Charleston County High Wind Bridge Procedures:

Hurricane Idalia is expected to have maximum sustained winds of 35 knots, with maximum gusts reaching 50 knots. The Charleston County government does not shut down bridges during tropical storms. While bridges won't be officially closed, Joint Base Charleston leadership urges base personnel to avoid driving on the bridges under the following high wind conditions:

Condition Yellow: 30 mph sustained winds

• Vehicles are advised not to drive on 65-ft or higher bridges or exposed bridges.
• Drivers should use extreme caution if they decide to travel over bridges.

Condition Red: 40 mph sustained winds

• Bridges 65-ft or higher and exposed bridges are unsafe for public travel.
• At these wind speeds, officers may not be present at bridges due to unsafe conditions. Drivers do so at their own risk.
