    Abstract: An intersection adapted for engagement with a toy racetrack to provide an combination jump and overcrossing intersection for vehicles traversing the racetrack. The device features first and second supports engageable with inline pairs of track thereby forming two pathways across a jump formed by a gap in the middle of the device. The first support is in a translatable engagement with the second support between a first position where vehicles crossing the gap at the same time would collide and a second position forming a second path where vehicles jumping the gap are on different trajectories.
