Abstract
Embodiments of the present invention provide a modular, portable, and adjustable wheelchair ramp that provides advantages and benefits over current wheelchair ramps. The ramp may be sold in a kit with individual elements, but it is also designed to provide a frame substructure that can be used with conventional decking materials, railings, and handrails.
