Weekly Jigsaw Puzzle

CTA Red-Purple Bypass

CTA Red-Purple Bypass

On Chicago’s north side, a new flyover bridge is the solution to years of bottlenecks and delays at a critical elevated rail interchange--and steel was the perfect material to make it happen!

In completing the Red-Purple Bypass (RPB), the project team behind the Chicago Transit Authority’s Red and Purple Modernization Project overcame tight urban spaces and strict displacement tolerances. The result? A new single flyover track that carries the northbound Brown Line over the four mainline tracks, increasing the speed and efficiency of the other trains using the interchange.

Find out more about this project at, and while you’re at it, assemble a jigsaw puzzle featuring the flyover girders and straddle beam at!
