Suffolk County Road 39 is the major transportation challenge facing residents, businesses and visitors to the East End. SCDPW, and its local partner agencies, including towns, villages and New York State have utilized all their available resources to tackle the ever-growing traffic congestion of CR 39 and much of the surrounding roadway networks. The Corridor Study of County Road 39 seeks to develop, evaluate, and identify the long-term roadway and transportation system improvements aimed at reducing traffic congestion, minimizing local detours, and improving safety along County Road 39 and its surrounding corridors. This study will balance the needs of local communities, employment trends, zoning and future developments.

• The SCDPW project team is extremely familiar with existing conditions.
• This Planning Project is the first step to address traffic issues plaguing the CR 39 corridor.County Road 39/North Road is the critical artery to the South Fork.
• Only major highway/roadway east of Shinnecock Canal.
• SCDPW has used all traffic management tools available, yet congestion continues to grow and affect all residents, workers, and visitors to the South Fork.
• Businesses, schools, and hospitals  struggle to find employees willing to travel to the East End

Suffolk County Road 39 and the entire East End have seen consistent growth year after year. There is no more peak season for the corridor, as traffic volumes and congestion are present throughout the year. Everyday, as CR 39 reaches its capacity, vehicles divert to local streets to bypass the stop-and-go traffic conditions.

Since the 1960s, Suffolk County Road 39 has been studied and improved incrementally to both address the challenges of the day and to plan for the long-term.
