U.S. Route 66 and U.S. Route 166 formerly passed through Springfield, and sections of historic US 66 can still be seen in the city. US 166's eastern terminus was once in the northeast section of the city, and US 60 (westbound) originally ended in downtown Springfield. US 60 now goes through town on James River Freeway. In mid-November 2013, the city began discussing plans to upgrade sections of Schoolcraft Freeway (Highway 65) and James River Freeway (Highway 60) through the city to Interstate 44. The main reason is to minimize confusion should there be an incident on I-44 as a detour route.
