The schedule changes, the map changes with it — no second letter, no outdated announcement.

The Works Map shows where work is taking place, what disruption is expected, and how far along the work has progressed — per location, always current. If the schedule changes, it is updated and anyone who has signed up automatically receives a notification. Someone living at the start of the street sees different disruption from someone at the end; the map makes that distinction without everyone receiving the same generic message.
