DEP to Begin $5 Million Upgrade of Intersections Near Kensico Dam in Westchester County

The New York City Department of Environmental Protection (DEP) announced that construction will begin this month on a $5 million project to improve the flow of traffic and pedestrian safety at eight intersections near Kensico Dam in Westchester County. The project is rooted in changes that happened after the terrorist attacks of 9/11, which required DEP to permanently end vehicular traffic on the roadway atop Kensico Dam. That roadway is now open only as a recreation path for walkers, joggers and cyclists.

A DEP study found that closing the roadway over the dam resulted in additional cars driving through the hamlet of Valhalla and its surrounding residential neighborhoods. To mitigate that effect, DEP has worked for years with local officials to plan a number of traffic-control improvements that would help cars and pedestrians travel more safely. The results of that planning effort is a $5 million project that will begin this month and last approximately two years. The project includes myriad upgrades to highways, traffic control devices, crosswalks and more. The following upgrades will happen at eight intersections near the dam.

Site 1: Route 120 (King Street) at Nannyhagen Road

  • A new traffic signal will be installed
  • A northbound Route 120 left-turn lane will be added
  • The southbound Route 120 lane will be realigned to accommodate the new turn lane
  • Drainage swales will be constructed

Site 2: Lakeview Avenue at the Taconic State Parkway

  • A westbound Lakeview left-turn lane will be added
  • The traffic signal will be upgraded
  • Roadway signs and striping will be upgraded

Site 3A: North Broadway Avenue at Route 22

  • A southbound through lane will be added to North Broadway Avenue
  • The traffic signal will be upgraded
  • The loop detector, which detects cars waiting for the light, and signal timing will be upgraded at Sir John’s Plaza
  • Roadway signs and striping will be upgraded

Site 3B: Hillandale Avenue

  • A sidewalk will be added to Hillandale Avenue
  • Pedestrian crosswalks and signs will be added along North Broadway at Hillandale Avenue
  • Pedestrian crosswalks and signal poles will be added at Hillandale Avenue and Route 22
  • The traffic signal timing will be modified to include pedestrian phases
  • Roadway signs and striping will be upgraded

Site 4: Legion Drive and Columbus Avenue

  • A new traffic signal will be added in front of the fire station, including controls inside the station that will allow firefighters to stop traffic and get their emergency vehicles out quickly and safely. Roadway signs and striping will be upgraded

Site 5: Park Drive and Broadway

  • A new traffic signal will be installed
  • A flashing “Signal Ahead” sign will be added
  • Roadway signs and pavement markers will be upgraded

Site 6: Taconic State Parkway at Cleveland Avenue

  • A flashing “Signal Ahead” sign will be added along the southbound Taconic State Parkway

Site 7: Westland Drive at Route 22

  • Old traffic signal poles and overhead wires will be removed

DEP will work on these intersections one at a time throughout the next two construction seasons. Those traveling through the area should expect to see flaggers, signs and intermittent lane closures that are meant to ensure the safety of construction workers. No road closures or detours are planned to accommodate the work.

DEP manages New York City’s water supply, providing more than 1 billion gallons of high-quality water each day to more than 9.6 million New Yorkers. This includes more than 70 upstate communities and institutions in Ulster, Orange, Putnam and Westchester counties who consume an average of 110 million total gallons of drinking water daily from New York City’s water supply system. This water comes from the Catskill, Delaware, and Croton watersheds that extend more than 125 miles from the City, and the system comprises 19 reservoirs, three controlled lakes, and numerous tunnels and aqueducts. DEP has nearly 6,000 employees, including almost 1,000 scientists, engineers, surveyors, watershed maintainers and other professionals in the watershed. In addition to its $70 million payroll and $168.9 million in annual taxes paid in upstate counties, DEP has invested more than $1.7 billion in watershed protection programs—including partnership organizations such as the Catskill Watershed Corporation and the Watershed Agricultural Council—that support sustainable farming practices, environmentally sensitive economic development, and local economic opportunity. In addition, DEP has a robust capital program with $19.7 billion in investments planned over the next decade that will create up to 3,000 construction-related jobs per year.
