At this point, our plans are that Vandeveter to WB I-44 should remain open for the remainder of the year. We anticipate it closing when we work on the westbound bridges between Grand and Kingshighway next year. Andrew Gates, MoDOT Communications
Typically due to the cost of the pre-emptive equipment that they would have to purchase; and, they can run through the signal legally, when they are under lights and sirens. Andrew Gates, MoDOT Communications
There are several signs to tell individuals on the outer road to stop before turning. If they do not choose to do so, then that is something that law enforcement needs to address. There will be some changes coming up to the interchange that may change the traffic patterns over the next few months. Andrew Gates, MoDOT Communications
Our traffic signal staff will check this out - thanks for the heads up!
That southbound left turn movement is one of the coordinated phases (along with the southbound movement) due to the travel pattern/volumes at that location. As such, they are called up each time for a guaranteed amount of time as well as the extra "unused" time from the inactive movements. This works well during the normal hours of day where traffic is present & heavy. However possibly at night when activity is much less, we can consider running the signal not in coordination wherein it would react only to whatever vehicle demand is present. We are evaluating the use of the lanes on McCausland near Canterbury and Arsenal to see if a better lane utilization can be accommodated.
