Hardenburgh, Ulster County

The Millbrook Covered bridge, also known as the Grant Mills Covered Bridge, was originally constructed in 1902 by Edgar Marks, his son Orrin Marks and Wesley Alton. Bridge construction, assisted by local craftsman, took place over the course of nearly seven months, opening to traffic on December 8, 1902.
The town lattice truss bridge is approximately 17 feet wide and 69 feet long as it crosses the Mill Brook. The bridge is located in the town of Hardenburgh in Ulster County, less than a ½ mile from the border with Delaware County. The single lane bridge is closed to vehicular traffic. The Millbrook Covered Bridge is listed on the National Register of Historic Places.

“The Millbrook valley has long been known as one of the beauty spots of the Catskills, if not the entire state. Residents of the area should make a “get acquainted” trip over this road some day this summer. Go over the Barkaboom or Beech hill mountain, then up the Beaverkill and back to the Millbrook valley by Cross mountain. Folks will never believe there is such breath taking beauty till once they have seen it.
