(WSDOT’s newest animation showing the tunnel plan and other area components)
In the Alaskan Way Viaduct project offices downtown this morning, project leader Ron Paananen led a media briefing meant to underscore the point in our headline – why you should take the time to comment on the Supplemental Draft Environmental Impact Statement for the tunnel, officially released a week ago. Much of the discussion centered on the fact project managers believe the tunnel has to carry a toll to raise hundreds of millions of dollars – but, as the SDEIS points out, if the tunnel is tolled, there will be almost as many drivers avoiding it as drivers using it – about 45,000 daily for each. And, according to the summaries handed out at this morning’s briefing, that would affect West Seattle drivers: Not just the obvious effect, the fact that West Seattleites going downtown won’t use the tunnel because it has no exits, but the fact that the “diversion” (tunnel avoidance) will put enough traffic on other streets that it’ll increase the travel time. This morning’s presentation included:
With a tolled bored tunnel, the West Seattle to downtown and Woodland Park to downtown trips’ travel times could be 3 to 4 minutes longer than without tolls.
“No toll” is apparently not an option, but the new report does study three levels of tolling (ranging between $1 and $5 “in 2015 dollars), including one option that would only raise about a fourth of the money. It also notes that the tunnel still puts more traffic on city streets than they carry today, since it is not designed for as much capacity as the current Alaskan Way Viaduct carries – two lines in each direction compared to the current three. So if so many people would avoid the tunnel, how will gridlock be averted? The “potential tools for traffic management” listed at the briefing include:
Fine-tune toll-rate structure throughout the day
City street operations
Transit priority into and through downtown
Pedestrian and bicycle improvements
Manage parking on downtown streets
Seek additional transit funding
Active Traffic Management (ATM)
The state has started to dabble in the latter – variable speed limits, among other things. Meantime, it was asked whether tolls would continue after the loans were paid off; “That’s up to the Legislature to decide,” Paananen replied. Tolling and traffic are just part of what the SDEIS looks at; it also discusses tunnel-construction effects, such as five and a half years of 24/7 construction work with “17 potential staging areas.” But the biggest direct West Seattle effects are those travel times; you will be able to comment, and ask questions, at the public hearing/open house coming up at Madison Middle School, 6:30 pm November 16, and you can also have your say all these different ways.
