The guideway is made up of an outer aluminum extrusion and is filled with a
prestressed I-beam made of reinforced concrete. It is an equilateral
triangle, 14 inches to a side. The guideway is supported by steel piers that
are 12 inches in diameter, similar to some of the newer poles that hold up
power lines.
