Part of 11th Avenue in Kaimuki is shut down after a restaurant roof caved in, bad news for the business, nearby traffic, and four injured customers.

• The roof at the Happy Days restaurant collapsed Tuesday, hurting four women in their 80s.
• City inspectors found a key interior support beam gave way, and the wall along 11th Avenue is now leaning.
• The city closed the stretch of road next to the building over fears more of it could come down.
• The restaurant stays closed while the owner works out what happens next.

Outlook: The road is likely to stay closed until engineers decide whether the building can be shored up or has to come down.
