CHICAGO -- The Illinois Department of Transportation says it's one of the worst bottlenecks in the country: The Byrne Interchange is undergoing a major overhaul, making traffic pretty miserable this weekend.

The inbound and outbound Congress Parkway are currently closed at the Byrne Interchange. Starting tonight at 8 p.m. Saturday, both directions of the Kennedy and the Dan Ryan between Ohio and 18th will be down to one lane, with all lanes closed for 15-minute intervals from 10 pm. Saturday until 10 a.m. Sunday.

Things are expected to return to normal by the Monday morning rush, but the same closures will return next weekend.

The inbound Kennedy ramp to Congress Parkway is also closed through the end of August as part of the Byrne Interchange Reconstruction Project.

IDOT is installing steel beams to support the deck of a new flyover bridge.

Even some of the side streets are slow going. Public transportation the best option traveling downtown. CTA will be adding extra rail service this weekend.
