Groundbreaking on the Hillsborough Street revamp (phase 1) is in three weeks. There’s an open house tomorrow, from 4 to 7 p.m., for folks to catch up on what’s planned, when, the effect of construction on traffic, etcetera. It’s in the Hillsborough Street Partnership’s new headquarters, which is in the office space attached to the back of the Mini Mart strip mall — across from the Bell Tower and a few doors east of Sadlack’s. (Office address is 2 Maiden Lane). Drop in when you can. Bring fond memories … or put them here, if you like.
