Existing roadways consists of two 11' lanes, with 3' unpaved shoulders. Existing
condition is at a superelevtion (approx. 0.040) at the bridge approach and throughout

The proposed typical section on either side of the bridge will be superelevated with a
cross slope of 0.040, after the bridge section the typical section transition back to normal
crown. Lanes consist of two 10' lanes with 3' paved shoulder and 3:1 or flatter side
slopes to existing ground with the exception around the bridge opening where side
slopes transition to 2:1 and 1.5:1 around bridge opening

State project 48202.2.1 will consist of replacing the structurally deficient NCDOT bridge #770108 on SR 2269 over Indian Swamp. The proposed replacement structure is a 2-
span (1@50’, 1@35') 21” PCCS with 2.5’ caps with an out-to-out deck width of 33’ which will replace the existing 2-span (1@30-7”, 1@30’-9”). Roadway fill slopes will vary
between 3:1 and 4:1, with the exception of the brige opening which will transition to 1.5:1, and will all be grassy to encourage a diffuse flow pattern and passive stormwater
treatment. Stormwater runoff from the bridge and approach slabs will be collected by traffic bearing grated inlets where it will discharge to roadside swales with rip rap dissipator
pads at the pipe outlets. There are no wetlands present for this project.
