ABSTRACT:
A flat-formed arch ring unit includes a linear array of voussoir portions connected along their upper edges. The unit is then archable. A method is provided for forming an archway including the steps of arching one or more the flat formed arch ring units and locating them between two or more foundation blocks or the like. This provides a simple yet effective process and unit for forming an archway. With ease of production, shaping and transportation, making new archways or carrying out repairs of existing bridge archways is significantly faster and cheaper, minimizing disruption and delay to traffic.
