This is where to turn South (left onto the road you can see here).  In February you can see the sign; in May, that's not as easy! 

Just follow the arrows on the road and gear down to climb the overpass.  Just as with any hill, cars approaching can't see you.  This is also where you should be mindful of where you are and where any riding companions are, as a little wobble can lead to "road rash" if your wheels collide, and you might be getting a little fatigued by now. 

Then you'll cross route 150, and take the next right on Washington and head back into beautiful Urbana- Champaign!  Hope it's a wonderful trip!
