River fog and freezing temperatures turn the Thursday morning peak into a horror show

In the wee hours of Monday morning when the admins posted the fog risk threat for this week, there was more than enough factors in play to put Thursday morning at HIGH risk:  calm winds, a warm day, cool night, and most importantly temperatures expected to be near the freezing point.  After one of the admins got off work early Thursday morning around 02:00 – the fears were confirmed and by 04:30 the live feed cameras were only confirming what could been happening:

As the morning lows dipped to 28 in Alton the admins made at least two posts on Facebook warning that river fog was present with the freezing temperatures and extreme caution was to be taken.  If that was not enough, Laura Hettiger was running her mouth at least two times during the 05:00 hour on Channel 4 to be aware of the fog threat.  One of the admins went to bed before 06:00 and the other was on the way to work after 05:30 there was not a lot of monitoring on either the Facebook or Twitter accounts.

At or around 06:50, the first of the multiple incidents that happened in a 20 to 25 minute time window happened westbound west of 367 and a second happened eastbound between Lilac and Riverview:

Within 10 minutes this was being reported:

By the way, even around 06:45 there was still river fog in the area of the river bridge by a TV reporter that was making a trip across while en route to an unrelated story:

It was clear that the freezing river fog caused a few slick spots during the AM crunch time and as soon one happened, all shit broke loose.

The river bridge one was in a bad spot too causing crews from Mitchell Fire Department to walk to the scene to get to the people. Luckily only minor injuries were reported in this ordeal.

There were some live videos as well

In the end, the westbound lanes at the bridge were closed for over an hour and it takes at least 90 minutes before things return to normal. The average delay was at least 60 to 90 minutes.  This morning should reinforce why river fog under certain circumstances can lead to the big incidents and all three incidents were consistent with people allegedly driving too fast for the conditions.  In fact, we are approaching the 40th anniversary of one of the first epic fails that happened on this section of 270 and it happened on a morning with freezing temperatures and conditions favorable for river fog.  What happened this morning was minor compared to what happened on the morning of November 12, 1977, and back in the late 1970s there was not much of a morning news scene, no internet, no social media, and everyone relied on the evening newspaper to get their gossip and CB radio for traffic conditions.
