Bridging Machines (S03E06)

Brothers in Arms face off against the victor of Bomber (either 3 Revs a Minute or Mothers of Invention) in a competition to design a vehicle that can transport all four team members over a 30-foot chasm. This vehicle must also be able to set up a bridge and pull it back once the team has crossed. The Brothers opt for a van-style bridge solution, while their rivals decide to utilize bicycles.
