Help Build A New Bridge

Your input will help determine the best way to toll 520. To help you provide feedback, the 520 Tolling Implementation Committee is analyzing several scenarios; results will be available this summer. Some of the issues being considered include:

  • When tolls begin. Two potential scenarios are being analyzed: toll the existing bridge beginning when construction starts on the bridge facilities, or wait to toll the new bridge once it's completed. Tolling the existing bridge could help manage today's congestion, start saving toll revenue to help pay off the new bridge sooner, decrease costs, and possibly lower toll charges over the life of the project. The trade-off is that drivers could start paying tolls as soon as 2009 for a new bridge.
  • Whether to toll only the bridge or the entire corridor. A "single point toll" (like that used on the Tacoma Narrows Bridge) would only charge those who actually cross the bridge. Alternatively, tolling could occur on both ends of the 520 corridor, or at key on-ramps and off-ramps for 520 travel.
  • When to adjust toll rates. Tolls could vary by time of day, weekdays or weekend days, or as needed to keep traffic flowing smoothly.
  • How traffic diverts to other routes, modes, and times of day. If 520 is tolled, drivers may choose other routes or divert to other transportation modes or times of day to avoid the toll. This could mean more drivers go around the north or south ends of Lake Washington, or take I-90. If there is diversion, mitigation measures will be considered, such as investing in other corridors or tolling I-90.

Information from the analysis this summer will help you provide input to the 520 Tolling Implementation Committee on questions such as these:

  • Should there be tolls on the existing bridge to start building a new 520?
  • Should both the 520 and I-90 bridges be tolled to pay for a new 520 and improvements on I-90?
  • Should funding from tolls be used to expand transit service in this corridor?
  • What incentives would encourage you to take transit or carpool rather than drive alone?
  • Would you change your commute time to take advantage of a lower toll?
