I-81, I-690 Lane Closures Impact Syracuse Traffic During Viaduct Project

Multiple highway and ramp closures are scheduled in South Dakota and Syracuse, New York, to facilitate bridge and viaduct construction projects. In South Dakota, the westbound Interstate 90 on-ramp at Hartford (exit 387) will close temporarily on September 11 for a bridge deck pour, with traffic detoured to nearby exits; this $12.6 million project is expected to finish by June 2026. In Syracuse, lane reductions and ramp closures on Interstate 81 and Interstate 690 will occur from September 8 to September 20, including overnight and daytime restrictions to support the I-81 Viaduct Project. Drivers are urged to slow down and obey traffic controls in these work zones, where fines for speeding are doubled and repeated violations may lead to license suspension. Detours and alternate routes have been established to mitigate traffic disruptions during these construction activities. Weather conditions may affect the schedule and duration of these projects.
