Transmission Line Roadway Through Wetlands: Restored Critical Power Lost From Hurricane Michael
April 1, 2021
Learn how power grid network damage from Hurricane Michael was fixed in the wet, muddy Wetlands in Florida.
Project Background:
Hurricane Michael caused extensive damage to Florida’s power grid network, leveling more than 100 transmission towers in a 34-mile right-of-way from Port St. Joe to Callaway. This right-of-way crosses swampy, remote, and hard-to-reach areas, making rebuilding the grid even more challenging.
This extremely wet, muddy ground prevented repair vehicles from accessing the area for repair efforts. In order to install new towers in the shortest timeframe, helicopters were employed to bring in new steel towers.
Project Highlights:
• GEOWEB® 3D Geocells were used to stabilize roadways to support heavy vehicles in the wettest areas. • The GEOWEB Soil Stabilization System kept aggregate fill contained for a stable driving surface. • The fast-to-deploy and easy-to-install system helped an energy company rebuild the grid in three weeks, restoring over 75,000 outages.
