BAYONNE BRIDGE, FROM OVER STATEN ISLAND LOOKING NORTH - Bayonne Bridge, Spanning Kill Van Kull between Bayonne & Staten Island, Bayonne, Hudson County, NJ
The deck on this bridge has been raised 64' to allow super-panmax ships to access container terminals on the other side. They are also having to dredge a deeper channel, 51'-57' depending on the stage of the tide. The 2000' wide Ambrose Channel starts twelve miles out in the ocean. It was built in 1931 with a clearance of 151'. In the mid 20th Century, the Port Authority predicted that the superstructure of ships in the future would top 190'. Pieces of the roadway over the water were removed by lowering them onto barges. The new channel was tested with a new container ship, CMA CGM Theodore Roosevelt, that is 1200'x158'x52.5' and can hold 14,414 containers. The previous maximum capacity was 9,400 containers. That ship stopped at other east coast ports before it docked at NYC. That would reduce its draft to below 51'. In fact, it was just 40.85'. This ship went under the Bayonne Bridge on Sept. 7, 2017. The wheelhouse on this ship was at the same height as the old roadway. "According to Port Authority statistics from a few years ago, seven million vehicles cross the Bayonne every year. About a hundred and three million vehicles use the George Washington." The bridge won't be finished until 2019. [NewYorker, pay count of 4. Some of the article talks about how dangerous the Kill Van Kull strait is to navigate because of tides coming in from both sides and a sharp turn in the shipping channel. The article also discusses Ammann, who was the designer of this and several other major bridges, and the harbor and sea pilots.]

The Kill Van Kull is one of the world's busiest shipping channels, connecting the ports of Newark and Upper New York bays with other ports around the world.

[Look at the list of the derrick boat.]

[This shows the temporary piers or falsework and the temporary support above the second pier so that they can cantilever the remainder of the arch and avoid putting a pier in the navigation channel.]

[I didn't realize that the navigation channel was so far off-center until I saw this image.]

[Given the stone encasement of the abutments, this is obviously a concept illustration. Like the towers of his George Washington Bridge, Ammann obviously intended for the steel work to be covered by stonework. But the depression happened before the bridges were completed, so the stone work, which was purely decorative, was skipped. Some people have argued that the raw strength of the towers looks better without a stone facade.]
A street view catches the original steel girder approach spans and the new precast segmented partial approach spans. Before they can finish the new piers and approach spans, they need to remove the old roadway. After the second part of the new piers are built, they can remove the yellow pipes.
[I saved an image because this catches the phase where the new deck is full width, but the approaches can't be finished because the old deck still exists.]

(new window) Among other things, this video animates how a travelling gantry installs the precast segments for the new approach spans.
This container terminal doesn't care about the height of the Bayonne Bridge. But these are the terminals I found that do care: New York Container Terminal, APM Terminals (can handle ships in both Newark Bay and Elizabeth Channel), and Port Elizabeth Terminal Corporation.
While looking for container terminals, I found these two RoRos (Roll-On, Roll-Off) in dock. Since I've never seen one with their ramp out, I wanted to capture this image.
