Can't tell you since I have not experienced it. What is the exact issue? I would imagine it is the Left from Prospect onto Cross. THat would be helped by a turning lane on Cross to James and probably solved with a traffic light, but there would again need to be a turning lane Cross onto Prospect.
The issue is a right onto cross mostly, it can get backed up all the way to prospect vines. It seems it only became really bad since williams started being closed on a regular basis. Turning left onto cross is usually not a big deal ppl are nice and let them through.
What im confused is why cross in both directions is only backed up till James, towards prospect it clearly just needs a turning lane onto james but the other direction makes no sense.
Where are you suggesting a traffic light, From prospect it wouldn't help the traffic would have no where to go?
A turning lane from cross onto prospect would help a little, but theres enough room there for ppl to get around those that are turning.
