Opened 18 Feb 1952. Originally a toll bridge: cars, 10 cents; trucks, 25 cents. Toll booth was located on the Westmoreland County side. Tolls were removed in 1961 as the last state-maintained toll bridge.
Before the bridge was built, the nearest crossings were at Freeport (Garvers Ferry Bridge) and New Kensington (Ninth Street Bridge).
Originally named the Tarentum-Valley Heights Bridge. In the 1960s, the New Kensington-Tarentum Bridge. Officially renamed on 1 June 1973, George D. Stuart Bridge to honor the former editor of the Valley News Dispatch newspaper and three-term State House member. Rep. Stuart pushed for the $4.5 million to build the structure.
Ramps in Tarentum replaced the Ross St Viaduct, both in location and in function. The viaduct, closed in 1949, was built in 1903 to allow trolley and motor vehicle to cross the Pennsylvania Railroad between Third St and Sixth St.
The PRR tracks mark the route of the Pennsylvania Canal which crosses Lock St north of the Tarentum Bridge.
