Hancock was involved in developing the initial design of reinforced
concrete Pipe Arch (RCP-A) culverts for use in the State of Minnesota and has been
manufacturing precast concrete Pipe Arch culverts since 1960.
With superior strength and durability of precast concrete, precast Pipe
Arch culverts provide a versatile and economic alternative to the cast-in-place concrete
bridge. With spans available up to 169 inches, and the ability to be installed in single or
multi-line configurations, almost any requirement can be met. Compared to cast-in-place
culverts orbridges, precast Pipe Arch culverts are much quicker to install, usually requiring
no more than 3 to 4 days from start to finish.
