PORTLAND, Ore. (KOIN) — A stretch of Southwest Tualatin-Sherwood Road is closed Wednesday after a semi-truck lost part of its cargo of heavy steel plates, police said.

The crash happened just east of SW Martinazzi Avenue, police said in a Tweet at 12:40 p.m. Traffic cameras show the scene where the semi is reportedly blocking the right westbound lane.

SW Tualatin-Sherwood Road is closed at SW Nyberg Street. Drivers are being redirected onto Nyberg from Martinazzi Avenue then back onto SW Tualatin-Sherwood Road, which has been limited to one lane.

Authorities said the road is now expected to be closed for two hours.
