Residents, businesses and visitors should be aware of the SCDOT I-77 Catawba River Bridge Project which will last from May 6, 2021 at 7 p.m. until May 24 at 5 a.m. Since there are limited routes over the Catawba River, this will have significant impact to both York and Lancaster County motorists. Those who frequently use I-77 between Charlotte, NC and Rock Hill, SC are strongly encouraged to allow extra time, consider alternate routes, explore telework options and adjust work hours, if possible, during the project.
Visit the York County Sheriff's Office I-77 info webpage for information related to the SCDOT project and local impacts. The Sheriff's Office will also post any real-time information about accidents in the project area.
SCDOT Bridge Project Press Release
The SCDOT project will close the southbound bridge, with southbound traffic diverted to the northbound lanes to accommodate two-way traffic over the bridge, two lanes in each direction. A temporary concrete median will be in place to separate the northbound and southbound traffic. The southbound on-ramp at Sutton Road (exit 83) will be closed, with all northbound on-ramps closed at Cherry and Celanese (exit 82). Local law enforcement agencies and Highway Patrol will be stationed at the closed ramps at all times throughout the project.
Heavy delays are expected on I-77 and on the posted detour of US 21 to Sutton Road, as well as other roads used to access I-77 and alternate routes, including Highway 49/Buster Boyd Bridge and US 521. Motorists should also expect delays on local roads, including SC 160 and Sutton Road in Fort Mill, and Celanese Road, Cherry Road, Cel-River Road, and Dave Lyle Blvd in Rock Hill. Avoid those roads if possible, especially during rush hour.
Neighborhoods near the impacted routes, such as Riverwalk, Baxter, and Kingsley should expect a significant increase in traffic and delays on nearby roads, as well as a possible increase in cut-through traffic. Use caution as drivers who may be unfamiliar with neighborhood streets try to navigate to their route.
Traffic flow is expected to be restored to regular patterns before Memorial Day weekend.
