Georgia's Elevated Highway Signs (how much, architect, traffic)

[architect77]

Over time, metal fatigue, vibrations, and poor workmanship have resulted in about a dozen of these cantilievered structures to fall over in the past decade (across the country, only 1 in Georgia).


Rather than beefing up the members of the structural posts, Georgia issued a directive that only a "balanced butterfly" post be used to elevate advanced guide signs.

On arguably the nation's widest highways, with 6 travel lanes in each direction depending on the sign's info to navigate though the lanes, do you Georgia's elevated "Overheads" are appropriate? I don't...

North Carolina is using sturdier structural posts:

I think I'd rather see the post-mounted sign than the cantilevered, regardless of how much reinforcing they put on the cantilever. At least if the sign falls, it's not falling on the traffic lanes.
