1/24th scale is the largest scale track and it does cost a bit more for the required light bridge due to span and materials used for a robust light bridge....
We will need to know the tallest car or truck when slotted...we then add about 1/2 inch to 1 inch for extra clearance of the light bridge...You can include a note at check out or contact us by email to provide that information for the proper clearance.
Also available for 4 lane layouts for a bit more $
