The toll rate signs for I-66 inside the Beltway have malfunctioned both yesterday and today, leaving them dark for most or part of the morning rush hour. Tolls were waived on Monday during the outage, and rightly so, IMO, because how could anyone know what the rate would be so as to make an informed decision whether to use the road? They'll probably waive them today, too, but since the outage was for a shorter time, presumably they won't be waived for the whole rush hour.
Today's instance marks at least the third time this has happened within just a few weeks. They're blaming it on a "network" problem. I wonder what's going on. The I-66 HO/T operation is VDOT's responsibility, not Transurban's, and we haven't seen this sort of problem (yet, anyway) on the Beltway or I-95.
