Lyn Road Overpass Rehabilitation

R.W Tomlinson Limited would like to advise all stakeholders and emergency service providers that construction will soon begin on Highway 401 bridge rehabilitations at Lyn Road as well as directly on Lyn Road underneath the structure. The work is expected to begin on Tuesday, August 16, 2022 and will continue until the end of November 2022. Traffic can expect the following interruptions:

  • Single lane closures and shoulder closures on Highway 401 in both Eastbound and Westbound Lanes can be expected throughout construction.
  • All Lanes on the 401 will be opened to traffic on weekends, however, traffic control closures will resume on Monday mornings.
  • Additional to the 401, a single lane closure will be implemented on Lyn Road and the area will be controlled with Temporary Traffic Control Signals. Lyn Road is expected to have both lanes open as of October 6th, 2022. Emergency Services will be given the right of way when passing through this lane closure if required.

All consideration has been given to implement traffic control measures to ensure minimal disruption to the traveling public. We apologize in advance for this inconvenience and appreciate your cooperation during construction.
