Typical Cross Section Description:
The proposed typical section consists of two 10' wide travel lanes and 3' shoulder berm
gutter on both sides and paved shoulder on the highside of superelevation.
The existing 2-lane paved approaches are approximately 9' each(18' total paved
width) with a total clear roadway approximate width of 17.25' at the existing bridge.
Annual Avg Daily Traffic (veh/hr/day):
Design/Future: 580 Year: 2032

General Project Narrative:
(Description of Minimization of Water
Quality Impacts)
The purpose of the proposed project is to replace Bridge No. 560166 on SR1533 (Hamburg Rd) over Terry Fork in Madison County. The existing bridge is a single span 2770"
timber deck on I -beams rated in fair condition on the latest structure safety report. The replacement structure will be 2 @ 9' x 6' RCBC. The proposed culverts will have a skew
of approximately 45 degrees. The roadway alignment will be adjusted slightly and the grade for the new structure will be raised slightly to accommodate proper vertical and
horizontal curve design standards. The majority of the roadway storm water run-off will sheet flow off of the roadway across vegetated shoulders prior to entering the stream. A
berm ditch will collect stormwater runoff from running down a proposed cut slope and discharge to a proposed storm drain system. Two new TB 2G1 and one MCF will collect
water from the shoulder berm gutter and dischage it to the adjacent stream.

Avoidance and Minimization Efforts:
(Bridge to Culvert)
The 9' wide reinforced box culverts were selected to reduce impacts to the stream bed downstream of the existing structure. One culvert will
maintain the approximate natural channel width of 9' and will utilize 1' sills, while the additional 9' wide culvert will utilize 1.5' sills for high flow
water surface elevations. Both culverts will utilize excavated, existing bed material.
Stream Slope
Fish and/or Aquatic
Life Passage
Existing Average Stream Slope

Existing Low Flow Channel Dimensions
in the Stream:
Stream width varies, but it has an
approximately 10' wide low flow area,
approximately 1' deep.
Proposed Culvert Slope (%):

Culvert Burial
Proposed Culvert Burial Depth (ft):
1.0'
Existing Streambed Material:
Cobble and gravel with coarse sand.
Proposed Low Flow Dimensions
Through the Culvert:
Approximately 10' wide low flow area,
approximately 1' deep.
Proposed Sills/Baffles:
1.0' sills across main channel, 1.5' sills across high -
flow culvert.
Existing Low Flow Velocities in the
Stream (ft/s):
0.8
Proposed ow ow Velocities Through
the Culvert (ft/s):
2.1
Alternating Low Flow Sills/Baffles:
1.0' sills across main channel, 1.5' sills across
high -flow culvert.
Culvert/Stream Alignment
Stream Patterns Upstream and
Downstream of the Culvert that Could
Affect Fish Passage and Bank Stability:
Mostly uniform stream geometry with approximate 10' wide stream bed. Existing banks appear stable. Existing 36" driveway culvert upstream of
proposed structure may impead aquatic movements.
Bed Forms Impacted by Culvert (riffles,
pools, glides, etc.):
Reinforced concrete box culverts to match exsitng stream geometry and minimize impacts.
Low Flow Floodplain Bench Required?

No
Bends at Inlet/Outlet?
(describe culvert alignment with stream)
No
Stream Realignment Necessary? (provide
justification)
No
Bank Stabilization:
Wing walls are planned to maintain bank stabilizations along the roadway. Minor rip -rap bank stabilizations is planned approximately 10'
upstream, and 10' downstream of the proposed culvert to protect araded slopes.
Outlet Velocities
Natural Stream Channel 2-yr Velocity (ft/s):
6.1
Natural Stream Channel 10-yr Velocity (ft/s):
8.4
Proposed Culvert 2-yr Outlet Velocity (ft/s):

Proposed Culvert 10-yr Outlet Velocity (ft/s):
10.8
Roadway Geometric Considerations
Evaluate/Describe Roadway Geometric Constraints:
Roadway constraints are primarily created by the proximity of the adjacent stream which flow approximately parallel to the roadway.
