The old bridge was where the Beardstown River Look is now. The bridge was built for wagons and was never meant to be used for vehicles. Looked scary!

Because of the flood wall, they are now prepared for the river to get a lot higher.

1955 Bridge

John Weeks
"Beardstown was one of the earlier cities to be settled in Illinois. It was bigger than Chicago for several decades. The city was nicknamed Porkopolis due to the large pig yards and slaughterhouse operations. That trade shifted to Chicago when the railroad arrived in 1859. Beardstown was also a major hub of riverboat traffic, but that also diminished when passenger service was offered by the railroads."

John Weeks
"The Beardstown Bridge is one massive bridge, something that would only be expected on the lower Mississippi or other similarly large river. The main bridge is a through truss span about 1,365 feet long, with a 540 foot main span for navigation traffic. It rises nearly 70 feet above the water to the low steel line. To the north, there is a second through truss bridge about 710 feet long. A 1,000 foot long trestle crosses a backwater slough to the north, and a 500 foot steel deck truss bridge spans a creek on the south end. The overall river crossing is 2/3 of a mile."

HistoricBridges
"This bridge consists of a two span continuous truss and a three span continuous truss, making it a unique pair of truss styles."

Because of trees and the flood wall, this is the best street view that I could find.

1956 IL-141+IN-62 Wabash Memorial Toll Bridge over Wabash River west of Mt. Vernon, IN

(Archived Bridge Hunter; Bridge Hunter; Historic Bridges; Satellite)

Indiana built the bridge and charged tolls until July 1, 2014. [ArchivedBridgeHunter comments and indot]

The 2,400' (731.5m) long bridge has a main span of 427' (130.1m). [HistoricBridges]

It is so nice to see a steel bridge with a fresh coat of paint.

HistoricBridges explains that the design is a tied arch with a continuous truss.

This is where the arch part of the truss launches from a pier.

Another view of the arch part.

The Illinois approach is long because of a flood plain.

But the Indiana approach is even longer.

This is a view of the entire bridge. I dropped a pin to mark the west end. I could still see the east end after zooming out far enough to include the whole bridge because of the shadow on a field

1957,1992+202? I-476 Hawk Falls Bridges over Mud Run in Carbon County, PA

"The Hawk Falls Bridge Replacement Project is progressing, with construction estimated to commence in 2021. The replacement Hawk Falls Bridge will be a 720’ [219m] long steel structure featuring a 480’ [146m] deck arch span flanked by four 60’ [18.3m] deck plate girder spans. As with the current bridge, the new bridge will carry two traffic lanes in each direction, but it will also provide 12’ wide outside shoulders and 6’ wide median shoulders. Three welded, steel box arch ribs will be utilized to create an aesthetically pleasing structure that spans the deep Mud Run Valley located within Hickory Run State Park"

modjeski_replacement
"Nearly 3,500 tons of structural steel were used, with most external components made of uncoated weathering steel. This material blends with the site’s natural color palette and offers a durable, low-maintenance solution. Vierendeel struts between the arches, and the absence of spandrel column bracing creates a more open, graceful appearance, ensuring the bridge harmonizes with its surroundings."

pahistoricpreservation, courtesy of the Pennsylvania Turnpike Commission
"The bridge consists of a 738-foot [225m], three-span, continuous deck truss, with a single-span I-beam approach at each end. It was one of the tallest bridges on the Pennsylvania Turnpike system, with its road surface approximately 195 feet [59.4m] above Mud Run."
The replacement was supposed to be done by 2025. I'm writing this in Apr 2026 and it is not done.

1923+1957 US-90 Bridges over Pecos River west of Comstock, TX

The Pecos River is still skinny because the Lake Amistad Dam was not built until 1969.

The "new" U.S. 90 bridge over the Pecos River canyon under construction in this photo circa 1956. Located about 40 miles west of Del Rio, Tx. Previous river level road crossings had all been washed away in flash floods. Note the workers atop the concrete pier.

The bridge in the valley in the above photo must have been a construction bridge. The original US-90 bridge was further downstream at what is now a boat ramp. The road down to the boat ramp was the old US-90.

This is a mix of two topo maps. The black line is the old US-90 and the red line is today's US-90.

This shows how the road had to climb along the side of the canyon.
