Project Goals and Objectives• Provide direct access to Crooked Hill Road from the LIE.

• Provide access from Crooked Hill Road to the LIE.

• Create better traffic flow between Crooked Hill Road and the LIE Service Roads.

• Enhance overall traffic operations usingtransportation improvements to reduce congestion and delay.

Project Needs• Increased vehicular movements in the vicinity of Crooked Hill Road (CR 13) and a lack of routing options to access businesses and services from the Long Island Expressway(LIE/I-495).

• Lack of direct access from the LIE to Crooked Hill Road has resulted in congestion at the LIE Service Roads and Commack Road, Crooked Hill Road, and Wicks Road intersections.

• Employ night work, when feasible.

• Institute Seasonal / Holiday limitations.

• Utilize lane width reductions and traffic shifts to keep travel lanes open.

• Minimize impacts by performing construction in stages.

• Limit lengths of work zones to minimize disruptions to motorists and the community.

• Maintain driveway access at all times.

• Utilize temporary work zone measures designed according to the "Manual on Uniform Traffic Control Devices” (MUTCD) and NYSDOT standards to maintain motorists’ safety.
