Gulick Avenue in Honolulu shuts down for a full year starting September 21, bad news for drivers but manageable for people on foot or bike.

• The street closes so crews can tear down and rebuild the Gulick overpass.
• A temporary pedestrian bridge will stay open for walkers and cyclists.
• Work runs weekdays from 8am to 4pm and will be done in phases.
• Drivers in the area should expect detours for the next 12 months.

Outlook: The closure holds for about a year while the overpass is rebuilt, with traffic patterns shifting as each phase starts.
