What are key connection changes in the Montlake area?
The West Approach Bridge North (WABN) project will enhance connections in the Montlake area.
Below are several engineering plans that provide additional detail on the Montlake section of the WABN project.
Existing structures that will be removed
High-level overview of new structures compared to existing structures that will be reconfigured
As shown above, westbound traffic would travel on new structures, while eastbound traffic would use the existing roadway. The 24th Avenue East bridge would be reconfigured for southbound traffic only, and would be used as a westbound off-ramp.
How will the West Approach Bridge North connect with other planned SR 520 projects?
The construction schedule for WABN is carefully timed to coincide with activities for both the new floating bridge and the west connection bridge:
Step 1 - Floating Bridge: Work on the new floating bridge (yellow) is already under way on Lake Washington.
Step 2 - West Connection Bridge: Construction is complete on a new structure (orange) that will connect the new floating bridge to the existing west approach bridge, scheduled for spring 2016.
Step 3 - West Approach Bridge North: When the new West Approach Bridge North (blue) opens to traffic, scheduled for summer 2017, westbound traffic will travel on the new structure while eastbound traffic will travel on the existing west approach and the West Connection Bridge.
