Created by the Union Forge Heritage Association in 2010, the Taylor Steelworkers Historic Greenway traverses several of the most historically significant properties in the Borough of High Bridge and the State of New Jersey. It is dedicated to the memory of the working men and women of the Union Iron Works and the Taylor Wharton Iron and Steel Company. Founded in 1742, the iron works is the oldest foundry in the history of the United States. The 7 Mile Greenway Trail passes through and connects historic High Bridge properties including the TISCO Complex, the Union Forge, the Solitude Estate, Lake Solitude, Nassau Acres, and Springside Farm. These borough open spaces contain state and nationally recognized historic structures with ties to America's Colonial past. The lands were farmed, lived on, and traveled by the native Lenape and by later Americans during the Colonial Era, Revolutionary War, and beyond. The route preserves industrial and agricultural properties where Patriots forged cannon balls, while also honoring the many immigrants who came to call the area home and labored there. The greenway also passes through varied forest habitats and around Lake Solitude, where species including bald eagles, belted kingfishers, great blue herons, gulls, and mergansers thrive.
