More about Dunn Memorial Bridge...
The Dunn Memorial Bridge, officially known as the Private Parker F. Dunn Memorial Bridge, carries US 9 and US 20 across the Hudson River between Albany, New York and Rensselaer, New York. Completed in 1967 to replace an earlier span bearing the same name, the highway bridge has a steel girder design. It is the southernmost toll-free road crossing of the Hudson. It is named for Parker F. Dunn, an Albany native who was posthumously awarded the Medal of Honor for his service in World War I.
While traveling eastbound on the Dunn Memorial Bridge towards the City of Rensselaer, there is a noticeable stub where the road ends and traffic is "forced off" the bridge onto offramps for US Routes 9 and 20. The road was originally supposed to continue on as part of the canceled South Mall Expressway to Interstate 90 at present day Exit 8.
Rensselaer's Riverfront Park is located under the eastern end of the bridge. Peregrine falcons have been observed nesting under the roadway since 1998, and the New York State Department of Environmental Conservation set up a webcam to monitor them.
