The new flyover ramp linking the inbound Dan Ryan Expressway to the outbound Eisenhower Expressway will open on Sunday.
The Illinois Department of Transportations says the single open lane will help improve traffic flow and safety for approximately 400,000 motorists that drive through the Jane Byrne Interchange each day. The second lane on the flyover ramp will open after work is completed in the summer of 2018.
The opening requires some temporary closures, officials said.
Beginning at 8 p.m. Friday, the ramp from inbound Kennedy Expressway to the outbound Eisenhower will be closed from Madison Street to Halsted Street. Outbound Dan Ryan traffic will exit at 18th Street and re-enter the inbound Dan Ryan taking the ramp to outbound Eisenhower. The right lane of the inbound Kennedy will also be closed. All lanes and ramps on the inbound Kennedy will reopen by 5 a.m. Monday.
At 11 p.m. Friday, Congress Parkway will be reduced to one lane between Canal Street and Morgan Street until 2 p.m. Sunday, according to IDOT.
Beginning at 9 p.m. Saturday, the right lane of the inbound Dan Ryan will be closed from 26th Street to Harrison Street, said IDOT. A second lane closure will begin two hours later but all lanes will reopen at 11 a.m. Sunday.
Construction on the flyover started in September 2014. This weekend, ramps from the Stevenson Expressway to the inbound Dan Ryan will be restored to two lanes, and all lanes on the inbound Dan Ryan and the Roosevelt Road entrance ramp to the outbound Eisenhower will reopen.
The flyover ramp replaces the existing single-lane, winding ramp with a two-lane ramp and bridge that begins just south of Roosevelt and arches over Harrison, the rest of the Jane Byrne Interchange and Halsted before connecting to the outbound Eisenhower near Morgan Street. When construction is complete the entire structure will stretch about 1 mile, IDOT said.
