Poor neglected Photo Friday...it's been a while hasn't it? Let's kick things off with this stunning beauty:

The double-deck Alaskan Way Viaduct, a fixture on Seattle’s downtown waterfront for more than five decades, was already showing signs of wear and tear when the last major earthquake struck in 2001. That 6.8 magnitude seismic event further weakened the structure by damaging its joints and columns and causing sections to settle into the loose fill soil in which it was built.
In the years since, crews have kept a close eye on the viaduct through quarterly inspections and have strengthened several columns to prevent further damage to the structure, but the threat of another earthquake was always present. During this time new soil data and a better understanding of local and regional seismic behavior clarified exactly how vulnerable the viaduct is to another earthquake. In 2007 we released a report that concluded there is a higher chance – specifically, a one in 10 chance in the next 10 years – of an earthquake occurring that could cause portions of the viaduct and adjacent seawall to collapse. The vulnerability analysis is available on our Web site.
Today, it’s no hallucination. There is such an agency. It’s WSDOT and their Ask the Traffic Team page.
That car was was my first love.
George Jetson would be jealous. Sure, he flew to work in a domed commuter pod, but could his skyway tell him where the congestion was before he was stuck in it? I think not. But that’s exactly what we’re working on for some of the busiest highways in the Seattle area.
Drivers who use SR 410 near Naches are facing a traffic nightmare after a massive Oct. 11 landslide blocked a half-mile section of the roadway. The slide was powerful enough to demolish the highway and carry tons of dirt, pavement, and debris into the Naches River, shifting it off course. That new course took it right over the Nile Loop Road on the other side of the river, cutting off another access point for local residents.
Note to self: Buy snow shovel...Just in case.
Have you ever needed to travel over I-90 Snoqualmie Pass at night and tried to pull up WSDOT’s mountain pass traffic cameras only to see a pitch black image with the occasional car headlight?
Well, not anymore. WSDOT just completed installing eight new low-light traffic cameras on I-90 west of Snoqualmie Summit to Cle Elum. The new traffic cameras have infrared illuminators that provide around-the-clock views of highway conditions – even during a midnight snow storm!
