The bridge replacement on NC 11/111 conveys Burn Coat Creek from North to South and ultimately drains into the Northeast Cape Fear River.
The existing bridge, overall length OAL = 65' and width 30’ will be replaced with a bridge having an OAL = 105’ and width = 30’. The new bridge is longer than the existing bridge
to accommodate the spatial difference between the previous bridge location to the new location.The proposed bridge and roadway improvements minimized the existing
overtopping condition and maintain a minimal transition between existing and new roadway.
Runoff from the bridge is captured on the low side of the bridge in shoulder berm gutter and traffic bearing 1 Gl's on either side of the road. The 18" pipe systems are designed
to outfall (with rip rap outlet protection) outside of buffer zones 1 and 2.
Burn Coat Creek is a FEMA stream that is shown on Flood Insurance Rate Map (FIRM) panel 370254-2563-K, dated 06/20/2018. A hydraulic analysis on Burn Coat Creek was
performed to assess the potential flood level increases associated with this project. Based on this analysis, the proposed bridge replacement project was shown to have a
maximum base flood level increase of 0.1' after the bridge and a maximum decrease in base flood elevation of 0.1' before the bridge. This project qualifies for an MOA Type 2d.
Additionally, rock platting has been used on slopes of 1.5:1 to prevent increased impacts to the existing wetlands.
