A $63 million project will add a museum and performing arts center to the site of the 1969 Woodstock Music Festival. The first construction phase of the Bethel Woods Arts Center includes a 4,800-seat pavilion, a museum and events gallery, permanent outdoor sheds, parking, infrastructure, and landscaping. Plans for a 650-seat community theater are slated for phase two. The pavilion will be supported by glue-laminated, engineered timber supports, and was designed by Westlake Reed Leskosky of Cleveland. Boston-based Suffolk Construction is the general contractor, and Clough Harbor & Associates of Albany, N.Y., is the civil engineer. The Olin Partnership of Philadelphia is the landscape architect.
