Traffic cleared up in the westbound lanes of the H-1 Freeway after being clogged for over an hour after debris apparently fell off of a vehicle near the Gulick Avenue overpass.

Just before 2 p.m., the Hawaii Department of Transportation tweeted: “HDOT inspectors have looked at the Gulick Avenue overpass and there is no structural damage. Traffic is clearing through the area on the H1 Fwy as all lanes are open.”

The incident follows a March 4 collision between a vehicle and the Gulick Avenue overpass that forced the closure of several lanes of the H-1 Freeway.

Tim Sakahara, spokesman for the state Department of Transportation, said after DOT inspectors did not find any damage, they initially did not think the overpass had been struck.

However after reviewing photographs, they realized that the bottom of the overpass had been scraped by a box truck being carried by a flatbed truck.

Westbound traffic was delayed before 1 p.m. after debris apparently fell off of a vehicle, possible during a collision, he said.
