I can't believe the following hasn't been fixed in the several years since the Main Street Center opened:

Northbound Rt 100 traffic blocks the Rt 30 West bypass off-ramp, so that only the far right lane on northbound Rt 100 is open. Of course, most drivers coming off 30 Bypass West who turn right (north) onto 100 won't make use of this right lane, probably because they want to turn left soon. So, they just advance a few feet towards their center lane, blocking the remaining cars on the off-ramp.

Stop-gap solution, since PennDOT seems helpless to figure out how to re-time the lights: FILL IN THE AVAILABLE SPACE IN ALL OPEN LANES, THEN WORRY ABOUT MOVING OVER TO THE LEFT DURING THE NEXT 100 YARDS BEFORE YOU GET TO COMMERCE BLVD! DON'T INSIST ON ENTERING YOUR DESIRED LANE RIGHT OFF THE RAMP (especially if it's already blocked by cars). THINK OUTSIDE THE BOX!

I travel up and down Rt 100 8-10 times a day and I completely agree that all the stop lights that are not in sync are extremely frustrating... even more frustrated when you have a 4 month old in the car!!!

Put in some traffic circles and get traffic moving! All these lights are just causing back-ups

Traffic circles on rt 100????? the amount of truck traffic and stuff like that would be such a smart idea plus 90% of the people in exton area would still go in it and cause some accidents that would leave you to sit in traffic longer. SO rt 100 stays the way it is god forbid there is a bad accident they can use one lane on the opposite side to run traffic. The roadway has been like this sinced main street opened, your seeclick fix is not going to have any push for something that will never change. Also ive only ever seen this work once and it was to try and get tall shrubs cut so someone could see around the corner and it was only taken care of after a township codes guy saw it and ordered that stuff to be cut back and that was 2 years ago in west bradford
