The choice of bridge is determined by many factors including length of span, available materials, cost, geographical terrain, geology, available work force, and weight needs. Truss bridges are made up of small pieces that are easily transported and put into place. They are economical to build because they make efficient use of materials. Suspension bridges make long spans possible. They can be as simple as ropes and wood planks hanging over a creek or as elaborate as a concrete and steel cable structure spanning a wide river. Concrete girder bridges are the most common bridges built today in Northwest Arkansas.
