Seattle, WA: Fixing the Tunneling Machine

This video shows a short clip of a worker replacing a cutting tool inside the SR 99 tunneling machine in January 2014.

Tuesday, April 9th, 2013

The International Bridge, Tunnel and Turnpike Association (IBTTA)
The funding crunch facing America’s transportation infrastructure has made it crucial for our cities, counties, states and regions to find innovative ways of funding our mobility.
