Annual Avg Daily Traffic (veh/hr/day): Design/Future: Year: Existin : Year: General Project Narrative: The project consists of replacement of Bridge 126 on SR 1526 (Gray Rd) over Lick Creek and associated roadway work. The existing structure is a three span (1 @ 25', 2@ (Description of Minimization of Water 26') timber deck on i-beams bridge. The proposed structure will be a 4-sided 34'-11"x10'-4" aluminum box culvert. All project drainage will tie to existing, established outfalls. Quality Impacts) Outfalls within project limits are stable.

Sills and BafFles with a low flow notch are proposed to mimic the low flow (Bridge to Culvert) channel dimension along the stream. Low flow velocities through the culvert are consistent with the stream natural channel low flow velocities.
