There's some confusion over which interstates and highways the new 70 mph speed limit will apply to. Officials are trying to figure out if the higher speed limit is solely for rural areas or if urban areas are also included. According to the Chicago Sun-Times:
"SPRINGFIELD — Illinois raised its speed limit Monday on its vast interstate and tollway highway system to 70 mph.
But don’t go flooring it just yet until the politicians that put this new law on the books figure out whether higher speeds were really meant for the Dan Ryan, the Stevenson, the Tri-State and urban super-highways like them – or just the ones cutting through the state’s corn and soybean fields Downstate.
Gov. Pat Quinn, who defied the advice of members of his own cabinet, signed the higher speed-limit legislation into law Monday but insisted the move from 65 mph to 70 mph will affect only rural interstates when it goes into effect Jan. 1."
