Speed limits in the United States by jurisdiction
On February 10, 2017, a bill was introduced to raise the speed limit on select rural interstate freeways and highways to 75 mph. The bill also contains a provision to increase maximum speed limits to 60 mph for all rural highways, roads, and streets that do not have 4 or more lanes of traffic. This bill and one filed in 2018 died in the legislature.
As of March 27, 2018, the speed limit on I-90 from Randall Rd. in Elgin to Mt. Prospect Rd. in Des Plaines has been increased to 70 mph, and from Mt. Prospect Rd. to the beginning of the Kennedy Expressway, it has been increased to 60 mph . I-290 is posted at 60 mph for a few miles near Schaumburg, from IL-72 down to shortly before the I-355 exit.
