Pictured below is the Prisoners of War Memorial Bridge, which carries the Providence & Worcester Railroad coming from northern Worcester over Central Street, next to the Medical Center, and over to Union Station.
A walk up Thomas Street will bring to the point where the picture on the right was taken. This is a view of the POW Bridge from the north end. The picture on the left is a close up view of the "tunnel," at the other end of which is Union Station.
