Covered Bridge Road at SR 3004, Hartley Township, Union County, PAMillmont Red Covered Bridge
Millmont Red Covered Bridge, also called the Millmont or Glen Iron Covered Bridge, crosses Penns Creek southwest of Millmont in Hartley Township, Union County, at Covered Bridge Road and SR 3004 (Creek Road). It is a Burr truss built in 1855. The National Register gives a length of 131 ft, which makes it the longest covered bridge in Union County, while dalejtravis.com lists 154 ft overall. It is closed to motor vehicles and open to foot traffic.
The bridge was built in 1855 and was listed on the National Register of Historic Places on February 8, 1980, as part of the Union County Covered Bridges group nomination. Uncoveringpa.com reports that it was closed in 1998 and did not reopen to traffic for 12 years, then closed to cars again in spring 2016 because of structural problems. Dalejtravis.com records a rebuild in 2010.
A Burr truss pairs a long timber arch on each side with a multiple kingpost truss, the two bolted together to share the load.
From PA 45 in Hartleton, dalejtravis.com routes visitors south on Laurel Road and Shirk Road, west on SR 3004 (Creek Road), then south onto Covered Bridge Road to the bridge. There is no parking along SR 3004, and uncoveringpa.com suggests parking on the south side of Penns Creek. The bridge is open to pedestrians only.
