I have used the Normal supercharger many times on trips from St. Louis up to Traverse City Michigan and also trips to Chicago. The Normal parking garage also has chargers for other EV's and Normal is an interesting little college town. Most recently, I used the Normal supercharger on Sept. 20th. However, construction to the south of the Parking facility required extensive detours to gain access to the garage. As is typical, the Tesla route finders was unaware of such construction work. Once I drove across a new bridge across the Mississippi than Tesla didn't think existed, although Google maps was completely aware of it. Will the new update fix those issues? I sure hope so.
For regular users of the Normal supercharger, it would be nice to get updated information regarding the construction around the Parking garage. The garage is accessible, but suggested routes from the south will lead you to dead-ends.
