MET Towers

MET Tower obstructions must be reported in accordance with House Bill 0546 and may also contain information about other obstructions that may be a hindrance to low-flying aircraft. To report obstructions or to view locations of obstructions click here. Additionally the Department of Transportation also maintains MET towers near roadways that wind developers may find useful as a screening tool.
