Here are some pics. The track is 28 foot long and 8 foot wide. Using b.yinglings program and I used a 42 inch TV so everyone can see what is going on. You can switch between running digital on the road course or digital on the oval by flipping 2 non operational lane changers.
Views from each end
Here is how it funnels onto the road course off the oval.
And off the road course and back onto the oval.
