Typical Cross Section Description: Two - 11' wide paved travel lanes with variable shoulders and grassed side slopes Two - 11' wide paved travel lanes with 6' grassed shoulders. Bridge is two - 11' lanes ranging from about 4(H):1(V) to 2(H):1(V). with 1' shoulders. Annual Avg Daily Traffic (veh/hr/day): Design/Future: Year: 2025 Existin : 2250 Year: 2011 General Project Narrative: Project involves replacement of Bridge No. 40 on SR 1116 (Bishop Ave) over Hickory Creek in Guilford County, north of Julian, NC. Bridge is within Randleman Watershed with (Description of Minimization of Water Buffer Rules. Approach work will consist of raising the existing roadway grade and providing grassed shoulders. Existing structure is a 2 span bridge (2 @ 17'-8" long - 23' wide Quality Impacts) Timber Deck on I-Beams w/ timber vertical abutments) and will be replaced with a 2@ 14' x 12' RCBC. Best Mgmt Practices: -Promotion of sheet flow and infiltration with grassed shoulders. -Tying drainage to existing ditches.
