Traffic is split in some places, i'd stay out of the "express lane" since its only a single lane. Take 294, it wasn't bad at all (late last sat. afternoon) when i was returning from gurnee down to 290.
Thanks guys. I pretty much always expect construction in Chicago -- just too many miles of Highways to not be. The construction on 294 wasn't too bad. On the way north this morning I jumped in the first express lane and regretted it . . . right up to a fairly fierce backup when the two other lanes went down to one.
Always love getting down to Chicago -- although it had been a while since I had been in the Oak Brook area -- lots of even more new development since I was last there!
