The 1878 Weaver's Mill Covered Bridge is a covered bridge that spans the Conestoga River in Lancaster County, Pennsylvania. The 85-foot-long, 15-foot-wide bridge was built in 1878 by B. C. Carter and J. F. Stauffer for $1468.

The old sawmill on the nearby farm is now used as a chicken house. Nearby Amish use this bridge extensively for their horse-drawn buggies. It is also known as Isaac Shearer's Mill Bridge and was at one time called White Hall Mill Bridge.

The bridge has a single-span, wooden, double Burr arch trusses design with the addition of steel hanger rods. It is painted red, the traditional color of Lancaster County covered bridges, on both the inside and outside. Both approaches to the bridge are painted in the traditional white color.

Length of largest span: 80.1 ft.
Total length: 82 ft.
Deck width: 13.1 ft.
Vertical clearance above deck: 11.5 ft.

Of the 1,500 covered bridges that once stood in the state of Pennsylvania, as of 2019, approximately 200 remain.
