The effort to replace the southbound Sullivan Road Bridge across the Spokane River (the westernmost of two bridges that cross the river at that location) began when the October 2009 annual bridge inspection rated its condition as Structurally Deficient. Built in 1951, the aging bridge is a critical transportation link, carrying about 25,000 vehicles across the river and to I-90 each day, including heavily loaded commercial vehicles.
Almost immediately, the City began planning and seeking funding assistance for replacement. Reluctantly, the City posted temporary weight restrictions in June of 2011 to help prolong the life of the bridge. Shortly afterward, the City Council approved funding for temporary repairs so the weight restrictions could be lifted and use of the bridge by heavily loaded vehicles could resume until it can be replaced.
While the bridge is not currently at risk of failure, annual inspections show signs of continued deterioration. The deterioration is typical in bridges of this age, and includes cracking in the girders as well as deterioration of the driving surface. De-icing agents used over the years have also resulted in high chloride content in the bridge's concrete, which can contribute to further deterioration.
