A Colorado Springs lab is testing the strength of the concrete on the new Cimarron Bridge. So far, it's not strong enough.
The bridge is scheduled to open Thursday, but not unless the concrete can pass a stress test Wednesday. Concrete was poured on the bridge about two weeks ago and the same mixture was also poured into cylinders. On the 7th, 12th and 14th days after the pour, those cylinders are put under pressure to see when they will crack.
Monday, the 12th day, some of the concrete cylinders cracked too early which means the bridge isn't quite ready yet.
The concrete will be tested again Wednesday. If it passes the test, the bridge will open up to traffic as scheduled Thursday.
