A Cobb County interstate ramp has reopened after being shut down for more than an hour during Monday’s morning commute while authorities investigated a suspicious package.

Georgia State Patrol troopers blocked the ramp from Canton Highway to I-75 southbound before 8 a.m. Monday. The Cobb County Police bomb squad was also on the scene.

The all-clear was sounded and the ramp reopened at 9:05 a.m., according to the State Patrol.

Authorities have not said what was in the package.
