"SIGNIFICANCE: The 'skyway' was built as part of the transcontinental Lincoln Highway and was among the first limited access 'super highways' in the United States." Construction was 1924-32. [HAER-data] I thought the Lincoln Highway became US-30, which goes to Philadelphia. Evidently the Lincoln Highway continued East using today's US-1 route. The original highway did go out of its way to go through major cities. For example, it originally left Fort Wayne using what is now US-33 to go through Goshen, Elkhart, South Bend, etc. The US-30 that we see today across Indiana was built as a cutoff.

The skyway consists of cantilever bridges over the Passiac and Hackensack Rivers and this viaduct over South Kearny that connects those two bridges.

The skyway is around 3 miles long and the Hoboken Avenue Viaduct on the east side adds about another mile. The main span of each cantilevered bridge is 550' and has a 135' clearance. The skyway was part of a 13.2 mile extension of US-1 to feed the Holland Tunnel. It cost $20m. It would cost $3.2b to build it today. Instead of replacing it, NJDOT decided to spend $1b to rehabilitate it. Construction began in May 1923, and it was supposed to be completed in 1926. But "the extension was delayed by controversy over the routing through the New Jersey Meadowlands." That is why it was not done when the Holland Tunnel opened in 1927.

Because the power station in this photo has five instead of six smokestacks, this would be the Hackensack River Bridge.

| Metrotrails The Pulaski Skyway, completed in 1932, is a 3.5 mile bridge of combination deck truss cantilever and Pratt through truss designed by Sigvald Johannesson to span the Meadowlands and Passaic and Hackensack Rivers. It connects Newark and Jersey City. The span was named for Polish Nobleman and General Casimir Pulaski who helped bring order to the Continental Army during the American Revolution. David GoesslingThis is a fantastic book about the building of the Pulaski Skyway: https://thenewpress.com/books/last-three-miles A must-read for anyone interested in NJ history. |

| HistoricBridges Nathan Holth considers this to be the first fully limited access highway. Back then it was more commonly known as a superhighway. [This photo is old enough that the power plant has just three smoke stacks.] |
The two engineers that designed it had a background in railroads instead of highways. This was good because they knew how to design for a good traffic flow. Specifically, the importance of keeping the curves gentle and the grades low. [HistoricBridges] The S-curve in the Lake Shore Drive in Chicago demonstrates the nativity of highway designers with respect to the impact of curves on traffic flow.

Today, we take highway design concepts such as a median barrier, merge lanes and ramps on the outside instead of the inside for granted. But they had yet to be invented when this bridge was designed. Consequently, the skyway had a high accident rate when it opened. In fact, trucks were banned from the bridge because they had even an even bigger problem merging into traffic without a merge lane. [HistoricBridges, NYCroads]
The problem with ramps on the inside instead of the outside is that it causes one to merge into the faster lanes instead of the slower lanes. Chicago has examples of this on I-290 such as I-290 and Harlem Ave. (IL-43). Even with merge lanes, traffic on the highway gets screwed up when the ramps are in the center. If I remember correctly, I had trouble driving in Detroit because it also had some center ramps. And the signage did not help you figure out if you should be in the right lane or the left lane for an exit. And when a highway has 3 or 4 lanes, knowing which side to be on becomes rather important.
The center ramps allows us to get a good view of the truss members. As Nathan Holth commented on his Historic Bridges page, the trusses do not use the V-laced truss members that was the norm back then.

The Pulaski has been undergoing a lengthy and long-overdue rehabilitation. The rehabilitation funding was the source of a minor scandal, as the PANYNJ provided money to it under their mandate to provide funding to "Lincoln Tunnel approaches." This road leads to the Holland Tunnel, not the Lincoln.
ReplyDeleteI find the Pulaski fascinating, as its got a smooth Art Deco feel from a distance, while at the same time having an archaic complexity up close. The "covered roadway" approach from Hoboken is also fascinating - this has recently been reconstructed, and lost a litte of its decayed 1930's "charm." The western end where the NJ Turnpike threads under the Pulaski is also thrilling.
