I both live here locally and travel extensively to races, so here's what I would do, if I didn't know the area well, but knew the current situation.

First off, Davis Avenue is closed right now for construction.

Coming in: Do as you normally would. There are detours that will get you around the construction zones coming in from the East, but they'll leave you just as likely to get railroaded or leave you just as delayed getting through evening city traffic. And the railroad tracks, in this situation, are ones that trains occasionally stop and sit.

Leaving: Going Westward, do as you would normally. Going Eastward, take I-70 West to the Darwin Road exit (less than 5 miles up the road). Go up the ramp, cross back over the Interstate, turn left on to the I-70 East entrance ramp and enter I-70 East and proceed East.

Or you can go to the first intersection North of I-70 on US41. This is Margaret Avenue. Turn right at the Marathon station. This street runs parallel to the Interstate and goes all the way to Hwy 46. Turn right, go under I-70 and you'll see the I-70 East ramp.
