Mar 30, 2021  It’s also a time-saver. Bridge repair traditionally involves closing the structure and rerouting traffic. Workers arrive to remove the damaged portion before building forms to tie in rebar and pour concrete. It can take about 10 days for concrete to cure and gain strength. At this point, the bridge is tested under load before reopening.
