and emergency services, the City says.

As a result, the City is requesting that the public refrain from parking on King Street on April 21 and 22 of 2023, between 10pm and 10am each night.

“Some barriers and detours may be set in place. Overnight parking on King Street during time, may result in vehicles being ticketed and/or towed,” the City says.

The exact planned bypass timing is as follows:

  • April 21, 2023 – Westbound bridge structure. All Westbound 401 traffic will exit at North Augusta, move south to King St. then west to Long Beach on-ramp
  • April 22, 2023 – Eastbound bridge structure. All Eastbound 401 traffic will exit at Long Beach, move east along King St. then North to rejoin the 401
  • In both cases the time will be 10:00 PM the evening of until 10:00 AM the following morning

The City says that staff, including Brockville Police Services and Brockville Police Department, “are working closely with the Ministry of Transportation to mitigate issues and provide safety measures for the public with as little disruption as possible.”
