I work at GE Healthcare on Shelburne Road. In recent weeks, I have noticed significant traffic backups between IDX Drive and 189. It is particularly bad at normal "rush hour" times, but also at times when it used to be ok. I don't have enough data to say for sure, but it doesn't seem related to the usual spike in seasonal traffic. Is there anything that can be done to improve the flow on the main road? It was pretty good in late winter/early spring from what I recall.
