Jackson's Sawmill Covered Bridge

The Jackson's Sawmill Covered Bridge or Eichelberger's Covered Bridge is a covered bridge that spans the West Branch of the Octoraro Creek in Lancaster County, Pennsylvania, United States. A county-owned and maintained bridge, its official designation is the West Octoraro #1 Bridge. The bridge is purportedly the only covered bridge in the county that is not built perpendicular to the stream it crosses due to the placement of the sawmill on one side of the bridge and the rock formations faced by the builders on the other side.

The bridge has a single span, wooden, double Burr arch trusses design with the addition of steel hanger rods. The deck is made from oak planks. 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.

The bridge's WGCB Number is 38-36-33. In 1980 it was added to the National Register of Historic Places as structure number 80003520, but it was removed from the Register in 1986 It is located at 39°53′49.2″N 76°4′48″W / 39.897°N 76.08°W / 39.897; -76.08 (39.89700, -76.08000). The bridge lies in Bart Township, 3.25 mi (5.2 km) to the east of Quarryville and 1.5 mi (2.4 km) south of Pennsylvania Route 372 on Mt Pleasant Road. Due to its remote location in an isolated part of the county, it is seen less than many of the county's other covered bridges that are closer to the major populations centers such as Lancaster.
