Some pedestrians in Saskatoon are getting worried about the walkway under the Circle Drive Bridge. But is there anything to be concerned about?

Lloyd Litwin is a geophysics technician for the University of Saskatchewan. He was doing work in the area, and didn't like what he saw on the pedestrian walkway. "I had never been on this bridge, and I decided to have a quick peek and had a look, and as a technical minded person, I notice details. The first thing I saw was all of these missing bolts up there."

Litwin saw several missing bolts from the structure's supports. Most had fallen and now sit building up rust. It's likely a problem that has been happening for some time.

"It's obvious there's some structural problem here, winter freezing, who knows, vibrations from the big trucks," says Litwin. "I don't know what the problem is but when they're missing on both sides, 75 per cent of them have failed in one connector, I figure somebody ought to know about this."

But is it the start of a major structural problem or is it something that can be easily fixed? Gaylen Heinrichs, a city engineer, says the problem is a small one. "They are the supports that hold the bridge in a stable manner without moving too much, so a few of those have apparently come out, but it's not a situation where there's a problem with the weighting of the bridge or the bridge not being structurally sound."

Heinrichs says the city has been in contact with the bridge's engineers to get the bolts back on, but says it's not an easy job.

"It's not like you can just move over and bolt them back where they belong, because they're over top of the river, and so that's something we're looking at trying to get fixed," says Heinrichs.

City engineers say this is not a safety concern. Still, Litwin believes everything is connected for a reason, and he doesn't plan to visit the walkway again anytime soon.
