Join Linda Wilson of the Missouri Department of Transportation, Todd Waelterman of the St. Louis Streets Division and David Wrone of the St. Louis County Department of Highways and Traffic each Wednesday at 1 p.m. for the Road Crew, an online chat about area traffic and transportation issues. Submit questions at stltoday.com/chat. Transcripts of past discussions are available. Here is an excerpt:

Ken Kuhlenschmidt: Regarding the restriping of Highway 370 eastbound between Highway 94 and Earth City, yes, it was redone last week, but now, when entering at 94 eastbound, the solid white line extends the entire length of the right exit-at-Earth City lane. The previous broken white line is gone. All four lanes are solid white-lined now, until past the Earth City exit. What is the exact significance of a solid white line like that?

Linda Wilson: A solid white line typically is advisory that you should stay in your line. It is not illegal to cross it, just advisory. Because we have temporarily restriped 370, we have chosen to make the lines solid so they are more visible.

Steve K: Are there any plans to rebuild the St. Charles Rock Road bridge over the Missouri River into St. Charles? We could always use another bridge there.

Linda Wilson: No. The old Highway 115 bridge (St. Charles Rock Road) was removed because the Highway 370 bridge was built to replace it. The Highway 370 Missouri River bridge carries about 65,000 vehicles per day, so there is still a lot of room for it to carry more.

David: Going back to the "painted island" on North Hanley approaching Dunn Road, any consideration on getting rid of the island so that traffic can flow on to the left turn lane to westbound Dunn? Traffic can get a bit congested as the people want to go left vs. straight.

Linda Wilson: The painted hashed island could be removed so that you have three lanes at the signal between Pershall and the I-270 ramps. I can see your point that it would allow the cars to line up with two lanes for northbound Hanley and then the left lane to start forming for the left turn at Dunn. It's a little more complicated than just removing the paint. We have to adjust the overhead signals and probably some signage. I will have our traffic department look into it if this is possible. I also want to add that we may not be able to have three lanes going northbound because then we can't allow yielding left turns from southbound Hanley onto the eastbound I-270 ramp. All of this will be looked into and I will post an answer hopefully next week.
