“Our interchanges there are obsolete. As that traffic count continues to grow, you start exceeding capacity. Your interchanges get clogged up, then people start having accidents trying to get onto the interstate,” said Bill Frey, program development engineer with the Illinois Department of Transportation.Finally, they're going to look into adding an additional lane around Springfield. That's good news. (But 6.5 MILLION dollars to just study the idea?)
Frey also explained why the roughly six-mile section of I-55 between Sangamon Avenue and Interstate 72 was not six lanes when design work began for the U.S. Interstate 55 Bypass in the early 1960s.
“At that point, Springfield was a departure and destination community. Everybody was coming to Springfield and not going around Springfield,” said Fry.
Perhaps Paul McCartney complained about the lane situation and now IDOT is taking notice.
