Happy New Year! Spent part of the holidays going through a few thousand photos covering Illinois Interstates to fill in some page gaps for I-57 and I-80, plus finally make a page for Interstate 180.
Interstate 57 north at the Tri State Tollway (I-294) at Markham, Illinois. The first of six ramps at the exchange opened in 2014. 06/20/15
Prior to 2014, Interstate 57 and the Tri State Tollway (I-294) crossed without any access. This changed with Phase 1 of the I-294/I-57 Interchange Project, which added a flyover from I-57 north to I-294 north, a two lane ramp from the Tollway south to I-57 south, and a half diamond interchange along the Tollway with 147th Street (to provide connectivity with I-57 to the east). Started in Spring 2019, Phase 2 completes the interchange with the addition of four ramps including a flyover from I-57 south to I-294 south. Work runs to the end of 2022.
