Authorities say they're investigating why a small plane landed on a busy interstate north of Minnesota's Twin Cities.

The single-engine SportCruiser plane landed in the southbound lanes of Interstate 35 near Wyoming shortly after 10 p.m. Friday. Authorities were forced to temporarily close both sides of the interstate, which was busy with Fourth of July weekend traffic.

Some fuel leaked onto the road before the aircraft was removed around midnight, and police said the pilot had minor injuries. No one else was hurt.

A Minnesota State Patrol spokesman says it's unclear whether the plane crashed or made an emergency landing.

Wyoming is a city of about 8,000 people 40 miles northeast of St. Paul.

Federal Aviation Administration records show the plane was registered in 2007 to Leonard Nolden of Isanti, Minnesota.
