General Project Narrative: The existing bridge a is an 18'-2" single span timber deck on timber joists bridge with yount masonry abutments carrying Dickie Little Road over North Fork Jones Creek.The
(Description of Minimization of Water existing bridge is being replaced with 30' wide 1@55' span cored slab bridge with 2.5' end bent caps and sloping abutments. The existing concrete abutments shall be cut off at
Quality Impacts) elevation 433.5 ft. The existing bridge structure will be removed. As the proposed design interferes with the existing drainage, ditches were proposed on both sides of the begin
and end bridge. On the end side of the bridge, a traffic bearing grated drop inlet with double frame and grates (2G1) was placed on the right side of the roadway in the shoulder
berm gutter to pick up runoff from the bridge. Class-II rip rap abutment protection on both banks of the stream is also proposed to prevent future erosion and stream migration.
Deck drains are not needed. No dissipator pads were used because the Class-II rip rap will prevent erosion and dissipate flow.
