Bridge 24-WG

Background Summary
The bridge was built circa 1922 and has reached the end of its service life. The bridge was closed due to severe structural deterioration in July 2018. CIMA was retained to do a Class B EA that began in Nov 2018 and was completed in Jan 2020. The EA determined that the preferred solution is to replace the bridge with a single span two lane concrete girder bridge.
At the Council meeting on June 29, 2020, Council directed that the Heritage Centre Wellington Committee be consulted on the sympathetic design and commemorative strategy for the replacement of the Bridge 24-WG. Staff met with the Heritage Committee on Oct 12, 2021 to present examples of commemorative plaques and options for an arch impression in the concrete parapet walls of the replacement bridge. The Heritage Committee advised of their preferred Option 5 (see below) on Nov 15, 2021.

As shown on the map above, bridge 24-WG is located on the First Line between Sideroad 10 and Sideroad 15 in the rural area north of Fergus. Bridge 24-WG crosses the Irvine Creek in the former Township of West Garafraxa.

In Feb 2021 the detailed design and contract administration for Bridge 24-WG was awarded to Triton with approval of Council. The consulting team is currently in the process of preparing the detailed design drawings and specifications and submitting permit applications to the GRCA, DFO, MNRF and Transport Canada. An online Public Information Centre will be held in December 2021 to give information on the features of the bridge design and provide an opportunity for public comments or questions. We anticipate issuing the bridge construction tender in late Feb 2022 to begin construction in June 2022.


The Project
The Township’s asset management plan shows that the replacement of Bridge 24-WG is currently in the top two highest priority bridges along with Bridge 16-WG which is currently in the EA phase. The bridge asset management plan considers the probability of the bridge failure as well as the consequences of the bridge failure to determine the highest priority bridges. The criteria for calculating the probability of bridge failure includes the bridge condition rating, the average daily traffic and if the bridge is load limited or closed. The variables to determine the consequences of the bridge failure include the increase in response time for emergency services, the detour length, the average daily traffic, the impact of closing the structure for local access, and the heritage status.

Bridge 24-WG is a top priority for replacement because it’s almost 100 years old, is in very poor condition and is at the end of its service life. Bridge 24-WG was closed to traffic in July 2018 due to severe structural deterioration and it was load limited and height limited for many years prior to that. The closing of Bridge 24-WG has cut off access along the First Line thereby creating a detour which has increased emergency response times and had a negative impact on local and agricultural access.

By replacing Bridge 24-WG on the First Line we will be establishing a route for future traffic for access from First Line into the new Fergus business park at the future Dickson Drive extension. This will allow vehicles to access the business park without increasing traffic volumes through the more urbanized areas of Fergus.

Replacing Bridge 24-WG and reopening the First Line will improve connectivity of the road network, eliminate the detour, improve access, and shorten response times for emergency services.

Bridge 24-WG was a single lane bridge that didn’t meet current safety standards. The new bridge will have improved safety measures with proper guard rails, concrete curbs, and paved asphalt shoulders. The new bridge will accommodate two lanes of vehicle traffic and provide a suitable crossing for large farm vehicles to support agricultural activity in the rural area to the north of Fergus.
