An apparatus includes an arch-support system configured to support an archway above a work surface during construction of the archway. A rail assembly is configured to selectively receive and support the arch-support system in such a way that the rail assembly, in use, supports the arch-support system once the rail assembly selectively receives the arch-support system.

A formwork for constructing an arched structure comprises a first end panel and a second end panel. A plurality of longitudinal members extends between the first end panel and the second end panel. The longitudinal members are arranged in an arched formation and the longitudinal members slope between the first end panel and the second end panel. The formwork may have rollers disposed along lengths of the longitudinal members.
