Sep 3, 2014 21:29 Pat Shingleton’s Weather News for Sept. 4, 2014 Pat Shingleton’s Weather News for Sept. 4, 2014 Swinging signals and mast arms BY PAT SHINGLETON | WBRZ chief forecaster Sept. 03, 2014 Comments Video coverage of tropical storms, hurricanes and damaging thunderstorms include the swinging and swaying of traffic lights. Hurricane video also offers swinging stoplights, dangling and crashing from the hurricane’s force. Wire and cable connected street lights are a thing-of-the-past in Baton Rouge. In the 1980s, Miami was the first city to install “Mast Arms.” When eight hurricanes hit Florida in 2004 and 2005, Mast Arms remained intact. These devices enclose wiring and stoplights into one unit, eliminating the needed repair for span-wired traffic signals. Florida and other coastal states require Mast Arms at all intersections within ten miles of their respective coasts. Mast arms have more damage from car crashes than crashing storms.
