Two redesigned ramps will open Wednesday at the interchange of the Northern State Parkway and Route 231 in Dix Hills.
The state Department of Transportation said drivers will have access to the new ramps from southbound Route 231 to eastbound Northern State Parkway and from eastbound Northern State Parkway to Route 231. The existing routes will be permanently closed upon the opening of the new ramps.
Traffic from southbound Route 231 will now enter eastbound Northern State Parkway via a new ramp just south of the overpass, eliminating a left turn entrance by way of Deforest Road. Signage will be in place to alert southbound travelers to stay right to enter on the new ramp.
Vehicles from eastbound Northern State Parkway to southbound Route 231 will now have a new, safer exit with a longer deceleration lane on the parkway.
Simultaneously, the exit 42N ramp from eastbound Northern State Parkway to northbound Route 231 will close to complete construction of a new exit ramp. Eastbound Northern State Parkway motorists wishing to head north on Route 231 will temporarily exit at the new Exit 42S ramp and make a left turn at the reconfigured traffic signal.
For real-time travel information, motorists should call 511 or visit www.511NY.org or the mobile site at m.511ny.org, New York State’s official traffic and travel information source. As with most road projects, work may be cancelled, postponed or prolonged due to inclement weather.
