Two of three westbound lanes of Sunrise Highway/Route 27 will be closed in the Oakdale/Bohemia area between 6 a.m. and 10 a.m. Sunday while work to inspect overhead signs is conducted, according to the state Department of Transportation.

Spokeswoman Eileen Peters said the department tries to minimize impact on traffic and the 6 a.m. to 10 a.m. Sunday time frame was “the least interruptive four-hour period,” according to traffic safety division engineers. Overhead signs are inspected annually to check their structural integrity.

The westbound lanes will be closed between Oakdale-Bohemia Road and Connetquot Avenue, with a single lane left open to drivers at all times on the highway and entrance and exit ramps.

Emergency service providers and local officials have been notified of the lane closures, DOT officials said.

Drivers are being warned in advance of the closure via electronic signs, and department officials strongly urge motorists to use alternate routes or they will experience travel delays. Those who cannot use alternate routes are reminded to drive carefully through the work zone, follow the posted detour signs, and obey the flag person’s directions, for their safety as well as the safety of the highway work crew.

The work will be done weather permitting. Drivers can call 511 or visit www.511NY.org for 24/7 up-to-date traffic and travel information.
