According to Section 6 of the FIRST manual:

The OVERPASS structure extends across the minor axis of the TRACK. The OVERPASS is constructed of 1-1/2 inch O.D. steel pipe and connecting hardware. The OVERPASS is supported by three vertical supports – one at each end, and one in the center (the center support is also part of the LANE DIVIDER). The vertical supports rise above the horizontal portion of the OVERPASS, to a total height of eight feet and four inches. This is to help prevent TRACKBALLS from rolling off
the OVERPASS and exiting the arena, or rolling across the center of the LANE DIVIDER. The horizontal portion of the OVERPASS is 6-1/2 feet above the floor. The rails of the OVERPASS are spaced 32 inches apart (center to center). On each side of the OVERPASS, a series of spacer bars define three TARGET LOCATIONS on the OVERPASS. The TARGET LOCATIONS are sized to allow the TRACKBALLS to rest within them.

This is also covered in the 2008 FIRST Official Drawings
