This Design-Build project included design of a new concrete bridge for Kahoma Stream crossing and a single span grade separation structure at Lahainaluna Road.
During the construction phase of this project, archaeological data recovery work encountered an archaeological site (inadvertent find) within the highway corridor. The following regulatory requirements were triggered: 1) Section 4(f) of the U.S. DOT Act requiring consideration of alternatives that avoid use of resources, and identifying other feasible and prudent alternatives; and 2) Section 106 consultation under the National Historic Preservation Act with interested parties to help assess project effects. Additional work tasks included addressing Federal requirements including Section 7 of the ESA, and COE jurisdictional determination and permit. Other permits included State 401 water quality certification, stream channel alteration permit, and NPDES permits.
Unforeseen circumstances were successfully resolved through effective coordination with federal, state and county agencies, community organizations, and other stakeholders.
