The structurally deficient Dorlans Mill Road Bridge over the east branch of the Brandywine Creek in East Brandywine and Upper Uwchlan townships, Chester County, will be closed and detoured beginning Monday, June 23, for the replacement of the bridge deck and beams. The bridge is expected to reopen in mid-September.

“The upcoming improvement of the Dolans Mill Road Bridge will provide motorists with a stronger and safer structure on which to travel over the Brandywine Creek,” District Lester C. Toaso said.

Dorlans Mill Road will be closed to through traffic between Route 282 (Creek Road) and Shelmire Road. A posted detour will take motorists over Route 282 (Creek Road) and Dowling Forge Road. Local access will be maintained up to the closure point. Motorists are advised to allow extra time when traveling through the area.

The two-span, steel I-beam bridge was built in 1931. It is 92 feet long and 20 feet wide. The bridge carries 3,215 vehicles a day.

PennDOT closed the bridge in October 2013 due to severe deterioration of four steel beams on the outside of the bridge. Three beams in the center of the span were determined to be safe to carry vehicular traffic.

The Dorlans Mill Road Bridge was reopened in December 2013 after crews created a single travel lane in the center of the bridge by installing delineators, painting traffic lines, and adding stop signs and stop bars. The bridge is posted with a 10-ton weight restriction.

Road-Con, Inc. of West Chester, Chester County, is the general contractor on the $400,000 project, which is financed with 100 percent state funds. When construction is completed, the bridge will no longer be categorized as structurally deficient and will no longer have a posted weight limit.
