Near-term Improvements
The near-term improvements described in the final report -- the SR 99 North Route Development Plan -- are recommended to the City of Seattle and King County Metro for implementation in the near future as warranted by safety and congestion needs.
State law RCW 47.24.020 states that cities with a population over 22,500 are responsible for traffic operation improvements -- traffic signals, left-turn restrictions, parking restrictions, and bus lane designations. Therefore, although SR 99 N./Aurora Avenue N. is a state owned roadway, traffic operation improvements on SR 99 N./Aurora Avenue are the responsibility of the City of Seattle. King County Metro is responsible for funding and operating bus service on SR 99 N./Aurora Avenue N.
WSDOT is responsible for repaving SR 99 N. /Aurora N. and approving the City's channelization plans and traffic signal installations. Day to day traffic operations management is the responsibility of the City of Seattle. With an understanding the traffic operation improvements are the responsibility of the City of Seattle and transit improvements are the responsibility of King County, the near-term improvements are recommended to promote a safer and more secure corridor, and support long-term mobility for corridor users.
Long-term improvements
The long-term improvements are categorized by geographic area and can be viewed by clicking on the area of interest on the map.
Long-term improvements are recommended for implementation between 2006 and 2030 - primarily in conjunction with private redevelopment and are based on the results of extensive public involvement, interagency cooperation, and technical analysis. These improvements, when implemented, will enhance the function of the SR 99 North Corridor as a local and regional multi-modal transportation facility.
Prior to developing the long-term recommendations, the Study Team, the Joint Steering Committee, local agencies, neighborhood groups, the business community, and the general public evaluated a variety of improvement options. From this evaluation, the draft improvement recommendations were selected and then revised per comments from the aforementioned parties. The final recommendations presented here are the result of this process.
With the exception of the Aurora Bridge (which would be a specific project) all the long-term recommendations would take place over time in conjunction with property redevelopment. As redevelopment occurs, curb lines and sidewalk edges would be set to the future cross-section of each location ultimately resulting in a new roadway width. The proposed future right-of-way widths that would be used to accomplish this are similar to the current right-of-way requirements used by the City of Seattle for new developments |
