All southbound lanes were shut down for more than three hours at Boggs Road while authorities were on scene. Even after the lanes reopened at 7:40 a.m., major delays remained from Buford to Lawrenceville, according to the WSB 24-hour Traffic Center.

Gwinnett County police towed a gold SUV and a yellow car from the scene of a deadly pedestrian crash before reopening the southbound lanes of I-85 at Boggs Road. The crash investigation shut down the interstate for more than three hours Thursday morning.

Authorities first closed the interstate north of the Ga. 316 interchange just before 5 a.m., the Traffic Center reported.

During the shutdown, southbound traffic was being diverted off the Pleasant Hill Road exit onto the access road.

At the height of the delays, there were seven miles of bumper-to-bumper backups, and I-85 was a parking lot. Commutes all across the Eastside were impacted as motorists crowded onto surface streets, WSB traffic reporter Mark Arum said.

The southbound lanes of I-85 were blocked at Boggs Road.

The investigation also impacted Gwinnett County Transit passengers. All express routes were delayed as a result, the agency said in a tweet.

Police have not released the name of the pedestrian or any other details about the crash.
