  • SR 3 and SR 16 capacity improvements by peak-use shoulder lanes and widening
  • SR 304/Naval Base Kitsap-Bremerton area improvements at Farragut Avenue and Charleston Beach Road
  • SR 3/SR 16 interchange access control, intersection improvements, and grade separation
  • Tremont Street and Sedgwick Road interchange capacity improvements at key intersections
  • SR 302 and Borgen Boulevard Interchange capacity, operational, and queue storage improvements
  • Olympic Drive, Wollochet Drive, and Hunt Street crossing operational and capacity improvements

Corridor-wide recommendations include:
