The detour at Route 53 in Redding will come to an end on Friday afternoon. When the state Department of Transportation closed the road at Umpawaug Road, the work was slated to wrap up Tuesday. The weather cooperated for the most part, but there was a slight delay. The bridge carries traffic over a brook and was built in 1928. A 21-foot section was rebuilt so that there can be 12-foot travel lanes and 4 foot shoulders in each direction. Some other minor safety improvements were also completed. There will be some alternating one way traffic through mid-September for minor work including tree replanting.
