Typical Cross Section Description: Two 11' paved travel lanes with 2' paved shoulders and 2' grassed shoulders (5' with guardrail). Two 11' paved travel lanes with 3'-10' grassed shoulders. Annual Avg Daily Traffic (veh/hr/day): Design/Future: 300 Year: 2016 Existing: 300 Year: 2016 General Project Narrative: (Description of Minimization of Water Quality Impacts) Replacement of Bridge No. 730005 on SR 1777 (Blackjack-Grimesland Rd.) over Chicod Creek in Pitt County, NC. The proposed 135' long by 33' wide three -span bridge would replace the existing 91' long by 33' wide two span bridge. The proposed grade will be about 0.5' above existing ground within the vicinity of the bridge and roughly matching existing ground outside of the bridge. Bridge No. 730005 is within the Tar -Pamlico River Drainage Basin and shall adhere to the Tar -Pamlico Buffer Rules. The proposed bridge will have no direct discharge into Chicod Creek. Stormwater runoff from the the proposed bridge is to flow to two traffic bearing grated inlets at each side of the bridge where it will be diffused with a riprap pad at the proposed pipe outlet. All proposed runoff is discharged as far away from the stream and at the lowest velocities as practicable. The proposed deck runoff will outlet outside of buffers.
