A system and method are provided for increasing the width of an existing roadway. The system incorporates a reverse-oriented retaining wall and soil nail supports. The retaining wall is formed by a first set of soil nails, wire mesh material, and one or more geotextile material layers. An alternate embodiment forms the retaining wall with a plurality of concrete blocks stacked and spaced to form a block wall. The blocks are mounted over the first set of nails. Backfill material fills a gap between the existing sloping surface and the retaining wall. A second set of soil nails can be provided for additional subsurface support. An upper surface of the backfill material can be paved to form the extended roadway width.

1. 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 a first plurality of soil nails having first ends in the sloping surface, said first plurality of nails having second exposed ends extending away from the sloping surface;placing a wire mesh material over the first plurality of soil nails and securing the wire mesh material to the first plurality of soil nails;embedding a second plurality of soil nails having first ends embedded in the sloping surface and having second exposed ends extending away from the sloping surface;forming an exterior wall adjacent the first plurality of soil nails wherein said exterior wall extends at a reverse orientation, and a gap being located between the exterior wall and the adjacent side of the roadbed;filling the gap with backfill material; andplacing a road surface over the backfill material thereby creating a lateral roadway extension of the road. 2. A method, as claimed in claim 1, further including: securing a plurality of shear resisting dowels each having a first end secured in the sloping surface, and having a second end extending into the backfill material. 3. A method, as claimed in claim 1, further including: applying a treatment to exposed surfaces of the first plurality of soil nails and, wire mesh material, the surface treatment including at least one of concrete, plaster, stain, and paint. 4. A method, as claimed in claim 1, further including: placing a longitudinal waler adjacent to the exposed ends of the first and second plurality of soil nails and secured to the exposed ends of the first plurality of soil nails. 5. A method, as claimed in claim 1, wherein: at least one of the first and second plurality of soil nails includes two sections interconnected by a coupler. 6. A method, as claimed in claim 1, wherein: at least one of the first and second plurality of soil nails includes a tubular outer member, an inner member, and a centering feature disposed in the outer member for concentrically spacing the inner member within the outer tubular member. 7. A method, as claimed in claim 1, wherein: the first plurality of soil nails extending at a first reverse angle as measured from a vertical line;the second plurality of soil nails extending at a second angle and extending more horizontally as compared to the first plurality of soil nails. 8. A method, as claimed in claim 7, wherein: the first plurality of soil nails extend at the first reverse angle that substantially defines the shape of an exterior exposed surface of the retaining wall. 9. A method, as claimed in claim 1, further including: securing at least one bearing plate to a soil nail of the first or second plurality of soil nails. 10. A system, as claimed in claim 1, further including: mounting a roadway barrier to an upper surface of the roadway extension. 11. A method, as claimed in claim 1, further including: placing a laterally extending waler extending substantially perpendicular to the first plurality of soil nails. 12. A method, as claimed in claim 1, further including: placing a longitudinal waler adjacent to the exposed ends of the first and second plurality of soil nails and secured to the exposed ends of the first plurality of soil nails; andplacing at least one lateral waler extending laterally as compared to the first plurality of soil nails. 13. A method, as claimed in claim 1, further including: placing a geotextile material over the wire mesh material prior to said filling step, and securing the geotextile material to the wire mesh material. 14. A method, as claimed in claim 1, wherein: forming said exterior wall includes placing a plurality of blocks over or adjacent to the first plurality of soil nails, and stacked on one another forming a block wall. 15. A method, as claimed in claim 1, wherein: said backfill material filling said gap forms a generally V-shape. 16. A method, as claimed in claim 1, further including: placing at least one length of rebar extending substantially parallel to the roadway adjacent to said exposed ends of the first and second plurality of soil nails, and secured to at least one of the exposed ends of the first and second soil nails. 17. A method, as claimed in claim 1, further including: embedding a plurality of shear resisting dowels each having a first end secured in the sloping surface, and having a second end extending into the backfill material. 18. A method, as claimed in claim 1, further including: connecting a plurality of bearing plates to corresponding exposed ends of said second set of soil nails. 19. 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; andwherein 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. 20. A method, as claimed in claim 19, wherein: said at least one length of rebar extends substantially parallel to the roadway adjacent to the exposed ends of the first and second plurality of soil nails. 21. 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; andfilling 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. 22. A method, as claimed in claim 21, further including: installing a second plurality of soil nails in the sloping surface adjacent the first plurality of soil nails, wherein the second plurality of soil nails extend at a more horizontal angle as compared to the reverse angle of the first plurality of soil nails.
