New Elk Mine Bridge Repair and Replacement Project <br />arcadis.com <br />New Elk Mine Cultural Report_TB_Rev030722 NOT FOR PUBLIC DISCLOSURE 31 <br />Smithsonian <br />Site Number Site Description Management Recommendations <br /> 5LA.14438 <br />Structure: C&W Railroad <br />Concrete Slab Bridge at MP <br />20.72 <br /> <br />Not Individually Eligible <br />Contributing to C&W <br />Restoration and Preservation; the proposed scope of <br />work to be conducted on 5LA.14438 is limited to the <br />removal of ballast from the existing deck, the cleaning of <br />deck drains and bearings, and the application of concrete <br />sealer. Project activities will not remove, replace, or <br />otherwise alter any distinctive or qualifying historic <br />features or characteristics of the NRHP-eligible C&W <br />Railroad, nor will project activities alter the course of the <br />railroad or the height of the railroad grade. Following <br />Project completion, the site will be restored to its original <br />form and intended purpose. <br /> 5LA.14439 <br />Structure: C&W Railroad Box <br />Culvert at MP 21.28 <br /> <br />Not Individually Eligible <br />Contributing to C&W <br />None; while the culvert at MP 21.28 is recommended as <br />a contributing element to the C&W Railroad’s eligibility, no <br />work will be conducted on the culvert, and therefore does <br />not require protection. <br /> 5LA.14440 <br />Structure: C&W Railroad <br />Culvert at MP 24.96 <br /> <br />Not Individually Eligible <br />Non-Contributing to C&W <br />None; no work will be conducted on the culvert at MP <br />24.96; further, the resource is a minor-built feature of the <br />C&W and is recommended not individually eligible for <br />NRHP listing and as a non-contributing element to the <br />C&W Railroad’s eligibility, and therefore does not require <br />protection. <br /> 5LA.14441 <br />Structure: C&W Railroad <br />Culvert at MP 24.98 <br /> <br />Not Individually Eligible <br />Contributing to C&W <br />None; while the culvert at MP 24.98 is recommended as <br />a contributing element to the C&W Railroad’s eligibility, no <br />work will be conducted on the culvert, and therefore does <br />not require protection. <br /> 5LA.14442 <br />Structure: C&W Railroad <br />Culvert at MP 25.86 <br /> <br />Not Individually Eligible <br />Non-Contributing to C&W <br />None; no work will be conducted on the culvert at MP <br />25.86; further, the resource is a minor-built feature of the <br />C&W and is recommended not individually eligible for <br />NRHP listing and as a non-contributing element to the <br />C&W Railroad’s eligibility, and therefore does not require <br />protection. <br /> 5LA.14443 <br />Structure: C&W Railroad <br />Culvert at MP 25.95 <br /> <br />Not Individually Eligible <br />Non-Contributing to C&W <br />None; no work will be conducted on the culvert at MP <br />25.95; further, the resource is a minor-built feature of the <br />C&W and is recommended not individually eligible for <br />NRHP listing and as a non-contributing element to the <br />C&W Railroad’s eligibility, and therefore does not require <br />protection. <br /> 5LA.14444 <br />Structure: C&W Railroad <br />Culvert at MP 13.62 <br /> <br />Not Individually Eligible <br />Non-Contributing to C&W <br />None; because the box culvert at MP 13.62 is a minor- <br />built element of the C&W Railroad, it is not considered a <br />contributing feature of the C&W Railroad and does not <br />require protection. The culvert at MP 13.62 will be <br />replaced with a smooth steel pipe culvert protected by <br />riprap. The Project will not alter the C&W railroad grade’s <br />route, height, or any other qualifying characteristics of the <br />railroad’s NRHP eligibility.
