A series of modules serve to provide a base for walkway members to be assembled into a walkway. Modules provide for support and orientation of walkway members and the ability to produce complex walkways with segments at varying orientations. In a preferred embodiment, a base mat is sized to engage walkway members. Using a combination of a number of base mats and walkway members, segments of walkway of any desired size can be readily assembled. Reflective and non-slip surfaces can be applied to increase safety when in use.
