As part of our ongoing flood mitigation strategy, infrastructure improvements are being made to the Centre Street Bridge. In November of 2018, a flood gate was installed on the south side of the bridge. Permanent dikes have been constructed on either side of the Centre Street Bridge that protect the level of river flows seen in the 2013 flood, plus one additional metre.
About the Flood Gate
A variety of different design options were considered and evaluated. Two options were presented at the May 23, 2017 regular meeting of council and the decision was made to move forward with a sliding gate option that is concealed within the dikes when not in use.
The projected final total cost of the Flood Gate is approx. $2.8 million, and the project is fully funded through the Alberta Community Resilience Program (ACRP) from the Government of Alberta and Long-Term Recovery Support (LTRS).
Previous requests for Centre Street Bridge funding were for between $40 million and approximately $80 million (depending on the number of lanes, secondary causeway, and inclusion of the Lineham Bridge replacement).
While the Alberta Government has been extremely supportive of the Town’s recovery efforts, and provided a significant amount of funding, these requests for funds were turned down.
The Town’s priority is to protect the town, its residents and infrastructure. Therefore, the Flood Gate was installed as an immediate solution before further pursuing a new bridge. The Flood Gate has an expected life span of 20 years and the Town will soon be completing work to extend the life of the existing bridge by reconditioning the rails, adding new bearings, and replacing the deck.
Every Spring, the flood gate is tested in preparation for flood season. During the test, the Town will look for any parts of the gate that didn’t fair well over the winter months, plus fine tune each of their roles and responsibilities by running training exercises during the test. Spring tests will be announced to the public so they are aware of any closures and/or detours.
