How To Solve these footbridge problems
33
First, by developing footbridge designs that are
sustainable on the local village level
34

• Then, by starting programs that teach these
  designs on-the-job to local engineers, who in
  turn, teach others.

35
Country Selection A country is selected by
assessing over 50 criteria.

Design

2. We use standardized design manuals. Our
bridges are very low tech all are basically
identical and require no more than multiplication
and division to design.
