Kawaihae Harbor is the Big Island's busiest cargo port, where Pier 2B has been open since Tuesday afternoon after cracks opened up during Sunday's earthquakes.

Workers have paved over cracks and "they didn't seem to find any structural damage," said Scott Ishikawa, spokesman for the state Department of Transportation.

"It's going to be a little tight having Matson and Young Bros. working the same site, but all the parties understand the situation," Ishikawa said.

Divers continue to check Pier 1 for structural damage and crews may have to remove the top surface of the pier "just to see if there's any structural damage underneath," Ishikawa said.
