Signal 2037A: Deer Park Road at East Deer Park Road

Signal 2037A is the traffic signal controlling traffic at the intersections of Deer Park Road and East Deer Park Road, as well as East Deer Park Road and Deforest Road North. The signal controls 7 directions of traffic, Deforest Road North serves as part of the exit ramp for Exit 42N of the Northern State Parkway going westbound. Suffolk County controls updates to the signal with the town maintaining it.

Design
2037A is one of the most unique signals in Huntington due to the heavy volume the signal receives at the intersections it controls. The only direction where traffic must pass through both signalized intersections is southbound on East Deer Park Road (CR66). Northbound traffic to East Deer Park Road bypasses the first intersection with single section green arrows allowing the movement, however cars may have to stop at the second intersection at Deforest Road North.

Northbound traffic to Deer Park Road (CR35) is controlled by 2 unusual four section left turn signal heads. The heads have an additional solid red light on top meant for when the signal goes to flash. This, along with the single green arrow sections are the only ones the Town of Huntington has in their jurisdiction. The signal is also fully LED, with the old incandescent bulbs replaced in early 2018. Although the signal is very close to Dix Hills Fire Department's Headquarters, there is no fire department premption at his signal, instead, the Fire Department has its own remote traffic signal, 2001D, which 2037A is interconnected to. However, due to the Fire Department building a new facility located closer to 2037A with a new driveway, there is a strong possibility the signal will have to be reconfigurated.

2037A is the last signal in Huntington to utilize an auxiliary cabinet to house loop detector packs, the main cabinet is an old NEMA style using a Gammatronix control unit that is in interconnect with Signal 2131A located north on East Deer Park Road. These cabinets are scheduled to be replaced with a new Caltrans cabinet, apart of a closed loop project to modernize the technology on East Deer Park Road.
