The Hutchinson River Parkway (reference routes 908A and 907W) connects I-678 to the Merritt Parkway in Connecticutt. The first section opened in 1927 and the intial 11 miles, completed in 1928, ran from US 1 to Westchester Avenue. The parkway was then extended north to Connecticutt and south to Pelham Bay Park in 1937. The final extension to the Bronx-Whitestone Bridge was complted in 1941, part of which was later incorporated into the Whitestone Expressway with the designation of I-678. The exit numbers were formerly continued on CT 15, however became discontinuous during an adjustment to the numbering on the New York side. The exit numbering was adjusted again in 2021 to convert to mileage-based exit numbers. The toll booths north of US 1 were removed in 1994.
