By several standards, the transportation network of Washington state is creaking under the pressures of age and economic growth.
Drivers traveled 6.4 percent more highway miles than two years ago and 4.8 percent farther overall. This increase fueled a 22 percent increase in urban delays due to congestion and added carbon pollutants that cause global warming.
Highway pavement is wearing out faster than the Washington State Department of Transportation (WSDOT) can maintain it.
Three Olympic-class vessels including the new Chimacum kept the ferry system afloat, but only 87.5 percent of statewide trips left on time this summer, missing the 95 percent goal. Parts of older ferries needed emergency repairs, leaving some routes with fewer boats, or smaller boats that took longer to load.
Never miss a local story.
And traffic killed 537 people last year, far above a goal set by safety advocates and a sign that Washington’s long-term gains have stalled.
These data appear in the third quarter 2017 WSDOT Gray Notebook, which mostly covers 2014-2016.
To be sure, the update contains good news.
Bridge maintenance is doing fine. Fewer than 10 percent qualified as poor, based on federal standards used by bridge inspectors.
Ferry-terminal conditions improved to 88 percent fair or good, as passenger lounges, trestles, pilings and gangways were renovated.
And WSDOT’s highway-incident teams cleared 58,235 fender-benders, objects and stalled cars within an average 13 minutes — a service that prevents untold numbers of secondary crashes.
But Gov. Jay Inslee, his predecessor Christine Gregoire, and the Legislature have set lofty goals the state is currently failing to reach:
▪ A “Target Zero” program to eliminate traffic casualties by 2030.
To stay on pace, fatalities would need to be only 416, instead of the 537 lives lost in 2016.
Distracted driving is being blamed for reversing years of safety progress. A new law against using handheld devices behind the wheel took effect in July, but it’s routinely ignored. Seattle police and state troopers observed a grace period and will start issuing $136 fines in January.
▪ Greenhouse gases are supposed to be slashed to 1990 levels by 2020, and then reduced again by half by 2030.
Transportation causes 42 percent of the state’s carbon emissions. From 2010-13, which included the tail end of a recession, the state was on track. No longer.
“The economic growth in our region, combined with low gas prices and low unemployment, are the main reasons we’re continuing to see growth in vehicle miles traveled,” said WSDOT spokesman Lars Erickson.
“The transportation system has busted through the state’s emissions goals,” said Clark Williams-Derry, research director of Sightline Institute, a Seattle-based environmental research group.
Cheaper gasoline is a major factor, similar to national trends to drive farther and buy larger vehicles, he said.
Prices including tax fell 32 percent from $3.61 to $2.47 per gallon from 2014-16, the state report says.
Sightline supports a rapid shift to electric vehicles and carbon pricing through a use tax, highway tolls or other means.
“As long as we let people use the roadspace for free, and the atmosphere as a free dumping ground, we’re going to end up with more driving,” he said.
Lawmakers boosted gas taxes 11.9 cents in 2015-16, while dedicating $10.8 billion to road widening and maintenance. Urban voters passed the $54 billion Sound Transit plan to build rail and bus lines.
Inslee and WSDOT hope to increase electric vehicle numbers from 25,000 to 50,000 by 2020, by offering roadside charging stations and tax breaks.
Electric technologies are the best solution to encourage a greener fleet, instead of “left-wing” proposals to tax motorists harder, said Todd Myers, environmental analyst for the Washington Policy Center. “One mile traveled in a Hummer is very different from a mile in a Tesla,” he said.
Transit ridership increased 2 percent statewide. In dense, central Seattle, non-WSDOT data show that at least 47 percent of commuters ride transit. Bus, train and ferry ridership in the metro area rose 4 percent last year — while falling in nearly all other U.S. regions.
Amtrak Cascades suffered from record rain that caused mudslides, reducing on-time arrival to only 33 percent in February, March and April, and 56 percent for the year ending in June.
Later this month, a direct bypass track opens from Tacoma to DuPont, which should improve speed and reliability, compared to the old scenic but fickle trip around Point Defiance and The Narrows, mixed with freight trains.
As for road conditions, a longtime backlog of needed preservation work increased to $403 million in 2015.
Drivers can expect several weekend closures in 2018 to replace Interstate 5 concrete panels in Seattle — which were typically built in the 1960s — similar to this year’s summer of slowdowns in SeaTac and Tukwila.
Another trouble spot is Snoqualmie Pass, where motorists tapped their brakes for an hour or two all summer. Contractors fell behind their expected rate to fix Interstate 90 bridges, including the steel-arch bridge west of the summit, despite working past Labor Day. Erickson said they’ll strive to finish the whole corridor in 2018, starting well before Memorial Day.
Highlights from the latest Gray Notebook:
▪ Total miles traveled rose 4.8 percent from 2014 to 2016, to a record 61 billion miles.
▪ Traffic deaths declined only slightly, from 551 in 2015 to 537 in 2016. Serious injuries increased from 2,100 to 2,209 statewide.
▪ Amtrak Cascades trains arrived on time only 56 percent of trips last year.
▪ Ferry-terminal quality improved, but the backlog of vessel parts overdue for replacement grew $30 million. New boats and ongoing repairs kept that from getting worse.
▪ Highway-response teams cleared 58,235 incidents in 2016. The workload averaged one callout every eight minutes this summer.
