- Priority for transit at intersections.
- Increased transit service.
- Bus rapid transit.
- Reversible transit lane.
- Dedicated northbound transit lane.
- Operating with general traffic.
- Separated pedestrian and bicycle facilities.
- Turn lanes for improved access at intersections.
- Left turn restrictions at intersections.
- Extended HOV lanes.

Other safety and mobility consideration:
- Overpass at SR 305/Bond Road.

- Crash barriers on shoulders.
Why not widen the agate pass bridge?
In 2018 WSDOT conducted a Type, Size and Location (TSL) study to evaluate alternatives to replace the Agate Pass Bridge. The study evaluated three options with total bridge replacements. Two options provided three travel lanes with one or two 15’ barrier separated paths and one provided four travel lanes with two 15’ barrier separated paths. Preliminary construction costs for these options, in 2017 dollars, ranged from $95 million to $127 million. The Agate Pass Bridge replacement is not part of the current SR 305 project, and funding has not been identified for bridge replacement. WSDOT will continue to maintain the bridge to keep it in good working order including annual bridge cleaning and a major painting project that will begin in spring 2019.
What options were not considered and why?
Several options were removed based on recommendations in previous studies:
- Light rail: previous study showed expected ridership within the 20–year planning timeframe would be too low.
- Monorail: not appropriate with suburban/rural nature of corridor, and very low–cost effectiveness.
- Automated fixed guideway: not a tested technology for public transportation in highway corridor setting and not appropriate for level of expected ridership within the 20-year planning time-frame.
- Magnetic levitation: low community support, poor reliability in previous applications, and very low–cost effectiveness.
- Commuter rail: poor integration with ferry terminal and negative safety and traffic impacts.
The following pages will provide an overview for the proposed intersection improvements along the SR 305 corridor.
