Hurricane video showing stoplights not only swinging and blowing in the wind, but dangling and falling from the hurricane’s force, may be an item of the past.

In Baton Rouge, the Mast Arm is replacing the “stringed” street light. As noted in a previous column, the Mast Arm is a system of steel posts and arms, anchored in concrete, 12 feet deep, built to withstand Category 5 hurricanes.

Miami installed the Mast Arm in the 1980s; more were installed when eight hurricanes hit Florida in 2004 and 2005. It encloses wiring and the stoplights into one unit, eliminating the span wire traffic signal. Florida law requires them at all intersections within 10 miles of the coast.

Since its inception, none of the Mast Arms have required replacement.
