Answer 1

Beam bridges are often only used for relatively short distancesbecause, unlike truss bridges, they have no built in supports. The only supports are provided by piers. The farther apart its supports, the weaker a beam bridge gets. As a result, beam bridges rarelyspan more than 250 feet (80 m). I hope it helps you
