Suffolk County rushes Smith Point Bridge repairs before summer season

The Smith Point Bridge is down to one lane with alternating traffic, and if Suffolk County misses its Memorial Day target, the bottleneck could reach from Shirley to the beach gate just as summer crowds, local businesses and emergency crews need the crossing most. County officials said they hope to restore two-lane traffic by Memorial Day, but they have not guaranteed the work will be finished by then.

Crews were seen working beneath the bridge as emergency repairs moved ahead after an inspection last year found structural deterioration. The span, built in 1959, is the sole vehicular access to Smith Point County Park and the eastern end of Fire Island National Seashore, which makes every delay more than an inconvenience for beachgoers coming off William Floyd Parkway and for nearby businesses that rely on summer traffic.

Suffolk first moved to emergency truck restrictions in November 2025, cutting the bridge to a three-ton limit after the deterioration was found. The county later said it worked with the New York State Department of Transportation to keep one lane open at a 15-ton limit so emergency vehicles could still reach the beach while the bridge was being studied and retrofitted. That temporary setup now carries the full burden of peak-season access.

The bigger fix is still ahead. Suffolk says a new Smith Point Bridge will be built just west of the existing structure, with construction expected to begin in the coming weeks and completion targeted for 2029. The replacement is projected to cost more than $100 million and will be 1,812 feet long, with two travel lanes, shoulders, ADA-accessible pedestrian and bicycle access, and improved storm and flood resilience. The county says the new fixed-span bridge is designed for a 75-year service life.

Officials say the old bridge will remain open during construction to minimize traffic disruption, but the county is managing that plan while other coastal crossings also face pressure. In Hampton Bays, the Ponquogue Bridge project is meant to remove a five-ton load posting, and the Fire Island Inlet Bridge to Robert Moses State Park was also slated for repairs after a hole was found in the roadway. Inspection reports dating back to 2020 had documented rusted steel supports, cracking concrete and exposed rebar there.

For Suffolk, the Smith Point work is now a test of whether an aging coastal road network can be kept moving through the season without cutting off one of the county’s most heavily used summer gateways.
