120 minutes: A fourth sign at a real time cost
Opening agreement: 10 minutes
Inspect the grid and hear changed journeys: 30 minutes
Allocate signs and make the clinic route: 40 minutes
Choose a permanent map and public oversight: 30 minutes
Closure and debrief: 10 minutes
The extra time can fund salvage and a market sign while retaining the new layout. Studying the original arrows as well uses the remaining spare turn and makes that combined plan too late; choose which civic benefit matters.
