This intersection was poorly designed from every direction a person drives. It needs more than a left turn signal it needs to be completely revised.
-Leaving the shopping center the straight lane is shared by the left turn lane. Most intersection have the right turn lane shared with the straight lane.
-The median on the Walnut St side continuously confuses those unfamiliar with the area causing them to drive up the wrong side of the road.
-When driving down Township Line Rd towards Royersford, the right turn only lane is often confused for a straight lane causing people to cut you off abruptly when they realize it is a turn only

A left turn light would be great, but i think that ever simply repainting the road so the straight traffic is shared with the right turn lane would correct the problem.

Agree with Jason somewhat -- The largest part of the problem is the lane alignment. They clearly didn't re-measure traffic patterns as they should have after the shopping center gained traffic. Given 3 options and 2 lanes, the segment of the pattern with the largest amount of traffic should be given its own direction, and the other two combined. This is standard practice!

Not only does almost no one ever turn right there, but *no one would ever need to*. Think about it -- If you were going to go south on Main into Royersford, you would have exited the shopping center along the south end. There is no reason for a right turn lane to even exist here.
