Recent and Future Activity
- There is ongoing construction to upgrade U.S. 61 (where it is multiplexed with U.S. 40) to a controlled-access freeway. The current freeway ends at Route K just west of Weldon Spring and the construction will upgrade U.S. 61 to a freeway to Interstate 70 at Wentzville. When construction is finished, this freeway also will be signed as Interstate 64.
- U.S. 61 between Wentzville and Wayland are planned to be gradually widened and upgraded to expressway status . It is unclear whether the entire length will ever be upgraded to freeway status, although it is expected that the entire highway will be 4 lanes wide to the Missouri-Iowa border by 2008. As of 2006, the route is expected only to be a freeway as bypasses around towns. This route will eventually form a part of a more direct route from St. Louis, to Cedar Rapids, Iowa to Waterloo, Iowa to Saint Paul, Minnesota as part of the Avenue of the Saints .
