Left: Looking east from the River Road overpass over I-215, in the southwestern suburbs of Salt Lake City.
In the mid-80's there was a calamitous multi-vehicle accident in the fog at this location, so it seemed like a good place to situate one of our liquid CO2 fog control devices (we placed Unit B nearby, at the Murray Parkway Golf Course Maintenance Shed).
At one point, I noticed that although there were all kinds of gas masks and warning signals at the ready in the event of a massive chlorine spill at the Sewage Treatment Plant, we visitors had been issued no gear, and no instructions. "If you hear those alarms go off," one plant worker stated, "you should run, run, run away just as far and as fast as you possibly can, and don't you dare open your mouth, or even think about breathing!" Whew! That put my mind at rest! They had given some thought about the visitors after all!
The absence of fog this particular winter of 1989/90 gave us little experience in the effectiveness of liquid CO2 seeding for improving visibility for traffic. It was a lot of work putting these things together, however, for little in the way of grant money. Kind of reminds me of community theater in that respect....
Since 1990, I know that there has been at least one major multi-vehicle accident in the fog near this location.
