Niska Road bridge to be closed February 28 until further notice

Guelph, Ont., February 13, 2017—The City is closing Niska Road bridge to all traffic—drivers, pedestrians and cyclists—beginning February 28. The City is closing the bridge indefinitely due to safety concerns about the bridge’s condition and the unstable effects high spring water flows and heavy rainfall can have on the bridge’s main support structures (abutments).

We’ve been able to prolong the life of bridge by completing various repairs since a 2013 report indicated the bridge was failing,” noted Kealy Dedman, City Engineer. “At this point however, the condition of the abutments combined with coming spring and summer river flows pose too big a risk for us to keep the bridge open.

Pedestrians and cyclists are at as high a risk as drivers because the nature of the deterioration is structural. High or fast flowing water can further damage or deteriorate the bridge’s support structures.

A 2013 report from an external engineering consultant indicated that the bridge was nearing the end of its useful life and would need rehabilitation or replacement within three to five years. In 2016 the City increased external engineering consultant inspections to twice a year, with City staff checking the condition of the bridge monthly. Bridge inspection reports filed by the external engineering consultant in 2016 estimated the bridge’s remaining service life at about one year.

The original bridge crossing the Speed River collapsed in 1974. That bridge was replaced by the Bailey bridge, loaned from the Ontario Ministry of Transportation, as a temporary solution.

The current bridge was never intended as a permanent crossing here,” said Dedman. “Bailey bridges were not built to last, and we’re really seeing the effects of long-term use on this one, especially with the abutments being right in the water course.”

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 made to address 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.

Next steps yet to be determined:

The City is waiting on a decision from the Ministry of the Environment and Climate Change regarding Part II Order requests filed in response to the City’s Notice of Study Completion of the Environmental Assessment before deciding on next steps for the bridge. A permanent solution for the bridge will decided once the City receives the Ministry’s response.

Our decision to close the bridge is in the best interest of community safety,” said Dedman. “Once we receive direction from the Ministry, we can decide how to best proceed with the deteriorating bridge.”

  1. If it is that dangerous or unstable why would it not be closed right now rather then wait to month’s end? With milder weather on the horizon and probably releases from Guelph Lake combined with other runoff, is the City willing to accept the liability should a vehicle or pedestrian tragedy occur?

  2. Could it not still be open for people walking? I understand vehicles but people and bikes like the bridge by the youth centre. I hope you and staff will consider.

  4. Great news! Now the lovely river lands can be restored. An independent engineer said the bridge could be easily repaired for pedestrians and cyclists. Save the city $6 million and save the environment and the landscape. Cars have lots of other choices.

  5. if the bridge is unsafe Why are no inspection reports posted since October 2016? This is now February it defies belief that 18 wheel transport trucks can still illegally use this so called unsafe bridge until the end of the month but not pedestrians or bikes after Feb. 28. The City claimed during the EA process that the bridge was unsafe but no efforts were made to make it safer for bikes or pedestrians. Other single lane bridges have traffic lights or stop and yield signs. According to the CTV story there are now 5000 vehicles using Niska, a narrow local width road with steep hills and poor site lines instead of Wellington 124 and the Hanlon which were built to carry higher volumes of traffic and cost millions to build. Guelph claims to be a city “that makes a difference” but appears it only wants to make a difference for commuters to save them a difference in their travel time of a few minutes, all at the expense of the safety of local residents especially children and the wildlife using the regional wildlife corridor along the river. When the bridge is closed take a few minutes to walk to the river and enjoy the peace and quiet of our Hanlon Creek Conservation lands. Take the time share our vision of a quiet river park, a place of refuge in a very busy traffic congested city. This is why so many people oppose the 2 lane bridge.

      • And of course liability with the warm temps and runoff and their possible effects on the bridge supports. But why wait as I had said do it now!!

    • If the bridge is so unsafe, shouldn’t it be closed immediately? In the past few days most of the snow has melted and we had a huge thunder storm tonight with lots of rain (Friday, February 24th, 2017) … very large trucks are still barreling over the bridge … I’m just not understanding how the bridge can be safe for vehicles that clearly exceed the weight restriction of the bridge up until February 28th, 2017 … but on March 1st, 2017 a pedestrian crossing the bridge could be at risk. I’m not an engineer, but can you please explain this to me. Thank you.

      • Sandy,
        Engineers are concerned with upcoming spring thaw and its impact on the abutments. Giving a heads up to community is respectful in my opinion. Obviously if it was critical immediately at present it would closed.

    • Steve: Just reviewed Cam’s rules for proper engagement in his blog between himself and the public. Thought this might help for it looks like you have may forgotten or haven’t read this part of his blog.

      Rule #2: be respectful. I want my blog to be a place for honest debates and tough conversations, free from name-calling or attacks.

      Just remember that your point and opinion is weakened once you start name calling. Keep in mind that Cam is the first Mayor to open up through social media and work hard at being fully transparent to the public. You don’t have to agree with city hall’s decisions (some act like Cam works alone down at city hall), however, Cam’s efforts should be commended and he should be treated with respect.
