For 2 days now I've noticed that (unlike before), the traffic light begins to change when pulling up to Mainland Road (the old Sumneytown Pike) from Wambold Road. This is an AOK solution. What was crazy before was that it was making folks on Wambold wait for a full minute for a green light, with no traffic present on the old Sumneytown Pike. Now the light is changing to green right away.

This now appears to have been fixed, as of about two days ago. The light now starts changing to green right away when pulling up to Mainland Road (the old Sumneytown Pike) from Wambold, rather than making you wait for a full minute with no traffic coming.
