Population in the four counties of Central Puget Sound will have grown from the 2008 total of 3.6 million by another 1.4 million in 2040. Jobs will increase by 1.1 million, and – based on the region’s collective proclivities to date – total vehicle miles travelled (VMT) by more than 40 percent. Barring some big paradigm shift, the percentage of daily “passenger” work trips (freight vehicles not included) which occur on transit will grow from 8 percent of the current (2006) total to only 9 percent in 2040. For far more numerous non-work passenger trips, the transit market share stays at a scant 2 percent between 2006 and 2040, according to recent modeling. The vast majority of daily passenger trips occur in cars now and then. For work it’s more than four of five, for non-work, about nine of ten. (The rest are split between transit, walking and biking.) On the upside, there’s a lot more ride-sharing for non-work trips; plus, per-capita VMT will continue to stay flat; and we can shave a bit off the expected growth in total VMT by meeting (elusive) regional growth strategy targets.
These are some of the conclusions in a March 2009 background paper that’s part of the Puget Sound Regional Council’s “Transportation 2040” planning effort. Future projections may change slightly under new computer modeling in a draft environmental impact statement due out at month’s end. But you get the idea. The PSRC’s 2040 picture begs a huge question: what to do about it all. And, as we’ll see in a moment, it turns out that, away from the big transportation headlines it made last session, the state legislature has some ideas of its own.
My own take: A comprehensive approach to managing peak-hour highway capacity in Central Puget Sound should be launched by bravely establishing – and soon – a seamless regional system of variably-priced, automated and ultimately, corridor-length tolling on highways and major state routes. This must be folded into a broader plan to develop stable long-term funding for the region’s surface transportation network.

A committee hearing is schedule today for a bill (HB2211) introduced in the Washington State House of Representatives to effectively exclude the Interstate 90 bridge from an east-west bridge corridor tolling plan that would help fund replacement of the dangerously windstorm-prone and earthquake-prone parallel State Route 520 Bridge. The bridge replacement is estimated by the state to cost between $4.6 and $6.6 billion, as the Seattle Times has reported. Both the I-90 and SR 520 bridges connect Seattle with major Eastside job centers and will have to shoulder more traffic in coming years as population and employment grow, even if transit and vehicle trip reduction gain market share. Dropping I-90 from the corridor tolling plan is something with which the Read More ›
Earlier this month, Washington Gov. Chris Gregoire, Seattle Mayor Greg Nickels and King County Executive Ron Sims announced an historic accord to replace the seismically vulnerable Alaskan Way Viaduct on SR 99 along the downtown Seattle waterfront with an inland deep bored tunnel. (The last page of this state summary provides details on all project components and planned funding – the tunnel is expected to cost between $1.2 and $2.2 billion). State legislative approval is required. Now, Washington State Senate Majority Caucus Chair Ed Murray, State Senate Transportation Committee Chair Mary Margaret Haugen (pictured, right), the committee’s Ranking Minority Member Dan Swecker, and committee member Fred Jarrett of Mercer Island have introduced Senate Bill 5768 to get the tunnel built.

The need for public-private partnerships to help rebuild the nation’s overburdened and underfunded surface transportation network is growing. Even before gas prices spiked and gas tax hike prospects dived, the Washington State Transportation Commission was calling for P3s. They did so in this January 2007 report, and then again here. The January, 2007 report states that P3s should be closely examined as a potential strategy for completing planned major projects including the SR 520 floating bridge replacement, I-5 Columbia River Crossing, the State Route 167 extension to the Port of Tacoma, I-90 Snoqualmie Pass improvements, the State Route 704 Cross-base Highway in Pierce County, improvements to the state ferry system’s busiest dock, in downtown Seattle, Colman Dock, and for other Read More ›
