Bay Area Looks To Future With Regional HOT Lane System

Slight decreases in traffic congestion due to the economic downturn are no reason to curtail aggressive transportation planning for looming population and employment growth in major metro regions. Despite the most fervent wishes of some planners, metro region growth in coming years will continue to be more away from, than to, high-density urban neighborhoods. This is due to due to several factors. For one, first- and second-ring suburbs have become regional employment centers, and cities in their own right. They are where people increasingly work, shop, play – and if finances permit, live. Examples in Central Puget Sound include Bellevue and Redmond to the east of Seattle, and (more affordable) Kent and Federal Way to the city’s south. Second, there Read More ›

State Treasurer: “Very Difficult” To Fund 520 Bridge Without I-90 Tolls

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 ›

A Stimulus For States and Regions To Own Surface Transportation

The much-hyped federal economic stimulus package isn’t looking like it will do all that much for surface transportation. The New York Times reports that the House stimulus bill contains a scant $30 billion for roads and bridges and $10 billion for transit. Turns out most of the infrastructure spending in the bill is not for surface transportation. The new administration has weighed in, supporting the bill. Washington State would get $530 million for highways, roads and bridges and $216 million for transit from the bill, according to D.C. correspondent Les Blumenthal. To put that in context, we have about $38 billion in unmet transportation funding needs, as shown on p. 5 of this overview from the Washington State Transportation Commission. Read More ›

Cascadia-Arup Report: Deep Bore Tunnels @ $200M-$700M Per Mile

A report titled “Large Diameter Soft Ground Bored Tunnel Review” has just been released by the transportation think tank Cascadia Center and global engineering and consulting firm Arup. It strongly suggests that a new state cost estimate for a deep bored tunnel of approximately two miles to replace the aging Alaskan Way Viaduct could be greatly inflated. The state’s Alaskan Way Viaduct Stakeholders Committee (SAC) pegs the cost of the one-mile tunnel at $3.5 billion, but the Cascadia-Arup report surveyed deep-bored vehicle tunnels worldwide and found costs typically fall in the range of $200 million-$700 million per mile, for large diameter soft ground bored tunnels, created with assistance of a tunnel boring machine (pictured below at right).

West Coast Mobility Solutions Key, Speakers Say

Last Thursday June 26, our Cascadia Center hosted the West Coast Tolling and Traffic Management Workshop at the Bell Harbor Conference Center on Seattle’s waterfront. Speakers came from up and down the West Coast, Washington, D.C. and London to share with a capacity crowd the latest developments in regional tolling policy, tolling and traffic management technology, and transportation public-private partnerships. First, our own quick-take on the event. Then some handy links to media coverage, and speaker PowerPoints. Discussion Highlights Democratic State Senator Ed Murray, a member of the legislative majority in Olympia and the ranking majority member of the Senate Transportation Committee, voiced strong support for public-private partnerships as one important tool to help fund the approximately $50 billion backlog Read More ›
