General Project Narrative:
This project replaces existing BR #000125, 1 @17' -811, 1 @17' -0", 1 @17' -8" spans timber floor, 26' -0" wide out to out. The proposed bridge will be a single span @ 85' -0", 33"
Box Beam, Spill Thru Abutments, 30' wide out to out. Deck drains will not be required. Runoff from the bridge will be captured on the low end of the bridge and discharged
into a rip rap pad into an existing swale at the base of the fill slope outside of the buffer. The discharge velocity from the rip rap pad is non - erosive at 0.6 fps. There is a slight
increase in the impervious area of the project, however there is no significant increase in the discharge from the roadway runoff. The fill in the wetlands was minimized by
steepening the slopes to 2:1.
