1870 Ewalt/43rd Street and 1924,1991 Washington Crossing/40th Street Bridges over Allegheny River at Pittsburgh, PA

1870: (Archived Bridge Hunter; Satellite, south termination.)
1924: (Archived Bridge Hunter; Historic Bridges; HAER; HAER_drawingsPGHbridges; Satellite, 100 photos)

The Washington Crossing Bridge was finished in 1924. This 2,432' (741m) long bridge has a main span of 380' (116m). The 1991 rehabilitation retained "a relatively high level of historic integrity" [HistoricBridges] 
The vertical clearance is 180' (55m) at the center of the arches and 72.5' (22m) at the spring lines of the arches. [PGHbridges]

This was the 43rd Street Bridge in Pittsburgh, also known as the Ewalt Street Bridge. It was built in 1870 and connected Butler Plant Road in Millvale to 43rd Street (formerly Ewalt Street) in Lawrenceville. The bridge was demolished in 1924 and replaced with the Washington Crossing Bridge at 40th Street. The 43rd Street Bridge was the last covered bridge in Pittsburgh.

Dan Swartz: Knowing the location of the remaining retaining wall for this bridge and its height above normal pool I would say the river in this picture was at high flood level.

"Significance: The Washington Crossing Bridge is an outstanding example of a long-span metal deck arch bridge. Its unique architectural details, forged in a successful collaboration between architects and engineers in the design and construction of the bridge, add to its significance. The bridge is also significant because its construction was the culmination of a conflict over Allegheny River bridge heights between the U.S. War Department and local governments. The Washington Crossing Bridge was listed in the National Register of Historic Places in 1988." [HAER_data]

A true work of art. We're proud to be bringing this project to life for all of you.

It is 4,007.0 Feet (1221.3 Meters) long with a main span of 438.0 Feet (133.5 Meters).
"The Pattullo Bridge is an example of one of the more gracefully beautiful bridge types conceived, a steel trussed through arch."
[Note that the arch can be built without falsework.]

Construction started in 2020. [aecon]

"The new bridge will be built to allow for potential future expansion to six lanes." [PattulloBridgeReplacement_design] This webpage shows the selected design option. 

HistoricBridges has a downloadable archive of info about the new bridge. I looked at the file "Options Considered but not Pursued." They only considered a cable-stayed bridge design. The choices were about where to put the bridge and how to connect it to the existing streets.

Kiewit Corporation posted three photos with the comment:
Have you spotted Kiewit’s D.B. Patrick helping out around the new Pattullo Bridge site?  
The D.B. Patrick, a 303-ton heavy lift pile driver, is currently supporting the Pattullo Bridge Replacement Project in British Columbia, specifically assisting with the installation of steel girders for the north approach. This new four-lane cable-stayed bridge will improve connections between New Westminster and Surrey, providing wider lanes for both passenger and commercial vehicles, dedicated walking and cycling lanes, and enhanced safety features. 
We are supporting Fraser Crossing Partners, a joint venture between ACCIONA and Aecon Group Inc., by contributing our D.B. Patrick, staff and craft employees to this significant infrastructure development.

1936 Henry Hudson Bridge over Spuyten Duyvil Creek in New York, NY

(Archived Bridge Hunter; no Historic Bridges; 3D Satellite)

This 1,926' (587m) long bridge has a main span of 800' (244m). [Bridge Hunter]
 
mta
When it opened in 1936, "it was the longest plate girder arch and fixed arch bridge in the world. Originally built with only one level, the bridge's design allowed for the construction of a second level if traffic demands increased. Within a year and a half the upper level was opened. The upper level carries northbound traffic; the lower one is for southbound traffic."

United States beauty posted two photos with the comment:
The Henry Hudson Bridge is a steel arch toll bridge in New York City that spans the Harlem River, connecting the neighborhoods of Spuyten Duyvil in the Bronx and Inwood in Manhattan. It carries the Henry Hudson Parkway (New York State Route 9A) and has both upper and lower levels, with the upper level accommodating northbound traffic and the lower level handling southbound vehicles. The bridge was completed in 1936 and was designed by David B. Steinman, featuring a central steel arch with a span of 840 feet, which was the longest of its kind when it opened.
Operated by the Metropolitan Transportation Authority (MTA), the bridge was originally built as part of Robert Moses’s extensive parkway system and was intended to enhance access to New York’s parks and suburbs. Today, it is an essential connector between Manhattan and the Bronx, with scenic views of the Hudson River and surrounding landscapes. The Henry Hudson Bridge has undergone various renovations over the decades, including updates to its tolling system, which now uses electronic tolling to facilitate traffic flow and reduce congestion. The bridge’s location and design make it a notable part of New York’s infrastructure, balancing functionality with aesthetic appeal.

Tom Leigh: Joseph Buchalter many US railroads used "east" and "west" as general operating directions. Found this chatty link:

Steven Goin: I didn't realize those units were used on passenger trains. For some reason, I thought they were only used on the approaches to stations.
Jonathan Dandridge: Steven Goin they were used between Grand Central and Croton Harmon where they were swapped out for Diesels. I remember seeing them at GCT in the late 60s. Shortly thereafter when PC took over they brought in ex NH FL-9s dual modes and retired the electrics.
Bernie Bierman: Jonathan Dandridge But not before they had New York Central diesel E units entered the Park Avenue tunnel (because of the "deferred maintenance" policy applied to both T-motors and P-motors), almost asphyxiating both long-distance and commuter passengers. This was clearly the nadir of the PC, which actually faced a revolution by the normally staid commuters. It was after the service was handed over to Conrail that the old NH FL9's started to show up on the Hudson and Harlem Divisions.

In the south approach, there used to be a lot of columns in the lower (southbound) roadway to support the upper (northbound) roadway.

$90m dollars was spent to remove those columns and redo the toll booths. [entech],

In 2025, MTA plans to finish a $20m project to replace the sidewalk with an 8' (2.4m) wide structure so that bikers can legally ride their bike across the bridge. (They are now supposed to walk them.)

1955 Hyde Park (Swinging) Foot Bridge over Kiskiminetas River at Leechburg, PA

The Pennsy had squeezed tracks in both sides of the river. And this bridge connected those two routes. But the bridge had already been converted to a footbridge before 1953. I looked at older topo maps to see when it became a footbridge, but none of them even showed this bridge.
(I should have read the reference, uncoveringpa, first: "The bridge was originally constructed in 1886 for the local railroad but was destroyed in May 1889 during the same flooding that caused the Johnstown Flood. The bridge was rebuilt but was eventually abandoned in 1904.")

The bridge has three towers because it reused three Pennsy piers.
uncoveringpa
"The bridge is built on piers that were originally constructed in 1886 for a railroad bridge."
"This bridge is 600 feet [183m] long and sits about 20 feet [6m] above the river, making it a very impressive bridge and almost certainly the longest swinging bridge in PA....The first Hyde Park Walking Bridge was constructed of wood in 1920. At some point, likely due to wood’s deterioration, a metal suspension bridge was constructed in the same spot in 1955."

The first photo must be of the north end because the bridge is curved and the separate truss in the foreground is going over railroad tracks. The second bridge must be of the south end.

"The current Glenwood Bridge, which opened in 1966, is Pennsylvania's first all-welded, steel truss bridge."
 
"This bridge is unusual because most of the trusses are below deck except at the piers where they rise up forming a through truss design." [HistoricBridges]

It appears to be a former-B&O tower because the upstream railroad bridge is a former-B&O bridge.
