The Late, Late, Late Rush Hour?

You know, I understand that the eastbound on-ramps to I-66 may require ramp metering during rush hour ("One Car Per Green") to ensure that the number of cars entering is roughly equal to the number of cars exiting on the other end.

But at 12:30am? That seems unlikely.

This occurred as I was coming home from Arlington last week. And it wasn't the first time, either.

I'm no highway engineer, but I don't see the purpose, unless it's to make sure that the drunks are evenly distributed.
