I'll pass your thoughts on to our construction team -- we still have signal work in the area, so until the project is completed, we will continue to hone the timing. Andrew Gates, MoDOT Communications
We haven't changed the timing between the two ramps from I-44 to Hampton, however, we are probably seeing some heavier traffic due to the various construction projects around the city -so the lanes are heavily loaded during evening rush period. We will put up some signs reminding drivers to not block the intersection, but ultimately, ensuring that they do that is the responsibility of law enforcement. Andrew Gates, MoDOT Communications
Last week, a reader asked: “What are the thoughts on taking one of the [westbound] thru lanes of Big Bend at Shrewsbury and making it a double left or even a shared thru/turn? Some evenings (most) the line for west to south traffic backs up past the RR overpass.” ST. LOUIS COUNTY'S REPLY: The installation of a dual left turn from westbound Big Bend Boulevard on to Shrewsbury Avenue-Key West Avenue would require 30 feet of pavement width on south-bound Shrewsbury Avenue. This pavement width is needed to limit the likelihood of sideswipe type accidents when two vehicles are simultaneously turning left. There is presently only approximately 25 feet of pavement width on southbound Shrewsbury Avenue to receive this requested westbound dual left turn.
Also, in order to install a second left turn lane to facilitate this requested dual left turn, we would have to either (1) take a through lane away from westbound Big Bend Boulevard and restripe this lane for a second dedicated left turn lane or (2) modify the existing inside through lane to be a shared through/left turn lane and split phase the eastbound and westbound Big Bend Boulevard signal phases. Split phasing the eastbound and westbound signal phases would require separate signal phases for eastbound and westbound Big Bend Boulevard – meaning that there would be no concurrent GREEN time for east- and west-bound traffic flow. Either removing a westbound through lane or split phasing the eastbound and westbound movements at this intersection would decrease the overall efficiency of this intersection.
For the reasons listed above, we do not recommend providing a dual left turn on westbound Big Bend Boulevard at Shrewsbury Avenue-Key West Avenue. DAVID WRONE, ST. LOUIS COUNTY
The Washington Ave streetscape project is scheduled to be complete by fall of this year and is being managed through the St. Louis Development Corporation (SLDC). I can check on the status with them at the intersection you noted.
The Loop Trolley contractor is maintaining signal timing during the construction of the project. I will inform them of your observations. Thanks for the heads up.
The Kingshighway bridge is anticipated to be open to traffic by the end of April.
You are welcome, Patrick! David Wrone, St. Louis County
The work on southbound Route 67 is just a high-friction overlay that will help improve how tires grip on that section of roadway. Shifting traffic will help get the job done quicker. We will not be making any changes to the medians as a part of this project. The project should just take a few weeks to place the new overlay. Andrew Gates, MoDOT Communications
Likely at this location there was limited sight distance which prompted the no right on red installation (I believe while construction was occurring at a corner there). MO law does not specify that left turns on red are an allowable movement.
