Abstract:This report summarizes the recommendations of participants attending a workshop on March 16-17, 1999 in Portland Oregon, to consider for preservation or reconstruction of Interstate 5 (I-5) in Portland. Participants from state Department of Transportation in Georgia, Washington, Michigan and Oregon joined Federal Highway Administration, City of Portland and industry personnel to discuss this stretch of I-5, which is nearing the end of its 30-year design life.
The participants reviewed the project considerations and constraints, discussed similar project experiences, and brainstormed options for preservation/reconstruction and traffic management. Seven options were compared for five factors: 1) pavement related costs, 2) structure raising costs, 3) traffic control/detour costs, 4) other costs, and 5) user costs. Two promising options were analyzed in detail: Full reconstruction with concrete (full closure and partial closure) and Asphalt concrete overlay. A life-cycle cost analysis was done for both options.
The report includes project background, examples of similar projects from Georgia and Michigan, the list of brainstormed options, details of options discussed in more depth, and identified issues relating to contracting options.
