Grand Valley East Section dropped 2 chunks of course from the main Grand Valley Speedway - directly after the first split point after the first hairpin, the track went straight instead of sweeping left, and rejoined into the long sweeping left-hand turn that follows the tight hairpin on the Speedway circuit. The other piece was considerably larger - following the first tunnel where T2 is, the track goes right and comes out that road you saw leading on to the main straight before the final kink - East Section bypasses the entire second tunnel, bridge, third tunnel and final esse.
