Certification for proposed replacement of Alleghany bridge 122,Alleghany County,North Carolina,Division 11,WBS
11B.200311—State Funded
Dear Lori and Dave,
NCDOT proposes to replace Alleghany bridge #122 in kind with concrete abutments and 30'xl4" steel beams and
wooden deck and wooden rails. The existing bridge is structurally deficient and poses a safety hazard. All work will be
completed within the existing footprint of the current bridge and roadway, so no new grading/clearing/tree cutting
required. The visible portions of the new bridge should be similar in appearance to the existing bridge,with wooden deck,
wooden handrails, and ABC/gravel driving surface. The two main differences between the existing bridge and the new
bridge will be the replacement of the wooden abutments with concrete abutments, and the new bridge will be 10' longer
(same width as existing bridge). This longer length will allow us to build the new abutments further back from the stream
edge (the existing bridge is right on the stream edge and subject to scour from the stream). The use of concrete abutments
will lengthen the life of the new bridge and further reduce any possible issues from flood events. The only proposed
impacts will be 30' of temporary dewatering,to allow us to remove the old abutments in the dry.
Protected Species/Section 7
As of 2-1-23,USFWS IPaC lists the following species(no critical habitats in the area):
Gray Bat,Northern Long-eared Bat(NLEB), and Tricolored Bat(the latter is proposed,but not currently listed): The
existing bridge was surveyed by NCDOT staff during the summer of 2022. The bridge is only a few feet above the water,
laden with creosote and does not provide crevices suitable for roosting. No bats or signs of bats were observed.No caves
or mines are in the area,no tree clearing,no permanent or temporary use of artificial lighting will occur, and no blasting
or percussion activities will occur. As a result,NCDOT would like to propose a biological conclusion of"No Effect".
Bog Turtle: The project will not affect bog turtles, as there will be no wetland impacts,
If you have any questions or need additional information,please contact me at(828) 386-7202.
Sincerely,
