Construction of the west connection bridge is planned to begin as early as spring 2013.
Construction timing with other SR 520 projects
The construction schedule for the west connection bridge is carefully timed to coincide with activities for both the new floating bridge, currently under construction, and the future west approach bridge north that connects the floating bridge to the Montlake area.
The north half of the new west approach bridge is fully funded for construction, planned to begin in summer 2014; the south half is among $1.4 billion in unfunded SR 520 corridor projects.
Step 1 - Floating bridge: Work on the new floating bridge is already under way on Lake Washington.

Step 2 - West connection bridge: Later in 2013, we'll begin building a structure that will connect the new floating bridge to the existing west approach bridge.

Step 3 - West approach bridge north: Starting in summer 2014, we will start work on the West Approach Bridge North (WABN). When WABN is complete, westbound traffic will travel on the new structure while eastbound traffic will travel on the existing west approach and the west connection bridge.
