Springfield (AP) — Illinois voters will get a chance to consider a constitutional amendment aimed at preventing funds collected for transportation projects being used for other purposes. It’s the only lawmaker-generated measure that’ll be on the Nov. 8 ballot. Legislators approved the plan Thursday. Democratic state Rep. Brandon Phelps sponsored the so-called “lockbox amendment.” He says it’ll secure more money collected from transportation-related fees like tolls for infrastructure and create jobs. The Illinois Chamber of Commerce backs the measure, saying over $6.4 billion has been swept from the state’s Road Fund since 2003.
