Abstract: A modular portable wheel chair ramp comprising a plurality of mechanically interconnected modular ramp sections. Ramp sections are supported by adjustable post assemblies on ramp section sides. A rail panel comprising upper and lower rails extend between said outer post on one end and a second post matching in complement the outer post on an opposite end wherein said second post of a first rail panel removably connects to an outer post of an adjacent rail panel therein connecting said rail panels together. Slats connecting between upper and lower rails form a rail panel. An inner rail is also secured between the posts, interlocking with an extended lug on an inner rail section end fitting into a matching hole in an adjacent inner rail section end to make a continuous inner section rail.
