We have talked a lot about transit across SR-520 over the last few months, but I don’t think we have ever mentioned what the adopted plan for the corridor is. The plan calls for increased bus service during SR-520 construction with BRT service phased in afterwards. The plan also touches on the Montlake Triangle and light rail over SR-520. Both of these sections are somewhat redundant, as imminent planning or recent studies cover these issues in more detail.
Five BRT lines (see map above) would have two-ways service with 7- to 10-minute headways during peak periods, 15-minute headways mid-day, and 15- to 30-minutes headways in the evenings. Under this plan the 255 and 271 become BRT routes. The plan says that $16.5 million per year (in 2008 dollars) will be needed to fully fund the additional 130,000 service hours identified in the plan. I believe that 38,000 to 48,000 service hours have already been funded through ST2 and the ferry district tax, but money for another ~90,000 service hours is needed. This lack of identified funding sources is in my opinion one of the largest unaddressed issues for transit in the SR-520 planning. A funding plan (supported by toll money?) has to be written in stone or else I have very little confidence that the hostile state leadership will allow or authorize more funding.
