 However, planning for the proposed parkway system stalled and the plan was eventually abandoned.In 1937, plans for the highway were revived as the "Delaware Skyway", a planned elevated highway along the waterfront similar in design to the West Side Highway in New York, though these plans were also scrapped due to concerns that the supports would hinder access to port operations on the waterfront.In 1945, the city approved the current routing as the Delaware Expressway, envisioned to link all the industrial areas along the river with the Industrial Highway and the Trenton–Morrisville Toll Bridge to New Jersey.
