YOU WILL LOVE this video of central Iowa’s US 30, filmed in 1959 to show congestion and the need for road improvements.
Highway Relocations was created by the Iowa State Highway Commission (ISHC), now IDOT, to show the downside of gas stations, rest stops, and the skinny two-lanes they populate. Filming started just east of State Center at the junction of Iowa 64 (now Iowa 330) and US 30 (the Lincoln Highway) and continued west along US 30 through State Center, Colo, Nevada, and Ames, ending just west of Boone. The film is 16 minutes long and covers 55 miles. {Note: Please read the comments for more info on the cars and the year it was filmed.]
