The SR 303 Manette Bridge Replacement Project was built in the Naval Shipyard town of Bremerton, Wash. The project team took part in a collaborative, interdisciplinary design approach that involved all stakeholders and resulted in a new modern bridge that preserves and enhances the scenic and historic community. This project replaced an 80-year- old bridge that was important to the city and neighborhoods in terms of transportation of goods and services and civic pride. Some of the greater challenges that needed to be addressed by the project team included the following: • The existing bridge was to remain open during construction of the new bridge. • T h e n e w b r i d g e n e e d e d t o b e a rc h i t e c t u r a l l y i n t e re s t i n g and unique to satisfy the local community, yet economical to fit within the budget. • The bridge foundation had to resist high seismic forces coupled with swift currents and large scour potential. • T h e n e w b r i d g e w a s t o b e constructed within 3 ft of the existing bridge to facilitate tie-in with existing roads. • The bridge is not part of the state highway system, but state law had dictated that the state was responsible for the bridge's replacement.
