The delay of the final long portion of the Sprain Brook from the Cross Westchester Expressway and the Taconic State Parkway near Hawthorne Circle spent multiple years without progress until demands were placed upon Governor Hugh Carey to get state funds attached to the project. The project had been delayed multiple times and local lobbying interests including Union Carbide threatened to back out of opening corporate locations in the area of the new extension, which in 1976 was slated to cost $20 million (1976 USD). The East Hudson Parkway Authority (EHPA) originally proposed raising the tolls on the Saw Mill River and Hutchinson River parkways and building new tolls on the Hutchinson, along with the Bronx River and Taconic parkways. However, NYSDOT reported during a meeting in Albany that contracts on the new extension would be given in 1978. However, the EHPA also wanted more monetary funds for the maintenance of the parkway system in Westchester and wanted to raise the tolls to help pay for that cost.
