Arch Truss Bridge
The Arch Truss design is one of the most frequently used designs in history. Construct the end supports and then
add the deck. Tie cords from the base of one end support to the base of the other end support. Next, add the arch
and suspension beams. Use Flat 3 X 4 members to cross brace the deck at the point where it joins the top of the end
supports. Use cord to cross brace the bottom sections of the arch. Finally, use Track Clips to attach the Coaster
Track.
Connect the
center of the
arch with
Straight Con-
nectors and a #1
Beam.
Use Sliding
Connectors and
#1 Beams to
suspend the
center of the
arch.
