Temporary road closures for culvert replacements

The City of London will be undertaking culvert replacements this summer and into the fall which will mean temporary road closures as the work gets underway. This work is being done primarily in the southeast and southwest parts of the city.

The culvert replacement program will take place at the following locations and dates:

  • Westdel Bourne between Sharon Road and Longwoods Road - August 10 to August 14
  • Scotland Drive between Morrison Road and White Oak Road - August 31 to September 4
  • Scotland Drive between Old Victoria Road and Westchester Bourne (Middlesex County) - September 8 to September 12
  • Scotland Drive between Wellington Road South and Highbury Avenue South - September 21 to September 28
  • Scotland Drive between White Oak Road and Wellington Road South - September 28 to October 5
  • Sharon Road at Murray Road - October 5 to October 13
  • Westminster Drive between Highbury Avenue South and Old Victoria Road - October 19 to October 26

What is a culvert? 

A culvert is a structure that allows water to pass under or around infrastructure, such as a road or railroad. Culverts help prevent flooding, minimize erosion, and maintain roads in good condition longer.

Why is this happening now? 

Repairs and replacement in the near term are required to ensure structural integrity, address safety hazards, protect infrastructure from damage due to stream water fluctuation and precipitation runoff, prevent upstream flooding, and ensure compliance with environmental standards.

Transportation impacts

Drivers are advised to expect traffic delays if traveling in this area. Please follow the detour signage. Drivers should give themselves some extra time when traveling, use navigation apps to plan routes, and leave a little earlier to get to where they need to go.
