Bridge Management

Helping Connect the County

Lac Ste. Anne County is home to more than two hundred bridges of various size and structure. Compared to its municipal neighbours, the County manages a relatively large number of timber bridges. Care and maintenance of these structures fall under the purview of the Public Works Department.

Under the Municipal Government and Public Highways Acts, Municipalities must:

  • Maintain bridge structures for safety and maximize the economic service life
  • Construct new bridge structures to an appropriate standard

Bridge Asset Management Program

Lac Ste. Anne County's bridge inventory includes 217 Structures that are classified as follows:
• 72 Standard Bridges (Short Span Timber or Concrete bridges)
• 133 Bridge Sized Culverts (Barrel diameters > 1.5 meters.)
• 12 Major Bridges (including Steel Girder, long span Concrete or Truss Bridges)

A large number of bridges in the County are timber bridges, with a significant amount of these structures constructed between 1950 and 1960. The typical service life of a bridge is between 45 and 60 years.

Under the Municipal Government and Public Highways Act's, Municipalities must:
• Maintain bridge structures for safety and maximize the economic service life
• Construct new bridge structures to an appropriate standard

Based on the Service Life and the requirements under the Act's, it is projected that 50% of LSAC bridge structures need to be replaced or repaired within the next 10-15 years.

Lac Ste. Anne County's Annual Bridge Replacement Program includes upgrades, improvements and, where required, replacement to select bridge structures in the County.

Bridge Repairs

The County owns and maintains a total of 217 bridges. These structures are comprised of 72 short- span “standard” bridges, 133 bridge-sized culverts (culverts with a diameter of 1.5 m to 6.0 m), and 12 long-span “major” bridges. Until 2012, the County received significant Provincial grants to support the ongoing capital maintenance of its bridge infrastructure. Between 2012 and 2017, however, Lac Ste. Anne County received absolutely no provincial funding to support its bridge maintenance program. This lapse in funding caused severe maintenance deficiencies that eventually resulted in load restrictions and closed bridges.

In 2016, the County tendered and repaired seven bridges. Three critical bridges were opened to traffic at the end of December 2016, and the balance of the work was completed mid-March 2017. The total cost of this project was roughly $1 Million.

In 2017, the Provincial grant program was reintroduced as a competitive application program. Presently, however, grant funding amounts to just $37 million each year, and is intended for local road bridge maintenance projects across the entire province.

This same year, County Council adopted a long-range bridge infrastructure plan, which included 23 bridge projects at a cost of $3.3 million over the next ten years. The County retains a bridge engineering consultant to assess the condition of bridge structures. Based on inspections, priority projects are identified for major repairs or replacement and referred to in the capital budget.

In 2016, the County purchased two portable bridge structures to assist in maintaining transportation routes when bridges are undergoing major reconstruction. The 2016 capital included major repairs or reconstruction of 8 bridge structures. This $1.6 million expenditure in County infrastructure was funded in large part by the Federal Gas Tax Fund; a grant that provides predictable, long-term, stable funding that helps municipalities build and revitalize local public infrastructure while creating jobs and long term prosperity.
