Its burr truss and board and batten siding are the features described as distinguishing it. The reviewers noted it was in fair condition and that the boundaries needed to be adjusted to encompass the abutments.","narrative":"Weaver's Mill Bridge is a covered bridge crossing Conestoga Creek in Caernarvon Township, near Churchtown in Lancaster County, Pennsylvania. Built in 1878 by the builder B. C. Carter, it has a Burr truss, a type of timber construction that combines arch and truss elements, and it rests on cut-stone abutments. The bridge is 85 feet long at the end post measurement. Its vertical board and batten siding and shingled gable roof give it the typical appearance of the county's covered bridges, and its simple triangular portals are also clad in board and batten. The bridge was part of a group of covered bridges in Lancaster County that were evaluated as examples of 19th-century timber frame construction. The bridge was in fair condition at the time, with its siding and roof needing repair. Reviewers noted that the boundaries needed adjustment to include the abutments fully.","period_of_significance":null,"architect_builder":"B. C.
