Henry Hudson Parkway, but in 1994, the New York State Department of Transportation added a Jersey barrier to block off access to the driveway. The driveway continued down through the massively arched structure known as the Billings Arcade. The arcade features five 50-foot tall arches constructed of Maine granite. On top of the arcade is a small open area known as the Billings Lawn. The arcade cost $250,000 to construct, . Concession building The park's concession building is located north of Margaret Corbin Circle, on the western side of Corbin Drive. The two-story stone structure is located in a slope. It contains a hip roof made of slate and open pavilions on all sides except the southern facade. The building's main entrance is through an arcade with three arches on the eastern facade. Originally, the building contained a cafe with refreshments, as well as restrooms and the headquarters for park staff. The building, having fallen into disrepair, was closed after a fire in 1976. It was restored beginning in 1995 by Bette Midler's nonprofit organization NYRP. The organization was awarded the operation of the concession in 2000, and opened the New Leaf Café – later called the New Leaf Restaurant and Bar – the next year. NYC Parks closed the building for necessary roof repairs in December 2014, and NYRP announced that it would not reopen, due to the length of time the repairs would take and the increased rent that the organization would have to pay. The operation of the restaurant was taken over in late April 2015 by Coffeed, a Queens-based cafe which donates a portion of its revenue to local charities. The restaurant closed again in January 2020 after Coffeed's contract expired. Other structures The Shelter Overlook, an octagonal gazebo, is located east of Corbin Drive at the northeast corner of Sir William's Dog Run. It originally contained a tile roof, later replaced with a slate roof after a fire. The roof is supported by stone piers. The gazebo is frequented by those using the dog run. A two-story brick ventilation building for the subway is also located within the park at Broadway and Dongan Place. There are also two comfort stations in the park. The first is a structure at Broadway and Sherman Avenue that looks like a cottage, while the second is located inside a slope north of the Cloisters. Wildlife Cabrini Woods hosts 80
