The Chicago Transit Authority's Blue Line operates in the median of I-190 for the highway's entire length.

Interstate-standard freeway ends roughly at the ramps to the upper (departure) and lower (arrival) loops.

Both exit numbers and mileage markers on roadside light fixtures ascend traveling westbound.

[3][5] In late 2005, the intersection with Mannheim Road was reconstructed to remove unsafe conditions and bring the route closer to Interstate standards.

This created a hazardous condition, often leading to high-speed crashes should drivers waiting on the ramp become impatient or underestimate the speed of westbound traffic.
