Signal 2131A: East Deer Park Road at Regency Lane

Signal 2131A is the traffic signal operating at the four way intersection of East Deer Park Road, Regency Lane, and Gables Court owned by Suffolk County and operated by the Town of Huntington. It is a span wire traffic utilized both incandescent and LED heads.

History
2131A's contruction year is unknown, however is was one of two signals built on East Deer Park Road (County Route 66) to allow safe exits from side streets on to the road since County Road 66 is a through road those wishing to travel between Jericho Turnpike and the Northern State Parkway. The second signal part of this plan is 2132A to the north. Unlike 2132A, it is assumed 2131A is still using most of its original equipment due to 2132A's heads and equipment looking newer.

Since it's inception, there have been multiple issues with 2131A and modifications. 2131A was known for spontaneously going into flash and correcting itself after a few seconds, this was due to a conflict monitor problem in the cabinet. However, this problem no longer persists, in 2019 as part of Suffolk County's Closed Loop Phase 9 Plan, 2131A received a new Caltrans Cabinet, effectively updating all controller equipment and fixing the flash problem. One other improvement made to the signal was the implication of newer pushbuttons for pedestrians to cross, as well as new ramps, however no PEDs exist at the signal. One other change made to the signal in 2018 was the replacement of the middle 3-way head, due to a broken elbow, this head was replaced with a newer all 12-way LED head.
