A pedestrian walking in a driving lane on Interstate 41 in Winnebago County was struck and killed early Sunday morning. According to the sheriff’s office, a 24 year old Oshkosh man was hit by a semi around 2:45 a.m. Authorities say it appears neither drugs nor alcohol were involved in the man’s death. The truck driver was not hurt, and cooperated with authorities. The crash closed down that portion of I-41 for about six hours early Monday morning south of Oshkosh.
