The Carroll Street Bridge in Gowanus Is Reopening in June (original) (raw)

Are drawbridges the most entertaining pieces of infrastructure around? They evoke medieval moats, tall sailboats, Inspector Clouseau. The only time you might not appreciate them is when the one you want to cross is in the up position — or, in the case of the Carroll Street Bridge, pulled back. Built in 1889 over the Gowanus Canal, it’s a retractile bridge, one that slides into place like a pullout table leaf instead of flipping up and down. It’s an old-fashioned and comparatively rare design. (There appear to be just two operable ones left in America, the other being the Borden Avenue Bridge in Queens.) And this one is an official city landmark. After nearly five years’ closure and reconstruction, it will reopen on Monday, and I visited this week as it rolled open and closed for a test.
It will officially go back into service on Monday, June 15, with a change that’s until now gone unannounced: The bridge will henceforth be restricted to bicycle and pedestrian traffic, plus emergency vehicles. Paul Schwartz, the Department of Transportation’s deputy commissioner in the Department of Bridges, explained that the new rules reflect the changing neighborhood around the upper end of the canal, one where industry and heavy trucks have to a great extent given way to condos and the strollers they bring. Banning cars from the bridge won’t disrupt much: Before the closure, this was the most lightly trafficked span under Department of Transportation control, carrying about 1,000 vehicles a day. It will move much less frequently than it did back in the factory days because there’s so much less shipping on the canal now; a DOT representative tells me it was opened about once a week before the closure. These days, you (“you” in this case being a ship’s captain) are asked to call ahead to make sure someone’s there to open the bridge.

It’s seen significant repairs twice in semi-recent memory: once in the 1980s, when it was in such bad shape that it couldn’t move at all, and again after Hurricane Sandy did its damage. Although the bridge’s frame is steel, a significant amount of the structure is built of wood, and it therefore needs periodic attention. Schwartz explained to me that this time around, the understructure of the bridge was rebuilt but (owing to the Landmarks designation) had to maintain its late-19th-century appearance. Behind the wooden facings of the abutments now lie concrete and steel pilings with a 50-year design life. Wooden piles, Schwartz tells me, used to have a decent lifespan in the harbor because the water was so toxic that even the critters that eat wood couldn’t survive. As the water got cleaner, the marine borers known as teredos, the termites of the sea, came back — “not just here but all over the city” — and started nibbling away at them. Above the water line, the timber parts of the bridge (most visibly the road surface) are all new, and the steelwork got some repairs and fresh paint. The Belgian-block paving at each end has been relaid as well.
The test opening-and-shutting this week went exactly as it was supposed to, and it’s fun to watch. A loud horn blast alerts everyone nearby a short time before the deck starts to move, to avoid one of those Clouseau moments. It sits on railcar-style wheel assemblies, which roll on steel rails, and an electric motor in the control house — formerly a steam engine; Schwartz told me it was converted in 1908 — drives a steel cable, about as thick as a meaty thumb, that winds around a pair of pulleys and pulls the bridge back or forth. The whole business takes maybe three or four minutes. Then the horn sounds again. The movement is smooth and slow, barely perceptible unless you’re paying close attention. As the bridge finished up its trip, I had to double-check the pulley to see if it, and we, had stopped.

One thing that didn’t change is the enameled sign overhead reading “Any Person Driving Over This Bridge Faster Than a Walk Will be Subject to a Penalty of Five Dollars for Each Offence.” It looks ancient, although it’s actually a 1980s addition, re-created from turn-of-the-20th-century photos like the one seen above.
