The two historic covered bridges in Franklin County are both easily accessible while traveling the interstate and offer a great glimpse into the region’s history and the opportunity to see some of the rural beauty of the area.
Take a few minutes to read about these two historic bridges, and then take the time to visit them for yourself.
Martin’s Mill Covered Bridge
Martin’s Mill Covered Bridge is the most easterly of the two historic covered bridges in Franklin County, Pennsylvania. It is located next to Antrim Township Community Park near Greencastle and just a few miles north of the Maryland border.
Built in 1849, it utilizes the Town truss, which is rare in Pennsylvania outside of the covered bridges of Bucks County. The bridge was rebuilt after being destroyed by Hurricane Agnes in 1972 and raised five feet to help keep it from being destroyed by another flood.
It was completely refurbished again just a couple of years ago.
Today, the bridge is closed to traffic, but visitors are allowed to walk across it. It spans the Conococheague Creek and is 205 feet in length, making it the second-longest covered bridge in Pennsylvania.
Getting There: Martin’s Mill Covered Bridge is located near Greencastle Pennsylvania. It is a 10-minute drive off of Interstate 81. The bridge can be found at the following coordinates: 39.764884, -77.775690.
It is best to approach the bridge from the east off of East Weaver Road as there is no easy place to park on the western bank of the creek. Visitors can park in several locations in Antrim Township Community Park. If the park gate is closed, park along the road, but make sure not to block the gate.
Witherspoon Covered Bridge
Witherspoon Covered Bridge, called Red Bridge in some sources, is the more westerly over the historic covered bridges in Franklin County. Unlike Martin’s Mill Covered Bridge, cars are allowed to drive across this covered bridge.
Witherspoon Covered Bridge was built in 1883 and uses a Burr arch truss like most of PA’s covered bridges. It is 87 feet long and spans Licking Creek, just a few feet upstream of its confluence with the West Branch of the Conococheague Creek.
One highlight of visiting this bridge is the beautiful stone arch bridge located on the nearby Anderson Road. If you don’t drive over it, take some time to appreciate it by looking upstream on the West Branch of the Conococheague Creek from near Witherspoon Covered Bridge.
Getting There: Witherspoon Covered Bridge is located near Route 16, about halfway between Greencastle and Mercersburg. It can be found at the following coordinates: 39.787392, -77.854539.
There is space to pull a car off of the road on the northeastern side of the bridge.
