Mr. Matthew Clark, Chairperson HWY-DS 2.21186 October 3, 2025 Page 2 address deficiencies identified during the latest bridge inspection conducted by the HDOT. The proposed project activities will include the following: • Replacing the heavily-corroded deteriorated superstructure, such as the steel truss members, bearings, gusset plates, rivets, etc. • Repairing spalling in the concrete deck and railings. • Cleaning and painting the steel members following replacement. • Installing scour protection at the pier foundation, which may involve in-water work. • Conducting soil mitigation if lead-impacted soils are found beneath the bridge. • Removal of the temporary AcrowTM structure that supports the bridge. Consultations Entitled consulting parties during the Section 106 process includes the Advisory Council of Historic Preservation, SHPO, NHO, and if applicable, local governments and applicants for federal assistance, permits, licenses and other approvals. NHO and/or Hawaiian Descendents NHO and Native Hawaiian descendants with ancestral, lineal, or cultural ties to, cultural and historical property knowledge of and/or concerns for, and cultural or religious attachment to the proposed Area of Potential Effects (APE) are asked to provide a response to this letter within 30 days of notification. Other Individuals and Organizations Individuals and organizations with legal, economic, or historic preservation interest are requested to respond within 30 days of notification, demonstrate interest in the proposed undertaking, and provide intent to participate in the Section 106 process. Your participation is subject to FHWA approval. APE We would like to invite you to comment on the proposed APE. See Attachment 1. The APE is approximately 7 acres located mostly within Hawaii Belt Road and is designated for working areas, construction staging, and material stockpiling. Most of the APE is located within the Hawaii Belt Road ROW (2-9-003:999 and 2-8-015:999). However, one parcel mauka of the highway ROW (2-8-015:015)includes Kolekole Gulch Park and will be used to access the foundations of the bridge and for staging. The land in Kolekole Gulch Park is owned by the state but is managed by the County of Hawaii through its park system, as mandated by an executive order. Vegetation clearing within the APE may be necessary to provide access to bridge foundations and stage equipment and materials.
