Illinois Roads - I-80/294
I-80 ad 80/294

EB on the I-80/I-294 multiplex at the IL 1 cloverleaf, center photo courtesy Doug Kerr and the other two courtesy Scott Colbert. I-294 changes from north-south (as you'll see by clicking on the link at bottom to visit that page) to match I-80 for their brief marriage. The duplex is pretty unnecessary, since I-294 ends when I-94 joins I-80 in a multiplex into Indiana, but Illinois wanted the 294 number to link to I-94 on both ends. Besides, I-80 is known as the Tri-State Tollway for that multiplex, and the one-road one-number principle supports keeping I-294 on the Tollway.

This is the Illinois 26 referenced in the third photo above, and this photo was taken just south of I-80 by Michael Summa, but in 1978.
