A Facebook post circulating Cedar Rapids claims a popular bridge isn't safe to drive.

But the city says that's not the case, and the bridge is completely safe. And it's warning people of circling scares on social media.

Bridges across Cedar Rapids are built to last anywhere from 80 to 100 years. The bridge along 16th Avenue Southwest was built in 1984.

"This bridge is in good structural shape," City Engineer Nathan Kampman said.

Every two years, the city inspects its roughly 60 bridges.

The latest report of the 16th Avenue bridge happened April 2015.

"It is not structural deficient," Kampman said.

Despite this inspection, some don't believe this bridge is safe.

A social media post states, "I guess the city of Cedar Rapids is gonna wait till it falls and kills someone before they decide to fix it". And circles two gaps on the bridge.

But city engineers say these gaps are proof the bridge is doing its job.

"These expansion joints are there and part of the design of the bridge and allows the bridge to expand as the concrete heats up and cools down," Kampman said.

While the Facebook post has nearly 300 shares, many drivers in town aren't worried. Traffic still flowed regularly on the bridge today.

"It's pretty safe to drive," Jose Vega said.

And the city says if drivers notice any abnormalities in bridges, they should contact public works. This feedback can help give guidance for what bridges need updates, even if it's simply for cosmetic reasons.

"That's why we do design maintenance on it every once in awhile," Kampman said.

With the goal this bridge lasts the city at least another 50 years.

The bridge's next inspection will come sometime in early spring or late summer.
