The male pilot of the 1968 Beecher aircraft emerged unscathed but his female passenger was injured during the rough landing Monday evening, the Racine County Sheriff's Office told the Chicago Tribune.
A sheriff's spokesperson said the aircraft sustained "extensive damage" but did not strike any vehicles on the highway.
The Federal Aviation Administration said the plane was registered to a company called Direct Action Aviation LLC out of Reno, Nev.
Cause of the accident is being investigated.
