Brown Bridge DemolitionContractor: Concrete Enterprises | |||||||||||||||||||||||||||||
McGee Engineering developed a bridge demolition plan for the Brown Bridge which was being demolished near Roseburg, Oregon. The existing bridge was a 3-span (110' - 140' - 100'), 3-cell, mild reinforced cast-in-place concrete box beam bridge with four 65' long prestressed concrete multi-beam approach spans. Schedule constraints presented unique challenges on this project; much of the demolition needed to occur before the in-water work window, requiring demolition equipment to operate on top of the bridge and containment systems to be supported without in-water impact. Low quality concrete encountered during demolition introduced additional complexity and required temporary shoring before demolition could be completed.
