I've also submitted requests to Brookline ClickFix repair these potholes, then discovered that Rt 9 is a state road so each town is not responsible for maintenance. Finally found a Mass DOT number to call. June 29th, and again today, called 857-368-6100 and requested the "maintenance office" to report potholes. If you could call also, that would help to get them to recognize that many are having the same problem. Thank you.
