The '''Dunn Memorial Bridge''', officially known and dedicated as the '''Private Parker F. Dunn Memorial Bridge''', carries [[U.S. Route 9 in New York|U.S. Route 9]] (US 9), and [[U.S. Route 20 in New York|U.S. Route 20]] (US 20), across the upper [[Hudson River]] between [[Albany, New York]] and [[Rensselaer, New York]].

==Description==
Third highway / road bridge crossing the upper Hudson River at this site since 1882, 1933 and currently 1969. Current span constructed 1967-1969 and completed in 1969 to replace earlier parallel smaller / narrower span with an extensive steel girder superstructure framework above the roadbed, built 1931-1933, with a center section which opened to allow passing barges and boats to pass through, was dedicated bearing the same name, and memory of PFC [[Parker F. Dunn]] (1890-1918).

An earlier crossing of the Hudson at this same site was constructed in 1882, also of steel girders but with older technology of additional wrought iron superstructure trusses above the roadbed and the wood plank roadbed for horse-drawn carriages, wagons and single horse-back or pedestrian traffic stretching level straight across the tops and resting / bolted on several supporting stone piers. Known as the old  Albany-Greenbush Bridge, it existed from about 1882 to 1933,

Historical black & white photographs of all three bridges spanning the upper Hudson are scanned from the library / archives ("morgue") on the internet website of the longtime local daily newspaper ''[[Times Union (Albany)|Albany Times Union]]'' in [[Albany, New York]]

The current 1969 arching highway bridge has a [[Girder bridge|steel girder]] design supporting  underneath the roadbed deck, resting / bolted onto the tops of reinforced steel bars framework imbedded in poured concrete piers anchored in the riverbed bottom. The bridge superstructure road deck arches up high enough off the normal river water surface to allow passing river boat / barge traffic without a center-section opening span piece. It is the southernmost toll-free road crossing of the upper [[Hudson River]]

Both two of the most recent Hudson River spans of 1933 and 1969, were named and dedicated for Private first class  [[Parker F. Dunn]] (August 1890-October 1918), of the [[United States Army]], an Albany native who was posthumously awarded the congressional [[Medal of Honor]] for his service, bravery and sacrifice in the [[World War I|First World War]].(1914/1917-1918), killed in the last year and last weeks of the four-years long "Great War" on the [[Western Front of World War I|Western Front]] in northern [[France]] of [[Europe]] fighting the invading / attacking [[Imperial German Army]] of the [[German Empire]] ([[Germany]]). He was unfortunately killed in an incident that would cause him to be posthumously awarded the Nation's highest and rarest military decoration only two weeks before the peace / truce signed in the famous railway car in the [[Forest of Compiegne]] of France, between the western [[Allies of World War I|Allies]] and the enemy [[Central Powers]] of the [[Armistice of 11 November 1918]].

The 1882 Albany-Greenbush Bridge also parallel and the later 1931-1933 old bridge which was the first of two to carry Private Dunn's name was kept up for a few years after its [[1960s]] successor opened, but was eventually demolished (and many steel girders recycled) by 1971.

While traveling eastbound on the Dunn Memorial Bridge towards the City of Rensselaer, New York, there is a noticeable stub where the road ends and traffic is "forced off" the bridge onto off-ramps for [[United States Route 9|U.S. Route 9]] and [[United States Route 20|U.S. Route 20]]. The road was originally supposed to continue on as part of the canceled [[South Mall Expressway]] to [[Interstate 90 in New York|Interstate 90]] at the present-day Exit 8.

Rensselaer's Riverfront Park is located under the eastern end of the Dunn Memorial Bridge. Wildlife of  [[Peregrine falcon]]s have been observed nesting under the roadway since about 1998, and the [[New York State Department of Environmental Conservation]] set up a [[webcam]] (video / television monitoring camera system) to broadcast its signal on the internet, to monitor and protect them.<ref>{{cite web| url = http://www.dec.ny.gov/animals/7429.html| url-status = dead| archive-url = https://web.archive.org/web/20070518044708/http://www.dec.ny.gov/animals/7429.html| archive-date = 2007-05-18| title = Peregrine Falcon Webcam - Albany, NY - NYS Dept. of Environmental Conservation}}</ref>

On July 27, 2005, the bridge was temporarily closed when a ramp leading to the [[Empire State Plaza]] split vertically, causing the roadbed to drop more than a foot. A section of the ramp, which at {{convert|89|ft|m}} tall is the uppermost one connecting to the bridge, had slipped and come to rest on a concrete supporting pier. The [[New York State Department of Transportation|Department of Transportation]] was alerted to the situation by a call from a commuter who had driven over the gap. Two steel towers were installed to support the ramp and it was later repaired.<ref>{{cite news| date = July 28, 2005| url = http://www.bizjournals.com/albany/stories/2005/07/25/daily41.html| url-status = dead| archive-url = https://web.archive.org/web/20110525133326/http://www.bizjournals.com/albany/stories/2005/07/25/daily41.html| archive-date = 2011-05-25| title = Engineers search for cause of ramp buckle on Dunn Memorial Bridge| newspaper = [[The Business Review (Albany)]] }}</ref><ref>{{cite news |date=July 2005 |title=Damage shuts down Dunn Memorial Bridge |work=[[WNYT (TV)]] |url=http://www.wnyt.com/x4483.xml?ag=x156&sb=x183 }}{{Dead link|date=February 2022|bot=InternetArchiveBot|fix-attempted=yes}}</ref>

An unfortunate incident occurred on March 25, 2014, a man jumped off the bridge following a police chase in connection with a shooting the previous night. The man survived and was evacuated via ambulance.<ref>{{cite news|last=Gardinier|first=Bob|title=Car hits bridge; suspect jumps|url=http://www.timesunion.com/local/article/Two-men-jump-off-Dunn-bridge-after-police-chase-5350998.php#photo-6077997|access-date=27 March 2014|newspaper=[[Times Union (Albany)]]|date=26 March 2014 }}</ref>
