All roads are clear leading to Hartsfield-Jackson International Airport after some lanes were closed while fire crews investigated a possible gas leak Tuesday.

According to the airport’s Twitter account, @Atlanta_Airport, only one lane to the South Terminal was open around 5:45 p.m. and people were advised to use the North Terminal to access the airport.

By 8:30 p.m., all lanes were reopened leading to the South Terminal and normal operations resumed.
