the parkway becomes the Saw Mill River Parkway as it enters Westchester County. History The Parkway was completed on October 12, 1937, under New York master builder Robert Moses. It cost $109 million, twice as expensive as the $49 million Hoover Dam that was built in the same period. The Parkway was part of Moses's "West Side Improvement" and included covering the New York Central Railroad's West Side Line, creating the Freedom Tunnel. The covered portion is partially used for the highway and also expands the Riverside Park designed by Frederick Law Olmsted. On July 23, 1991, construction workers found a dead child in a fridge just off the Henry Hudson Parkway. More than twenty years later, in 2013, a 52-year-old Eduardo Juarez confessed to assaulting and killing the young girl, who was his cousin. On May 12, 2005, part of a retaining wall at Castle Village collapsed onto the northbound lanes of the parkway, just north of the George Washington Bridge, shutting it down shortly before rush hour. The clean-up began quickly, and the road re-opened on May 15. Future The Henry Hudson Parkway is a candidate for designation as a New York State Scenic Byway, the first in New York City. At the request of the Henry Hudson Parkway Task Force, in 2005 the New York Metropolitan Transportation Council approved funding to develop a comprehensive corridor management plan, a requirement for its designation.
