Crews extinguished two spot fires Tuesday along the eastbound side of Highway 118 in Simi Valley, officials said.

The blazes were reported just before 3:17 p.m. near Kuehner Drive, according to the Ventura County Fire Department. Initially, it was thought that the fires were near Rocky Peak close to the Ventura and Los Angeles county line, authorities said. Crews from the Los Angeles city and county fire departments responded to assist, officials said

The fires burned about 2½ acres of brush and were declared fully contained by 5 p.m., officials said. No structures were threatened and no injuries were reported, authorities said.

The incident caused a major backup for motorists traveling east on Highway 118. All affected lanes of the freeway reopened about 6:45 p.m. and firefighters had left the scene.

The cause of the fires remained under investigation.
