A new Briggs & Stratton Motorplex for go-kart, Legends car and junior dragster use has been built inside the existing 4.0-mile road course at Road America, near the carousel. The new Motorplex includes a 1/5-mile paved oval, a 1/8-mile drag strip, and a short road course. The new road course does not run on any part of the existing road course or new drag strip, except for using the drag strip as a pit lane and access road. The new road course has eight different possible configurations.

Other changes to the Road America infrastructure include a new gate added for the convenience of competitors, additional on-facility camping spaces, trees thinned out in spectator areas for better viewing, new grandstands, an expanded main paddock, and a new fiber-optic network installed around the track and in the media center to help with audio, video, and communications.
