The current Brandywine Valley tourist brochure, this describes and locates 12 bridges, two of which are not in the county but nearby.
Dating from 1964, this brochure describes the 17 covered bridges still in existence then, and includes a map that shows the location of each bridge.
In 2014 the New London Area Historical Society, the PennMaryDel Questers, and the Franklin Township Historical Commission sponsored a talk by Ray McKay on "The Covered Bridges in Chester County" at the New London Academy on March 11th. A former Chester County school teacher, Mr. McKay researched Chester County's covered bridges after his retirement. Mr. McKay also on occasion gave tours of Chester County's surviving covered bridges, and handed out his driving directions for the tour at the talk. The directions are available as a PDF file if you wish to visit the bridges on your own.
