About the closure
The City is closing the Niska Road bridge indefinitely due to safety concerns about the bridge’s condition and the unstable effects that high spring water flows and high rainfall events can have on the bridge’s main support structures (abutments).
City staff and contract engineers have been completing increased inspections of the bridge since a poor inspection report in 2013. These inspections are done to observe deterioration and determine the need for repairs to maintain safe travel conditions over the bridge.
Pedestrians and cyclists are at as high a risk as drivers because the nature of the deterioration is structural and not connected to the use of the bridge itself. High or fast water flows can damage or lead to deterioration of the bridge’s support structures.
The bridge was closed to replace deck boards in April 2015. These surface repairs allowed the City to keep the bridge open for almost two more years. These repairs were not aimed at addressing concerns about the long-term structural integrity of the bridge, which the City has continued to monitor. The structural issues cannot be addressed through repair and would require replacement of the abutments.
