Between 2008 and the end of 2010, six New York City bridges will turn 100 years old, and the newly formed New York City Bridge Centennial Commission will be making sure they're adequately feted. The six centennial spans are the Madison Avenue, Manhattan, Borden Avenue, Pelham Bay, University Heights and Queensboro bridges.
The celebrations were announced this morning by Deputy Mayor Edward Skyler and other officials at Tramway Park the base of the Queensboro Bridge. Events will include exhibitions of original designs, rare tours of the historic bridges, "bike-boat-walking tours," and other festivities for each bridge as they hit the 100 mark. We take a close look at the six birthday bridges below.

The University Heights Bridge spans the Harlem River from West 207th Street in Inwood to West Fordham Road in the University Heights section of the Bronx. The current bridge opened on January 8, 1908 and cost $1,182,782; as the old Broadway Bridge was being replaced, it was floated downstream and recycled as the University Heights Bridge, which became the first "green" bridge! The swing span was replaced by a new one in 1992. (Photo: jag9889.)





what about roebling's erection?
Thanks to the Madison Ave bridge I can walk from Harlem to the Bronx and catch the 4/5. I'm gonna party hard for its birthday in '10.
If by Roebling's erection you mean the Brooklyn Bridge, the centenary celebration of that span was held in 1983 and featured a wonderful fireworks exhibition over the bridge.
Nearly-Happy Birthday,Manhattan bridge!
Oh, and it's not really known yet if Cloverfield's monster was in fact an alien. And it was only the big on that smack-downed the Brooklyn Bridge.
Good point, Kingpin. Duly noted.
The Manhattan Bridge is a beautiful Bridge, but I've seen it tilt and sway every time a train goes over. That can't be normal. No wonder so much constant maintenance has to be done.

"...was designed and built by Polish bridge engineer Ralph Modjeski with the deflection cables designed by Leon Moisseiff, who later designed the infamous Tacoma Narrows Bridge in 1940."
Those Wacky Polish Engineers. They crack me up.
