The existing structure is a three span bridge (1 @ 41'; 1@ 40'; 1 (Description of Minimization of Water @ 41' - 122' total length) with steel plank deck on I-beams. The proposed structure will be a three span bridge (1 @ 30'; 1@ 70'; 1@ 30' - 130' total length) with 24" Cored Quality Impacts) Slabs. The existing bridge is an open deck with direct discharge into the creek across entire reach of structure. The proposed bridge will have no deck drains and drainage will be conveyed into an that will outlet through vegetation prior to entering the buffer. Existing ditches in the NE, NW and SW quads are presently unstable and eroded. Propose to armor these existing ditches with rip rap within R/W to stabilize. There are 2 proposed outfalls on the project in the SW and SE quads that flow through vegetation. In the SW quad road drainage ties to a modified concrete flume. In the SE quad road drainage ties to an 2GI inlet pipe system. Drainage area to 2GI inlet structure = 0.13 ac Q2=0.5cfs; Q10=0.7cfs V2=1.4fUs; V10=1.5ft/s Drainage area to Modified Concrete Flume=0.03 ac.
