There are two clearly marked turn lanes when making the left onto E Chestnut from Matlack/Gay St. As soon as you turn onto Chestnut the lanes disappear and road narrows (mostly because of parked cars) and there is no indication that you are suppose to merge. Are there two lanes or one? Which side merges into the other? Is one lane a turn lane?
A little paint and a sign would go a long way here. I've seen so many people over the years nearly get into accidents (and fights) over who has the right of way.
