Probably not the official I-55 Yelp page but hopefully this review may help someone and it may be moved to an existing I-55 page. I've driven the entire 293 miles countless times so I can explain pretty thoroughly everything you can encounter.... If you're entering from St. Louis, there's a bit of traffic you might fight through until you reach mile marker 15... The entire drive is smooth through Springfield (as long as you don't get follow business 55) all the up just to the southern border of Bloomington where there may be some slight confusion. After that, I highly recommend taking a stop at exit 197 and visiting the Wallys gas station which is like a Bucees but also recommended stopping there before the gas prices start jumping way up too! Continuing north bound traffic is smooth until you get past exit 250 at the I-80 interchange where you enter the Chicagoland area where traffic builds up with each passing interstate connector you go through with exit 269 to connect you with I-355 where going north is awful. Then with where heading in either direction is bad with exit 277 with people either going toward Wisconsin or Indiana then followed by exit 290 where you're faced with even more traffic going north to Wisconsin or Indiana. If you drive through that, your drive will be smooth for the next few miles Exit 293 will conclude I-55 and split into lake shore drive and you can choose what adventure you want to do from there. For my trucker friends, if you're curious about weigh stations to plan your drive through, from north to south you have 3 weigh stations. One in between exits 267 and 263.... One past exit 110 and the last one past exit 15 in Collinsville.... From South to north there are 2 weigh stations, one past exit 52 and another between 263 and 267... Rest stops are lousy, plenty of route 66 tourist attractions. Some cool towns worth stopping at. read more
