Eklutna River Bridge Rehabilitation: Preserving the Historic Old Glenn Highway Crossing
The Municipality of Anchorage Department of Project Management and Engineering chose to rehabilitate the Eklutna River Bridge, a historic three-span structure comprised of two multiple I-beam approaches and a unique arched deck truss main span. The geometry of the main span is complicated with three truss lines, canted exterior trusses, and an arched bottom chord. The bridge is located north of Anchorage, Alaska, in an area of high seismicity. This paper discusses the finite element modeling and structural analysis performed, and presents the main rehabilitation tasks undertaken. The rehabilitation includes repairing the existing deterioration, widening the deck with new bridge rail for combination vehicle and bicycle traffic, increasing the live load capacity to HS20, and upgrading the structure for seismic loads. All rehabilitation was designed while preserving this historic structure for its intrinsic value.
