ArchLok is a complete arch bridge system consisting of precast concrete segments which lock together to form tunnels or bridges.

The ArchLok system is comprised of 2 or more reinforced precast concrete units in the shape of curved segments, constructed separately and then leaned against each other to form an arch. The arch rests on cast footings with keyways on which the segments are placed. When in position a cast crown beam and grout keyway are added to the seam where the segments meet to add support.
