Keller's Mill Covered Bridge

Keller's Mill Covered Bridge is a covered bridge that spans Cocalico Creek in Ephrata Township, Lancaster County in the U.S. state of Pennsylvania. A county-owned and maintained bridge, its official designation is the Cocalico #5 Bridge. It is also sometimes known as Guy Bard Covered Bridge (after a local jurist) and Rettew's Covered Bridge (after the person that Rettew's Road is named).

Due to heavy road traffic on the aging, one-lane bridge, construction on a new steel and concrete bridge to bypass the covered bridge occurred in the summer of 2006. According to Ephrata Township supervisor Clark Stauffer, the bridge has been disassembled and will be reassembled a few miles downstream to replace an existing one lane Mill Creek Road bridge. It was located at 40°10′11.4″N 76°12′16.8″W / 40.169833°N 76.204667°W / 40.169833; -76.204667 (40.16983, -76.20467) before being disassembled.


Keller's Mill Covered Bridge was originally built by Elias McMellen in 1873 at a cost of $2,075. After being swept away in flooding, the bridge was rebuilt in 1891, again by McMellen. It stayed there until it was disassembled and moved in 2006. The bridge was reopened on Middle Creek Road in December 2010.


Keller's Mill Covered 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. The bridge is the only all white bridge in the county, the only bridge to have survived the transition from whitewashing to the red color commonly used in barns throughout the county. The bridge is not painted on the inside.
