One person suffered minor injuries this evening when a small plane landed in the westbound lanes on Interstate 580 near 164th Street in the Ashland neighborhood of unincorporated Alameda County just west of Castro Valley, authorities reported.

The single-engine Cessna 172 made an emergency landing on the freeway about 6:45 p.m. tonight after the pilot reported a rough-running engine, said Ian Gregor, a Federal Aviation Administration Pacific Division spokesman via email.

The plane's registered owner is Fly Fe LLC, based in Reno, Nevada. The tail number of the aircraft is N9679A.

Gregor couldn't say tonight where the plane's trip began, or where it was headed when it made the emergency landing.

The plane was not damaged, nor were any vehicles on the freeway hit by the plane.

At 8:15 p.m., the plane was still blocking the right westbound lane of the freeway, said CHP Officer James Evans.

There were two people in the plane, Evans said, and one of them reported a "complaint of pain."

Westbound freeway traffic backed up quickly after the landing.

The CHP issued a "Sig Alert" in the area, denoting a major traffic tie-up that would take time to clear up.

The Alameda County Fire Department Tweeted video of the incident:
