Glenn Highway and Muldoon Road Interchange Improvements
Start Date: 2016
End Date: November 2018
Hamilton is working with with Neeser Construction to provide the structural work on this project that replaces the existing Muldoon Road Interchange on the Glenn Highway near Anchorage. This interchange is a major gateway to Anchorage at its northern most junction.
The new Diverging Diamond Interchange will replace the existing cloverleaf. The bridge work includes parallel two-span 222-foot-long bridges founded on driven H-pile at the abutments and 36-inch steel pipe pile at the bents in the median. The superstructure consists of 54-inch Deck Bulb-T girders with an asphalt overlay and waterproofing membrane. Additional work includes ornamental pedestrian bridge railing, cast-in-place concrete coping, and barrier rail for the MSE walls.
