​Bruce County council receives update on Walkerton bridge project

Bruce County council has received an update from Triton Engineering Services Limited, regarding the ongoing third-party review of the Durham Street Bridge in Walkerton.

Council heard that a recently-completed Bridge Condition Survey confirms that the existing bridge is generally structurally sound and “rehabilitation should be investigated as this could be a feasible and economical solution to extending the overall life of the bridge.”

As a result, rehabilitation alternatives will be added to the ongoing Schedule ‘C’ Environmental Assessment following the completion of the third-party review. Further consultations with a contractor that specializes in half-joint rehabilitation, suggest the work could be completed while maintaining one lane of traffic over the bridge.

A letter provided by sub-consultants Burgess Engineering, also recommends that heavy truck traffic, with the exception of municipal maintenance and fire and emergency vehicles, should be restricted from crossing the bridge and that an alternate truck route be established until rehabilitation/repairs are made to the bridge.

“A rehabilitation option could prove to be cost-effective and provide significant life-extending measures for the Durham Street Bridge,” said Adam Stanley, director of transportation and environmental services. “These alternatives would need to be investigated further and added to the ongoing Schedule ‘C’ Environmental Assessment following the completion of the third-party review.”

Triton Engineering has indicated the third-party review will be completed sometime in early March.

The transportation and environmental services department will be seeking to implement two alternate truck routes once agreements are reached with affected municipalities. These routes will facilitate the continued movement of truck traffic during the bridge weight restriction period on the Durham Street Bridge. Advanced warning signage for these routes will be placed strategically ahead of the bridge to divert heavy truck traffic from passing over the bridge.

The weight restriction would be a three-level load limit which differentiates various heavy truck types by the number of axles on the truck or trailers, and permits a maximum vehicle weight. The recommended weight restrictions would apply to vehicles greater than 15, 25, and 30 tonnes, with corresponding axles.

The Durham Street Bridge in Walkerton, which spans the Saugeen River along Bruce County Road 4, was constructed in 1937 and has served the community for 85 years.
