A section of Tantalus Drive on Oahu is shut to all traffic after storm damage, a headache for drivers and hikers who use the route.

• A retaining wall about ten feet high gave way during the recent storm near the 4.5 mile marker.
• The collapse damaged roughly 120 feet of road, forcing a full closure to cars and people on foot.
• No homes sit in the damaged stretch, so the impact is limited to access and traffic.
• The city says the wall has to be rebuilt from scratch, not patched.

Outlook: Expect the closure to last a while, since a full rebuild of the wall and road is needed before the route reopens.
