Replacement of Bridge No. 400456 on SR 2136 (Fleming Road) in Guilford County. The existing bridge, overall length (OAL) = 75' and width = 25', will be replaced with a
bridge having an OAL = 85' and width of 42'. The new bridge is wider than the existing bridge to provide the required shoulders necessary for roadway and drainage. The
roadway is being widened to provide the minimum lanes for safe travel. A detour bridge, overall length 65' and width 28.5', will be constructed east of the existing/proposed
bridge. This bridge will be removed and area allowed to re-vegetate once the primary bridge has been replaced. Roadside ditches that were affected due to the detour and
mainline fill slopes were replaced in kind. No new roadside ditches were introduced as part of this project.
Wetlands on the left (west) side of the roadway should only have a minimal impact. No fill or excavation is anticipated in these wetlands. There are small areas of the wetlands
that are located within the proposed PDE. Mechanized clearing has been shown in these areas as a worst case scenario, but ultimately impacts are not anticipated. Wetlands
on the right (east) side of the roadway will be impacted due to the detour. The detour roadway embankment will be graded back down to natural ground elevation after the
proposed bridge is constructed. This will provide an environment for the wetlands to potentially re-establish over time.
Rip rap is placed on the bridge sloping abutments to act as slope stabilization and prevent erosion. Runoff from the bridge is captured on the low side of the bridge in shoulder
berm gutter and traffic bearing 2GI's on either side of the road in the roadway sag. The system is designed to outfall outside of buffer zone 2 in the area of an existing wetland
that will be disturbed by the detour. Once this wetland is allowed to re-establish it will provide treatment for the system outfall.
The roadside ditch on the begin bridge right side that is being replaced due to the detour impacts is being replaced as a grass swale. This ditch will treat the additional
impervious area from the paved shoulder on the begin bridge right side. The velocity of the swale entering the wetland is less than 2.0 fps.

* Total Permanent Channel Impacts along the centerline of Brush Creek is 37 linear feet.
** Total Temporary Channel Impacts along the centerline of Brush Creek is 72 linear feet.
*** Causeway #1 blocks more than 50% of the channel. Therefore, 1 @ 30" temporary pipe to be installed with causeway to help convey
the average daily flow.
**** Causeways #1 and #2 should not be in place at the same time. There is an overlap in impact area between the causeways. However,
the Total Temporary Surface Water Impacts remain 0.04 acres due to the minimal overlap area.
