Short line railroads are those lines that fall below regional railroad classification, are at least 350 miles and/or have revenue above $37 million but less than Class I standards, as well as all switching and terminal railroads. Washington State has nearly 1,400 miles of short lines, in both private and public sector ownership.
The story of the Manette Bridge is actually a story of the people of Manette and Bremerton in the beautiful pacific northwest in Washington state. In the late 1920’s, it was very apparent that a bridge was needed to connect these two communities. The high cost prevented any financial backing being offered on a city, state, or even federal level. That didn’t stop these determined people though. With great energy and enthusiasm, they enacted a unique plan that made the Manette Bridge on the day it was christened, truly, the bridge of the people.

This report responds to an inquiry by the State of Washington about the viability of natural gas as an alternative source of energy for transportation. The report is organized around responses to several key research tasks. These tasks are to: 1) Document the increase in supply of natural gas, estimate future price, and availability; 2) Assess the extent to which natural gas is likely to substitute for petroleum; 3) Estimate the extent to which price and performance effects will influence VMT trends in Washington State; 4) Estimate changes in GHG emissions in Washington State attributable to increased use of natural gas; 5) Estimate potential loss of fuel tax revenue attributable to substitution of natural gas for petroleum fuels.

This video shows a short clip of a worker replacing a cutting tool inside the SR 99 tunneling machine in January 2014. Crews working for Seattle Tunnel Partners (STP), WSDOT’s contractor for the SR 99 Tunnel Project, changed a number of tools during 158 hours of recent inspections performed under hyperbaric conditions. Tunneling experts now believe that the clogs and other factors contributed to the stoppage of tunneling on Dec. 6, 2013. As the project’s design-build contractor, it is STP’s responsibility to determine the best and most expedient way to resume tunneling.
