Update: All lanes open on I-77 after morning crash in York County SC backed up traffic

·3 min read

All southbound lanes of Interstate 77 near Exit 82 in York County, South Carolina, re-opened Friday afternoon after a multi-vehicle crash involving a tanker and other vehicles.

The four lanes of southbound I-77 close to the Catawba River were operating after 3 p.m. and the site had been cleared, said Chuck Haynes, York County Emergency Management Director.

The crash north of Rock Hill city limits blocked part of the highway for hours from the overnight hours through the morning commute. Then, two lanes re-opened shortly before noon, according to Haynes and the York County Sheriff’s Office.

Traffic had been backed up on I-77 southbound more than six miles to Exit 88, before two southbound lanes re-opened before noon, officials said.

The S.C. Highway Patrol is investigating the crash but has not released details about the collision.

The back up on the northern side of the crash site caused delays for Fort Mill school district transportation, said Joe Burke, spokesman for the school district.

The district sent out an alert to parents that said:

“We are experiencing bus delays with all routes this morning due to the increased traffic caused by the closure of I-77. We are working to get students transported as quickly as possible but there will be delays across the district this morning.”

Effects on Rock Hill school district traffic were limited mainly to staff who might live north of the district and had to deal with traffic getting to campuses, said Lindsay Machak, spokesperson for the Rock Hill school district.

The York County Sheriff’s Office sent out alerts through the morning hours about the crash.

“There are several people with injuries but no deaths at this time.”

Haynes said one of the vehicles involved was a tanker carrying gasoline. No gasoline spilled from the tanker, Haynes said.

There was no fire, Haynes said.

A small amount of diesel fuel from the truck did spill on the road, Haynes said.

The highway patrol, Riverview Fire Department and other emergency responders were on scene.

Only 2 ways across Catawba River

An alternative route for traffic was U.S. 21. That highway parallels the interstate from Rock Hill to Carowinds Boulevard near the North Carolina state line.

There are only two bridges in that area -- I-77 and U.S. 21 -- where traffic can move across the Catawba River. All traffic had to use the southbound U.S. 21 bridge, Haynes said.

The number of vehicles involved in the crash has not yet been revealed.

Photos shared on social media by the York County Sheriff’s Office show the tanker truck was left upside down near the Cherry Road exit into Rock Hill.

The South Carolina Department of Health and Environmental Control was notified, officials said.
