If your morning commute brings you in from outside Saint John, there is a change coming to Highway One you need to know about. First of all, work on the One Mile Interchange is ramping up at Exit 125 at Crown Street and also the Allison Road and Wright Street Intersection beginning tomorrow. Then later this week and the first of next, the Crown Street Off-Ramp, Exit 125, will be permanently closed depending on weather. Traffic will be directed to a new ramp to access Allison Road.
