Columbia–Wrightsville Bridge

[2] 100,000 cubic yards (76,000 m3) of concrete and 8 million pounds of steel reinforcing rods were used, and coffer dams were built to aid in construction.

Tolls of 25 cents per vehicle were charged when the bridge first opened (equivalent to $4.56 in 2023) and ended on January 31, 1943, when the bond issue was retired.

Two of the original bronze light fixtures can still be seen on the front lawn of the Frank Sahd Salvage Center along Route 462 in Columbia.

The discovery resulted in a weight restriction of 10 short tons (9.1 tonnes) being applied, except for emergency vehicles that need to cross.

Interim repairs are planned and, with an expected need for redesign, the already-scheduled bridge rehabilitation is being pushed back to 2025.

The bridge accommodated east–west traffic across the Susquehanna River for 14 years before being destroyed by ice, high water and severe weather on February 5, 1832.

The wood and stone structure had 27 piers, a carriageway, walkway, and two towpaths to guide canal traffic across the river.

[citation needed] The structure was modified in 1840 by the Canal Company at a cost of $40,000 (equal to $1,220,800 today) concurrent with the construction of the Wrightsville Dam.

Due to fear of fire caused by locomotives, rail cars were pulled across the bridge by teams of mules or horses.

To prevent the advance of Confederate troops across the river from the Wrightsville (York County) side during the Civil War, the bridge was burned by Union militia under Maj. Granville O. Haller and Col. Jacob G. Frick on June 28, 1863.

Early and John B. Gordon had originally planned to save the bridge despite orders from General Robert E. Lee to burn it, and Union forces under the command of Colonel Jacob G. Frick had burned the bridge, originally hoping to defend and save it.

A steel truss bridge made of 200-foot-long (61 m) prefabricated sections, it was designed to be resistant to fire, ice, water and wind, elements that had destroyed previous wooden structures.

Like the previous bridges, tolls were collected to recover a portion of the half-million dollar investment, equal to $18,312,000 today.

The iron and prefabricated steel structure had a railway to carry rail traffic for the York Branch of the Pennsylvania Railroad, and twin carriageways that were shared with pedestrians.

The "Iron Bridge" carried passenger trains until 1954 and freight traffic until March 13, 1958, and was dismantled for scrap starting in 1963 and ending in November 1964.

Its stone piers, dating to pre-Civil War times, still stand today, running parallel to the north side of the Veterans' Memorial Bridge.
