ABSTRACT:
A plurality of sections of portable roadway are removably interconnected for use during periods of adverse weather conditions during which soil conditions are such that it is impossible to build a permanent road, or when the economics are such that a temporary road is advantageous. Each section consists of a hardwood frame which is connected to and supports a plywood surface. At the front and rear of each section, a transverse stiffening bar extends through and laterally to the side of the section. Connecting members are attached between the free ends of these stiffening bars. In the center of each section, a lifting bar is disposed to aid in removal and placement of the sections in an expeditious manner.
