S. Moore & F.J. Miller, Engineers / H. L. Maddocks, Builder Property Owner: St. Joseph County (Bridge #211) Landmark or District Designation: Local Landmark #9104-2000 Rating: Outstanding DESCRIPTION OF STRUCTURE/SITE: The Angela Bridge is a three Arch Melan style bridge constructed of reinforced concrete, having two central pillars with corbelled string coursecones at pillar bases and plain spandrels. The bridge construction method relied on bands of several metal arch rings aligned evenly with the protection of a concrete shell. Rough faced cut stone comprises the facing of the structure. ALTERATIONS: COA #2001-0815 allowed for repointing of masonry, replacing pavement, sidewall, and spandrel walls, outside rails, vertical posts above floor beams, the replacement of cross beams as needed, the removal of non -historic aluminum rail, recoating of masonry, COA #2003-0616 allowed for the replacement of the original, deteriorated approach railings with railings of identical shape size, dimensions and design as the existing except that for NHTSA standards rails, piers, and the oval openings were modified. Openings in both the approach and the guard rail were elongated. Conduit for the future installation of light poles was installed, as well. COA •#2003-0916-1 allowed for the construction of the trailhead for the Coal Line trail. COA #2010-1206C allowed for the installation of eight Leesburg light poles with Main Street -A luminaires, as well as improvements to the western bridge approach (including the roundabout). APPLICATION ITEMS: "This project includes the installation of lights on the Angela Bridge of the same type currently existing on Angela Blvd. to the west of the bridge. This project will add six (6) lights, to the locations where existing conduit is located, and will require no modifications to the bridge or railing." DESCRIPTION OF PROPOSED PROJECT: Applicant seeks a Certificate of Appropriateness for improvements on the structure including: Installation of six (6) SternbergLighting model #4510FP4 poles (measuring 10' tall with a 10'/z" diameter base) along the bridge. a. The lights will be distributed as follows: i. One set at the western edge of the bridge, over pier 1, ii. One set near the midpoint of the bridge, between pier 2 and 3, iii. One set at the eastern edge of the bridge, over pier 4. b. "Lights shall be attached using 18" straight bolts with 14" of the thread embedded into the top of the bridge rail and 4" of the thread exposed. Bolts locations shall be drilled and epoxy, then hammered in. The Contractor shall field verify, and drill locations shall be approved by the city's representative." c. Two extra light poles will be supplied to the city to be used as spares. COA #2010-1206C allowed for the installation of eight (8) Leesburg 12' straight fluted shafts with Main Street -A luminaires (models #MS805-B or #MS805-B-0) atop. The existing bridge superstructure/railing is not sufficiently • wide enough to support the Leesburg 12' base, which is approximately 20" in diameter. Narrower bases are therefore required, necessitating the change in light pole. The Luminaire is of the same style, but is now the LED light model. The existing conduit (installed in 2003) was configured for the installation of six lights.
