General Project Narrative:This project involves the replacement of Bridge No. 050097 over an unnamed tributary to Shawneehaw Creek on SR 1333 (Shoemaker Rd) in Avery County, NC. The bridge will be replaced with a 1 @ 10’ x 4' cast-in-place, three sided, bottomless culvert. The proposed culvert is approximately 50' in length at a skew of 37° to the proposed roadway and has a slope of 7.0%. The first option considered for replacing the existing bridge was a 36" girder bridge. This option was ruled out because the girders blocked the channel to an extent that the bridge would not have functioned hydraulically. In order for a girder bridge to work the proposed roadway grade would have needed to have been raised significantly which was not possible at this site. With this in mind the proposed bottomless culvert was chosen. Bridge replacement and associated roadway improvements have been designed in a manner to minimize the increase in impervious surface area to the maximum extent possible. A proposed roadway ditch tying to the existing roadway ditch will transport drainage flowing to the project from the North West. The proposed roadway ditch will tie back into the existing roadway ditch prior to flowing past the downstream wing wall of the proposed culvert on the western side of the stream. This section of existing roadway ditch will be protected from erosive forces with class 'B' rip-rap toe protection. The drainage shall empty onto the class 'I' rip-rap stream bank stabilization downstream of the proposed culvert and flow to the unnamed tributary to Shawneehaw Creek. Drainage flowing to the project from the East will be collected in the proposed roadway ditch and be transported south along the proposed roadway until it ties into the existing roadway ditch. The proposed detour allowing for construction of the proposed bottomless culvert will be constructed using temporary shoring where necessary to avoid overly long fill slopes and will have minimal impacts on the surface water drainage on the project. During construction, drainage flowing to the project from the North West will flow alongside the fill slope of the proposed detour before emptying into the UT to Shawneehaw Creek. Drainage flowing to the project from the East will be unaffected by the detour. Typical Cross Section Description: References 170 0.10 Average Daily Traffic (veh/hr/day): ac.
