Senator Bill Roth, who saw the need for a new crossing, was a main proponent in securing federal funding for the new C&D Canal Bridge.

After construction of a new toll freeway that opened on January 10, 2019, US 301 uses neither bridge, and terminates at DE 1 just north of the Biddles Corner tollbooths.

Also during this time, the northbound free access to the bridge was moved 1 mile south to the intersection of US-13 and Port Penn Road at the Biddles Corner tollbooth.

The new ramp passes between the tollbooths and the plaza building (no tolls collected) and rises to merge briefly onto US-301 north just before its end at DE-1.

Lead paint exposure created a public health risk in 2000 during the sandblasting and repainting of St. George's Bridge over the C&D Canal.
