System and method for increasing roadway width incorporating a reverse oriented retaining wall and soil nail supports

A method of constructing a retaining wall system constructed on a sloping surface having a sloping grade extending away from an adjacent side of a roadbed of a road, the method comprising:

• embedding first ends of a first plurality of soil nails in the sloping surface, and the first plurality of soil nails having second exposed ends extending away from the sloping surface;
• placing a plurality of blocks over the first plurality of soil nails and stacked on one another forming a block wall;
• embedding first ends of a second plurality of soil nails in the sloping surface, and the second plurality of soil nails having second exposed ends extending away from the sloping surface;
• securing at least one length of rebar to at least one of the exposed ends of the first and second soil nails;
• placing backfill material in a gap between the sloping surface and the block wall, and when viewing the retaining wall from a vertical cross-section, the backfill material having a generally V-shape;
• and
• wherein the backfill material has one side thereof abutting a lateral edge of the roadbed and a road surface placed over the backfill material thereby creating a lateral roadway extension of the road.

A method of constructing a retaining wall system constructed on a sloping surface having a sloping grade extending away from an adjacent side of a roadbed of a road, the method comprising:

• installing a first plurality of soil nails spaced apart from a lateral side of the road, the first plurality of soil nails extending at a reverse angle, and the first plurality of soils nails secured in the sloping surface adjacent to the road;
• providing a plurality of blocks and mounting the blocks to extend adjacent with or over the first plurality of soil nails thereby forming a block wall aligned at said reverse angle;
• and
• filling a gap between the sloping surface and an exterior wall formed by the block wall, the backfill material having an upper surface that is near an elevation as the road, and a width of the upper surface defining a lateral roadway extension of the road.
