2/10/15 2:00 p.m. Yesterday DPW plowed main roads, secondary roads and parking lots throughout the day. We treated main roads and collector roads last night, finishing up around midnight. Crews were called in to treat the mains with a salt/sand mixture this morning at 5:00 AM this morning. Last night/early this morning intersections on Rt. 28 at Bearses Way, Strawberry Hill Road and Putnam Ave were widened. Today we are again plowing all of the secondary roads. Salt supplies are getting low. We have 6,000 tons on order.  We will mix the remaining salt with sand until its gone, then go with straight sand. Our salt supplier is unable to estimate date or time of delivery. If the salt vendor allows, we are intending to contract two tractor trailers today to travel to Chelsea and pick up approximately 70 tons of salt, which is the maximum they will let us pick up.
