On Thursday, Governor Bruce Rauner announced a new proposal to address congestion on the Stevenson Expressway, aka I-55, by adding lanes. The construction would be financed via a public-private partnership, and the new lanes would be tolled. Revenue would go to the concessionaire, allowing them to recoup their investment.
The so-called “managed lanes” would be an option for drivers who are willing to pay a premium to bypass traffic, while the existing lanes would not be tolled. Some local transportation exports and advocated lauded the plan as a creative way to address congestion woes. But others argued that our region’s focus should be on providing better alternatives to single-occupant vehicle commutes, rather than simply building more capacity for them.
The proposed lanes would cover a 25-mile stretch of the Stevenson between the Dan Ryan Expressway and the Veteran’s Memorial Tollway, a segment that carries about 170,000 vehicles a day. The plan calls for adding at least one lane in each direction, at an estimated cost of $425 million. The P3 model would need to be approved by a majority of state lawmakers.
The new lanes would feature “congestion pricing” – the toll price would vary according to the number of cars in the managed lanes, as well as the rest of the expressway. Rauner said it’s possible that drivers with one or more passengers might be allowed to use the new lanes without paying a toll. The state hopes to finalize a design by this spring and start construction by late 2017.
The Metropolitan Planning Council pushed for several years in Springfield for legislation to enable this kind of public-private partnership, which passed in 2011. MPC executive vice president Peter Skosey said his organization applauds Rauner’s proposal, adding that adding capacity to I-55 is listed as a priority in the Chicago Metropolitan Agency for Planning’s GO TO 2040 regional plan.
“Experience shows that simply adding another regular lane will not ease congestion in the long term: once that capacity is there, it will just fill up,” Skosey said. “Putting a variable-priced toll on that lane lets you manage demand and keep it free-flowing. If you’re really in a time crunch, you have the choice to take that lane.”
Skosey argued that the new lane would also make taking the bus a more attractive choice. “[Pace’s] current Bus-on-Shoulder service has been incredibly successful, but it isn’t able to use the shoulder for the whole corridor and it’s limited to 35 mph. This lane would give it a continuous path and let it go as fast as 55 mph, improving reliability and opening the door to more frequent service.”
Steve Schlickmann, the former head of UIC’s Urban Transportation Center, agreed that the governor’s plan makes sense. “The combination of high congestion in regular travel lanes and insufficient growth in federal and state funding to maintain Illinois roads and transit, makes I-55 managed toll lanes a reasonable approach to address congestion and to help pay for I-55’s on-going maintenance needs,” he said.
