6th Street Active Transportation Improvements Project
Project Status and News
Project Status: Pre-Design Phase (Currently pending selection of consultant for preliminary engineering)
The 6th Street Active Transportation Improvements Project has been identified as a priority improvement supporting safety and multimodal connectivity through a re-channelization (“road diet”) of the 6th Street corridor. 6th Street has been identified as the recommended east-west corridor for a re-channelization based on vehicle demand, topography, and availability of alternate parallel corridors including 11th Street and Burwell Street (SR 304). The proposed re-channelization for 6th Street generally includes conversion of the roadway from 4-lanes to 3-lanes with continuous on-street bike lanes. These improvements are planned to extend previously constructed on-street bike lanes on Kitsap Way (completed in 2022) to Washington Avenue providing improved east-west active transportation connectivity.
Project Location Map
Project Need and Purpose
Originally recommended in the 2007 Bremerton Non-Motorized Transportation Plan, a re-channelization of 6th Street was identified as an opportunity to take advantage of lower vehicle volumes through a conversion of the corridor from a 4-lane undivided roadway to a 3-lane roadway with a center two-way left-turn lane and bike lanes. The project has continued to be evaluated and highlighted as a recommended improvement as travel and development patterns have evolved including, most recently, through the adoption of the Joint Compatibility Transportation Plan. The project completes a critical east-west link in the City’s bicycle network providing access to existing and planned active transportation routes while improving roadway safety for all users.
Commonly referred to as “road diets”, this type of re-channelization seeks to maximize use of the existing roadway width to allow for other uses such as bike lanes. Implementation of these projects, where appropriate, has been shown to provide several road-user benefits:
- Improved Vehicle Safety – Reduced roadway conflicts points that contribute to rear-end, left-turn, and sideswipe crashes and improved driver visibility of oncoming traffic. The vehicle crash rate (crashes per 1 million vehicles) on 6th Street between 2014 and 2018 was more than twice the State and County average with approximately 31 crashes reported per year.
- Improved Bicycle Safety – Reallocation of the roadway to provide continuous bike lanes and bike-focused intersection improvements.
- Improved Pedestrian Safety – Reduced vehicle conflict points, improved pedestrian visibility, and a reduction in crossing distance across vehicle travel lanes.
- Operations Improvements – Minor impacts in peak hour vehicle travel times due to the re-channelization are balanced by more predictable traffic flow and improved operations at side streets and driveways.
- Improved Quality of Life – By transforming the existing roadway to integrate additional active transportation options supporting a healthy and vibrant community.
Project Scope of Improvements & Considerations
The primary scope of project improvements includes a re-channelization of 6th Street beginning east of the 11th Street & Kitsap Way intersection and ending at the 6th Street & Washington Avenue intersection. The project is anticipated to include pavement markings, signage, intersection improvements, traffic signal modifications, and other associated minor roadway improvements supporting the re-channelization.
The following considerations must be evaluated as part of the design:
|Due to the length of the 6th Street corridor, number and location of intersections, and existing pavement width bike lane design will require significant evaluation to maximize safety, access, and user comfort. Use of buffered or physically delineated bike lanes to be evaluated. Green pavement markings should be designed at conflict points and signalized intersections
|Signalized Intersection Operations
|Based on intersection traffic data collected at intersections during peak morning and afternoon travel times (including traffic growth projections), minor pavement widening may be needed to accommodate separate vehicle right-turn lanes. Failure to consider separated turn lanes at signalized intersections with high peak hour turn movements can result in unnecessary intersection delays / queueing and reduce overall intersection safety.
|Non-Signalized Intersection Operations
|Non-signalized intersections (especially those with an offset, such as Olympic Avenue and Hewitt Avenue) must be evaluated for turning restrictions due to the addition of a center two-way left-turn lane to avoid head-on vehicle turning conflicts. Other intersections which are located near existing signalized intersections must also be evaluated. Where turning restrictions are proposed, alternate routing for local traffic must be evaluated.
|Traffic Signal Modifications
|The project includes 8 existing signalized intersections including one (1) HAWK pedestrian signal at High Ave. In addition to modifying signal equipment to detect bicycles, signal indications and signal timing must be modified to reflect the changed lane configuration. Locations of signal poles may be impacted if minor pavement widening is necessary at intersections.
|While pedestrian crossings will remain unchanged at signalized intersections, the addition of a center two-way left-turn lane may provide an opportunity for a proposed (or future) marked crossing between signalized intersections. Early evaluation of these pedestrian crossing improvement opportunities is needed.
|Existing on-street parking currently exists on 6th Street between Park Avenue and Washington Avenue. Re-channelization and inclusion of bike lanes will require coordination on reduction and reorientation of on-street parking.
|Where minor pavement widening is required to maintain intersection operations, additional right-of-way may be needed to physically construct the improvements. Acquisition of right-of-way can have a significant impact on project schedule.
|Other improvement considerations include vehicle travel lane tapers, roadway lighting, topography, access for city maintenance operations, bike lane conflicts at bus/transit stops, vehicle travel lane widths, and compatibility with future improvements such as the Naval Ave Bicycle & Pedestrian Enhancement Project.
The FY 2024 City of Bremerton Budget includes Transportation Capital Funds to advance the engineering design phase of the 6th Street Active Transportation Improvements Project. Funding for right-of-way acquisition (if required) and construction has not been secured. Estimated project cost by phase is shown below:
While the estimated construction schedule for the project will be subject to funding for the construction phase, the preliminary engineering phase is currently underway. Updates on the project schedule will be provided once known and public outreach activities related to the project will be listed under the Project Status and News section.
