Bremerton, WA: The Manette Bridge Documentary

Bremerton, WA: The Manette Bridge Documentary

By the summer of 2010 in Manette, Washington, the people of this quiet community by the water had learned that soon they would have to say goodbye to an old friend–a friend that had been with them for 80 years and had served their community year-in and year-out; a strong, faithful companion who, now ravaged by time and the elements, would be unable to continue. That friend was simply known as the Manette Bridge.

Report Card for D.C.’s Infrastructure

Monday, January 18th, 2016
Report Card for D.C.

AMERICAN SOCIETY OF CIVIL ENGINEERS (ASCE)
NATIONAL CAPITAL SECTION
The District of Columbia has 265 bridge structures; 226 of the bridges are owned by the D.C. Department of Transportation (DDOT) and the remaining 39 are owned by the National Park Service (NPS). The average age of a bridge in D.C. is 58 years, and 80% of the bridges will need to be replaced or rehabilitated in the next 10 years. However, the District made significant strides to reduce the number of structurally deficient bridges from 8% to 3% in just three years. Despite this progress, more than 220,000 trips are taken over a structurally deficient bridge every day and a quarter of bridges have at least one major component in fair condition.

Seattle, WA: The Part of the Tunnel Built WITHOUT Bertha

Approximately 20 percent of the SR 99 tunnel was designed to be built without Bertha, the SR 99 tunneling machine. Seattle Tunnel Partners bored more than 1,000 feet of tunnel before they stopped to repair Bertha. Since then, they have built an additional 1,200 feet of tunnel using cut-and-cover tunnel construction. This video gives a close-up look inside the newest part of the project to learn more about the tunnel built without Bertha.

Washington DC Vision Zero: INJURY CRASHES 2010-2014

DISTRICT DEPARTMENT OF TRANSPORTATION
The goal of Vision Zero is straight-forward: zero fatalities and serious injuries in our transportation system, because no loss of life is acceptable. Vision Zero was first adopted in Sweden in 1997. Since then, fatal and serious injuries in Sweden have consistently declined, despite a regular increase in people driving, walking, biking, and using transit.

Seattle, WA: The Big Road Fix

Seattle, WA: The Big Road Fix

After an earthquake revealed its instability in 2008, the state of Washington announced it was going to tear down a crumbling double-decker stretch of freeway known as the Alaskan Way Viaduct. After a heated debate, the state decided to use a giant drill named “Bertha” to deep-bore underground tunnel to replace it. Seven years later, the Viaduct is still up, Bertha is stuck underground, and the city’s residents have been left to wonder whether this major project will ever be worth the time and money spent on it.

Washington D.C.’s Protected Bike Lane Treatments on 1st Street

Earlier this year, 1st Street in Washington D.C. was transformed into a protected bike lane with a myriad of separation techniques that all seem to work very well and feel incredibly safe. About half the lane is done with concrete median prortection while other sections are done with green paint, plastic bollards and armadillos which seem to prevent traffic from encroaching on the lane. What is truly impressive is the now much more the narrow streets deliberatly funnel traffic more slowly and lead to a street that feels welcome in a Vision Zero world.

Washington, DC: Bicycle Infrastructure and Traffic Congestion

Figure 1: Bikeshare Trips (departures and arrivals)

RESOURCES FOR THE FUTURE
A new mechanism to reduce urban traffic congestion that is currently gaining traction for its purported cost-effectiveness, environmental-friendliness, and positive health impacts is the adoption of citywide bicycle-sharing systems. This infrastructure provides an alternative to driving for short trips and extends the existing network of public transit within a metropolitan area. Further, bicycling infrastructure augments the environmental bona fides of densely populated urban areas (Kahn, 2010). If bikeshares reduce traffic congestion, they may provide a low-cost policy lever to reduce automobile externalities in urban areas.

Washington State DOT: How To Move a Bridge (Time Lapse)

Over the weekend of Friday, Aug. 7, 2015, crews relocated the obsolete 379-ton 1920’s era Puyallup River bridge about a quarter-mile to WSDOT property. WSDOT’s goal is to recycle the truss by offering it for another purpose. If unsuccessful, WSDOT will recycle the steel.
