I drove to Anchorage and back today and did notice the de-icing system had sprayed on the South bound side, but not on the north bound side. Both were well sanded by the time I came back. Wondering if the system took a dump on them again. When they first put it online it used way too much fluid and ran a seasons worth out in about a month. The contractor had to come back and redo the calibrations on the system. The cost of the fluid is quite high, if I remember right. Working or not, one needs to approach those bridges on the defensive. Slow down before you go on, and be easy on the throttle and the brakes until you are well past the bridge. That is common sense, as bridges do ice up easily.
