ABSTRACT:
The present invention is a floating highway unit which has a structure which facilitates both removal from linkage in a series of units forming the highway, provides for simple alignment of the units during assembly, and also allows vertical movement caused by tides and waves. Protection is provided for the highway by use of a partly floating barrier, for damping wave motion, thus substantially reducing the amount of absolute and relative movement of the floating highway units. Each of the floating units of the present invention is comprised of a generally rectangular horizontal pontoon including provisions for floatation of the pontoon, the pontoon having a centrally located horizontal tongue extending outwardly from a short side of the pontoon whereby the top surface of the tongue is an extension of the top surface of the pontoon. A recess is located in the opposite side of the pontoon having a shape for enclosing the tongue which matches the shape of the tongue. A slot extends across the width of the tongue, and a pair of in-line slots extends across at least part of each of the opposite sides of the pontoon into the recess on opposite sides of the recess respectively. The later slots are coextensive with the slot in a tongue of an adjacent pontoon when it is enclosed in the recess. A key is inserted in the coextensive slots to retain the floating units together.
