Revised Concrete Cure Times Reduce Duration of Bridge Closures

July 27, 2023

After repairing a concrete bridge deck, the Michigan Department of Transportation’s policy requires waiting nearly a month for the concrete to cure before it can be treated and the bridge reopened to traffic. But new MDOT research shows the concrete may be ready sooner than previously thought. As each day of closure can cost thousands of dollars in construction and traffic management costs, reopening sooner can save significantly.
