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.

Thursday, November 28th, 2013Our hometown Seattle will soon be eclipsed by another city (a more conservative one!) when it comes to bicycle infrastructure.
