A few followups from last week. MetroWest asked about the guard cable on Route 100 in Franklin County between Wolf Hollow and Elizabeth Ann. That should be repaired by the end of this week, weather permitting.
We were also asked about some tree cutting along I-44 in Webster Groves -- that is Ameren that is clearing up trees along the power lines.
Finally, we had a question about the positioning of guard cable. Guard cable’s key purpose is to help prevent crossover-type crashes. It needs to be placed in a certain position along the roadway in order help prevent a car that leaves the road from crossing over into on-coming lanes. Typically it is placed based on a number of factors, that includes the tensioning of the cable and the width of the area between the two directions of traffic. However, we can choose to alternate the guard cable to help reduce potential driver perception that there is an obstacle close to the lane in which they are traveling.

It looks like that was a repair on the deck that popped -- most likely due to the changing temperatures. Typically, that is caused by the expansion and contractor of the roadway and patch due to weather, coupled with the vibrations of traffic on the bridge, which shook the patch loose. We appreciate the kudos to our bridge maintenance team. Andrew Gates, MoDOT Communications
Thanks for the details -- I have asked the traffic engineer team to take a look at the area to see if they may be able to make any improvements. Andrew Gates, MoDOT Communications
Off hand I don't believe there are any improvements programmed for those routes aside from potential repaving associated with utility upgrades, aldermanic projects, or redevelopment efforts.
That is a drawback of keeping the roadway open while making repairs on bridges. While the concrete is setting, it can get rough from the vibrations of traffic continuing to drive over the bridge. We still have work on the bridge at I-55/I-44 (although the lanes with the new concrete are essentially complete). We are looking at some options to smooth out the concrete there.

We are scheduled to proceed with the improvements at Musick and Gravois this year. Once that work is completed (ideally, this calendar year), we'll move forward with the Musick bridge replacement. David Wrone, St. Louis County
Since adjustments were made as mentioned we haven't seen issues as described. We will record travel times to verify & respond accordingly.
We will check with the contractor & have them address this promptly.
