Gated Exits on I-64? Why?

Factual Questions
1

While visiting Colonial Williamsburg, I noticed most exit (and entrance) ramps off and onto I-64 are gated! While I wager the gated entrance may be used to regulate traffic flow during rush hour (perhaps into NNews/Norfolk?), who in the world would gate an exit? These gates are a few car-lengths off the highway. Can you imagine the mess that would cause?

Bonus: Even odder, the gates are doubled! There are TWO gates directly across from each other for each ramp where one gate is long enough to block the ramp. (And, how much did VA taxpayers get taken for to implement this over-designed system?)

*I hope this doesn’t double-post. I just submitted this when the Boards blinked and my original thread seems to have been lost in cyberspace.

Hurricane gates.

If you don’t know what they’re for, you’re not exactly in a position to call them “over designed”, now are you?

Ok, but why a double gate? They’re not even staggered from each other. If one fails, the other (of similar design) isn’t too far away, is it? Also, is the plan that I-64 can use all lanes to go away from the area?

After reading down on the link,
:o No futher questions. :smack:

It seems they must be slightly staggered, but driving past, it is hard to tell.
Good show, QED.

I must say that $3 million seems a little expensive for those 2 gate.

The $3 million is for all of them, not just the two in the picture.
