- From the early 19th century on many plans had been proposed for building a bridge at this site, but it was not until the early 20th century that plans for a bridge began to be carried out. Many commissions and committees in both Pensylvania and New Jersey were formed and in 1918 the consulting engineers Waddell and Son were hired to examine the possibility of a Delware River crossing. In 1919 the states of Philadelphia and New Jersey worked together to create the Delaware River Bridge Joint Commission and they were given permission to build. The chief engineer for the bridge was Ralph Modjeski with Clement E. Chase as assistant engineer, Leon S. Moisseiff as the engineer of design, and Paul P. Cret as the architect. By 1921 a site for the bridge was chosen and construction began in January of 1922. The bridge opened on July 1, 1926 and is today known as the Benjamin Franklin Bridge.

- Designing Engineer: Hugh E. Young Consulting Engineer: Lewis M. Gram; The former bridge at Jefferson Avenue was a narrow swing bridge that needed to be replaced by around 1910. However, construction did not begin on the new bridge until 1920 and a detour for Jefferson Avenue was needed. The detour was created up stream with an old truss bridge from the Michigan Central Railroad, and was floated into place. Construction then began on a single trunnion, double-leaf bascule bridge that opened in 1922.
