Weather permitting, off peak daytime lane restrictions will happen on the river bridge from June 5 through June 8.

For Monday and Tuesday, one westbound lane will close from 09:00 to 15:00. Expect delays to begin near the Route 3 exit.

For Wednesday and Thursday, one eastbound lane will close from 08:00 to 15:00. Expect delays to begin near the Lilac exit.

Expect reduced speed limits on this section of 270 – and expect them to be enforced. Speaking of speed limits, we know this section is enforced on a regular basis as is:


This week is also the week where the DOT is conducting their annual safety check so truckers must take extra precautions and additional delays east of Route 3 may be encountered.

The NWS has set this area to Moderate Risk for severe weather as the main event is expected to roll through this area late this afternoon.  While this section of 270 is on the fringes of the Moderate Risk threat, the main threat of this outbreak being strong winds is a concern for the truckers that are using this road during the holiday weekend.

The admins think the worst will happen to the south and especially the southwest of here.  There is a preceding line forming that could affect the potency of the severe storms later this afternoon.

While a tornado watch is now out, it does not include this section of 270 at the time:

However, a severe storm watch was issued as the admins were writing this post:

Please stay weather aware this afternoon.

Lane closures like this one will be in effect for WB 270 both Wednesday and Thursday

Weather permitting, IDOT crews will close the right lane on WB 270 at the river bridge between 09:00 to 12:00 Wednesday and 09:00 to 15:00 Thursday to make repairs to the bridge deck.

While crews are out expect reduced speed limits and delays if your trip goes through this section of 270.


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.

Weather permitting, there will be lane restrictions on EB/WB 270 between 255 and 157 on Sunday for the purpose of utility crews to finish a power pole replacement.  There could be full mainline blockages up to 15 minutes at random times during the day.  From 07:00 to 20:00 two lanes in each direction will be blocked, so plan on using 162 or New Poag Road to get around.

If you decide to go through 270, don’t be this guy getting busted allegedly doing 91 just to the east of Route 3:

OR the one that did at least 110:

The bottom line: expect reduced speed limits and expect them to be enforced.

Really need to discuss a possible severe weather threat but since the SPC is putting this section of 270 on the fringes of the threat yet again the admins have decided instead to mouth off at a recent problem:

That incident during the evening peak last week caused at least two tire blowouts, one just to the east of Lilac and the second closer to the Riverview exit. Traffic was backed up to 367 and this was not the only alleged tire blowout reported.

Yesterday one of the admins drove by at least three blowouts between Lilac and 111. One of the vehicles lost an entire front right tire and was partially blocking an exit ramp waiting for help. There is a good 10 mile section of 270 between New Halls Ferry and 255 that tire debris is common place and the mainline pavement is a piece of shit (complete with a massive pothole at or near the 28.8 MM on the Missouri side and another just to the east of Route 203 – both in the eastbound lanes).  The very worse of the pavement is between Route 3 and Troy with both mainline lanes resembling the “washboard” pavement (complete with the apparent last resurfacing project approximately 20 years ago) from the heavy tractor-trailer usage.  There is another alleged spot on the westbound lanes of the river bridge just before the Riverview exit that looks like any attempt of a patching job ultimately fails over a period of time.

This has caused a lot of tires blowing out with at least 10 incidents since last week.  While the rainy weather has contributed, the tire blowouts usually occur when the temperatures are pushing 100 degrees, not 60 degrees.  With warmer weather out there the crews will likely be putting up the orange cones somewhere in this area this year although no major work has been announced.

The incident from this morning doesn’t appear to be from a blowout but there are pieces of tire visible in the foreground.

 

While the NWS DOES NOT have Winter Weather Advisories in effect for this area (but they do have in effect in the counties along and north of I-72), snow is expected to come just before the Monday morning peak:

While the ground temperatures are above freezing, an recent cold snap and the fact nobody has seen the white stuff for two months may mean very slick roads. (There has been more severe weather outbreaks than inches of snow this season to put this in perspective.) With that in mind combined with a recent run of terrible form when it comes to the North County drive (with last week AM peak fatal MVA on WB 270 in consideration), the admins made the decision to put the AM peak at HIGH risk. (It is also a full moon out there as well so people may be driving much more crazier than normal.)

While not a lot of snow is expected (the worst is expected to remain to the north), the timing can cause big problems as it does not take a lot of snow to cause gridlock, given that 270 up in North County is hilly and the 1-3 inch range is where people often get complacent when it comes to snow.

Although some of the previous models have put this section of 270 on the fringes of the severe weather threat, some of the latest model runs this morning is pointing to an enhanced threat.  While the TORCON is set at 4, the biggest risk is an outbreak consistent with an derecho:


This is the second possible severe weather outbreak in a week, and the first one the threat just missed to the east with the hail while the worst was about 75 miles south.

The risk forecast for Tuesday morning has been upgraded to medium as is may affect the morning peak. Stay weather aware as conditions may change in an instant.

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.
