MoDOT has announced lane restrictions on 270 between 170 and the river bridge from 20:00 to 05:00 on weeknights, weather permitting.

If this isn’t enough, though there has been no official announcement the IDOT traffic info map is tipping this one off for next month:

Today the NWS gave us bad news and confirmed that the Mississippi River at Alton will go past the 29 foot threshold as early as Monday.  The bad news when the river hits that point is that the southbound lanes of 367 just south of the Clark Bridge start to flood and that usually renders the southbound direction of the Clark Bridge off limits.alton-apr30at1700

The projected crest is on Wednesday at or around the 33 foot mark.

Based on an recent MoDOT press conference held this evening, the NB lanes of 367 will be converted into two-way traffic and that will help with the heavier than normal traffic on this section of 270. However, this also means that there will be delays in both the AM and PM peak starting Monday afternoon and lasting likely through the end of the week. Either way, traffic on 270 will be heavier than normal for a few days, the canal bridge area is a known choke point, and plan on delays on both the Clark Bridge and the Chain of Rocks.

MoDOT has announced lane restrictions on 367 north of the Missouri River that will begin tomorrow, weather permitting.  There is no exact reason why the lane restrictions are being given but they are bold enough to start the southbound lane restriction during the 07:00 hour.

Poor timing snow event for 1/5

The NWS has predicted up to 4 inches of the white stuff for Thursday – and projected the stuff to fall in time for the morning peak:

Earlier this evening, MoDOT goes out and their #2 man in the district declares in a press conference to the local media there will be no pretreating of the roads prior to the event.

Instead they have urged the people to stay off the roads and likewise the Illinois State Police has issued a travel advisory for the I-64 and I-70 corridors:

With the lights on the river bridge out and the poor timing of the event, the admins decided to upgrade the risk factor to HIGH. The hilly 270 mainline up in North County is likely going to be terrible, and in the last winter event that hill east of 157 proved its ugly head like no other. Since the admins have honestly lost count of how many incidents that happened on that hilly mainline in recent years (it seems like it happens every season), anyone that has to go out in this stuff due to essential reasons needs to allow extra time and be prepared to be stuck. Temperatures in this event is expected to be in the teens and low 20s, which can make rock salt rather ineffective.

Just for good measure, the past snow events at poor times have yielded big problems so please lets not make a repeat of this mess:

OR this mess the last time MoDOT didn’t pretreat the roads, or for good measure the epic twitter feed:

Whatever happens tomorrow please allow a lot of extra time or just stay home. The evening peak will likely be just as dicey depending on when the snow exits.

Warning: There may be some strong words – the admins do not censor profanity.
As the admins have warned in the past, December is the time where the big incidents tend to occur. This incident happened on a clear night with dry roads.

The admins are counting our lucky stars that the kids were out of school this week on the Christmas vacation – otherwise this incident would had caused bigger traffic chaos. This one came the morning after one of the admins had a late night at the WWE event (and slept through the whole ordeal) and another admin was only able to post right before work and during a break.

Below the admins will simply let the social media feed do the talking:


We will go to see how he handled that emergency detour routes in a minute.


This next video was not shown on the air but it was some behind the scenes. Police were forcing westbound traffic off at Route 3.



The admins did not do a lot of tweeting during the incident, but the feed was loaded.

This incident knocked out the lighting system on the bridge, and the lights are still in the dark as the admins write this post.

5 hours bro

MoDOT was blocking EB 270 mainline traffic at 367 and blocked ramps to EB 270 from Bellefontaine, Lilac, and Riverview.
If you haven’t figured out by now, about two years ago before the canal bridge implosion the admins came up with the page regarding emergency detour routes. Since 143 leading up to the Clark Bridge was likely going to be awful because of this incident (construction in downtown Alton was going on had parts of Ridge Street blocked for the past few weeks), one of the only traffic reporters that was not on vacation this week spent the entire traffic segment bragging about the southern detour routes.  (Couple that we knew that went northern routes got around Alton on 140 and Homer Adams Parkway.)  It is clear that the page was working as intended and nobody was bitching about traffic in the Riverbend on social media.

The incident was the main attention of all three major tv stations, several newspapers, and a few radio stations (had to be a otherwise slow news morning for this incident to get that much attention):

This incident shut down 270 for 5 hours, long enough to ruin an entire morning peak.  It only took one mistake to cause this chaos, and luckily came when the schools were closed for Christmas vacation, people were blowing their remaining vacation time for the year (traffic was lighter than normal all week long), and the weather was quiet.  Had this one happened a week later this chaos could easily rivaled the one that happened 6 years ago. There was an secondary incident during this chaos, a minor one that happened on EB 270 on the bridge that was quickly cleared.

WB 270 was backed up to 111 when it was all said and done. EB 270 was backed up past Lilac and that was because MoDOT was deploying crowd control at 367.


The lights are now out so please use caution, especially if the river fog risk goes to medium or high. Right now the winds are strong enough to keep that threat low but this weekend will not bring favorable weather and next week is too far out to consider the threat.


From 16:00 to 19:00 on Thursday, December 15, MoDOT will conduct a public meeting at McCluer High School at 1896 S. New Florissant Road.  Attendees will have an opportunity to tell it “as it is” for 2 minutes OR provide a written comment.  For citizens unable to attend there will be a time window where comments may be provided online with a deadline of January 6, 2017.  A preferred alternative has been determined.

This is the last chance of making MoDOT hear the heat so make it count.  The admins are obviously unhappy at the recent release of the draft maps so far as it appears little improvements will be done at Lilac and Riverview interchanges and no mainline lanes added (seems like an exit only lane from Lilac to Riverview).  In addition it seems like it will not happen before IDOT gets around in finishing their own study.

NOTE: some of the incidents that will be mentioned actually happened LAST WEEK but with two of the admins being out of the area for most of that week the focus was on Ride of the Century related stuff. 

First here is the video relating to the Ride of the Century that has pissed off the admins so much that it is worth posting it again:

Warning: video contains a lot of profanities.  Please watch with caution.  If you been wondering why Ride of the Century related stuff have to be posted every year, this video is a good reason why.  It is not about giving those crazies the attention: its about warning the truckers that are not familiar with this section of 270 about the stupidity that comes with this event.  One of the incidents that happened on 270 further into North County narrowly missed a tractor-trailer.

Ever since last week started, the evening peak has been anything but smooth sailing.  Last Monday one of the admins stumbled upon this incident on the way home from a work-related function:

It caused the eastbound lanes to back up to 367 and takes nearly 45 minutes to clear. It was just the beginning of a long night despite the fact one of the admins had a very early bedtime due to work:

While this incident did not impact the mainline, it caused ramp closures at Riverview and it was not until midnight before it cleared.

Two days later another eastbound peak hour incident took part near the canal bridge, and around the same time an westbound incident allegedly happened:

The traffic delays went back to 367 on the incident near the canal bridge, and it appeared that the live feed camera at Lilac was suggesting an alleged secondary incident that went unconfirmed.

If the new week was to be an improvement, it wasn’t:

The admins missed this one due to work related reasons but this one was westbound.

Today’s livechat on STLToday brought yet another question regarding the ramp from 270 to Riverview.  That ramp from Riverview to EB 270 is very dangerous and one of the admins knows that ramp very well.  Our pro tip is to come to a stop at the very top of the hill (but still on land, do not stop on the bridge) and wait for an opening and get on the mainline as quickly as possible.  Any countermeasure for this ramp is years away and probably will not occur before IDOT doing something about the river bridge.  However, developers have upped the ante in recent months, MoDOT resumed their North County study, and IDOT started their own study earlier this year.

Regarding the recent trend of crunch time starting as early as 06:30 up in North County, one of the admins have confirmed that.  The reason why it slows down at 367 is that the ramps between Old Halls Ferry and West Florissant is poorly designed and any incident at that time of the morning can back up traffic to the canal bridge.  270 up in North County is also hilly, so sight lines do have a role in the problems.  367 is also when all the Clark Bridge regulars get on 270.  There are Facebook groups out there that check traffic status on 367 and 270, so please make use of those groups.

This afternoon, this was posted on MoDOT page.  Since just about everyone has been waiting a very long time to tell IDOT as it is (MoDOT heard plenty during those I-270 North County public hearings), the information is posted below:i-270flyerfinal_000
Additional information can be found here.

 Note: unfavorable weather conditions for Monday and Tuesday has pushed the lane closures back til later this week.  Stay tuned.

If that project in North County last summer was bad enough, MoDOT is about to start a four month long construction project on 270 at Bellefontaine Road that is expected to screw both the morning and evening peaks for people that must use 270 to get between North County and Granite City.  With one mainline lane in each direction expected to be closed on a 24/7 basis, there is a lot of nerves going around.

This evening, for the second time in less than 3 weeks, a serious accident happened on eastbound 270 between Old Halls Ferry and 367 during the peak period that closed the highway for some time.  The incident this afternoon sadly proved fatal for one person and caused major traffic hell in North County.  In fact the westbound lanes were blocked as well for a short time during this incident.  A second incident on a route that people were using to get to Parker Road did not help matters either.

This incident lasted through the entire evening peak period.  Although a fatality often requires all lanes to be closed for a few hours for reconstruction – the fact it was the peak period in the peak direction, and the fact the only other east-west alternate routes in North County are Parker Road and Chambers Road – crews ended up reopening the right lane and allowed the traffic to sneak through the scene after an hour.  It takes over 3 hours to clear this incident.

With a recent rash of serious incidents near 367, the concern is there.  Most of the North County traffic on 270 enters and exit at 367 and the majority of that traffic is from the RiverBend.  The AADT (based in 2013) has traffic counts on 270 at 106K just west of 367 but 54K at Lilac.  While it is too soon to determine whether this lane closure will back up the peak traffic past 367 during the evening peak and east of Lilac during the morning peak, the risk of big problems developing is high.

Tonight from 21:00 to 05:00 tomorrow, there will be one lane closed in both directions on 270 from the river bridge to Route 3 so crews from Walsh Construction can install rumble strips along the shoulders.

Later this summer, eastbound drivers will be in for some major changes up in North County, so it is time to give some spoilers that have already been leaked to North County officials.  These changes will affect drivers that use either the Clark Bridge or this section of 270 to do their commute, so the people from the River Bend region that cuts through North County west of 367 needs to read this section below:

The first one will involved narrowed lanes and mainline being reduced to 2 lanes.

The second one is much more drastic – the eastbound mainline will be shut down at New Halls Ferry and traffic routed along the exit ramp and outer road system before traffic reenters past Old Halls Ferry.

The bottom line is that the evening peak will be hell once the work starts, as over 120K vehicles use that section of 270 from 170 to 367.  Start planning those alternate routes involving Parker Road and Lindbergh, especially if you opt for the Clark Bridge.
