Heads-up to all who hope for a weekend drive on the Windward coast, which has been hobbled by contraflowing traffic. Make sure you’re clear of the Kahana Bay zone, the site of a water-main break and damage to the road bed, by Sunday at 6 p.m.

That’s when the state is going to shut Kamehameha Highway completely, fronting the park, until 4:30 a.m. Monday. During the closure, ending before morning commutes, some critical repairs will be made. It’s a good thing all this didn’t happen during surf season.
