It has been a challenging week for many Central Oahu commuters who normally use a busy Wahiawa bridge.

The Karsten Thot Bridge was closed Monday and Tuesday. The closure lead to traffic delays for some drivers, but the state is changing the bridge's repair schedule to try and get things moving for motorists.

In July, an inspection found problems with the 80-year-old Karsten Thot Bridge.

"Corroded rivets and steel connection plates," said state bridge engineer Paul Santo.

Inspectors said the bridge couldn't handle loads over 10 tons until those problems were fixed.

"Right now, we need to repair the bridge. It's critical for safety reasons that the bridge gets repaired," said state Transportation Director Glenn Okimoto.

Because the bridge was able to carry cars, pickup trucks and city buses, some residents want to know why it was completely shutdown this week. Santo blamed it on the big vehicles that refused to follow the rules of the road.

"The compliance of the 10 ton load limit was not being followed," stated Santo.

The shutdown had some drivers stuck in traffic for hours. Adding to the frustration, some residents felt the state did not give residents enough notice of the emergency closure.

"I thought the bridge repair work could be coming soon. I had no idea it was coming Monday morning, so I was caught by surprise," said Wahiawa resident Danielle Utrera.
