A beam bridge is a strong, horizontal structure that rests on two end supports, and carries traffic by acting as a beam. Beam bridges are often used for heavy cars and trains to pass, and some are also built for people to walk on. Beam bridges used to be made from wood and were called log bridges. They are most commonly now made out of steel. Beam bridges are usually placed over highways or gaps in the earth so people or cars can cross over them.
