I Dig the Tunnel

White text and an illustration of two eyes on a black background

In March 1987, the city of Seattle began the ambitious project of creating a 1.3 mile-long pair of tunnels for buses that would run through the downtown area of the city. The project took a little over three years and cost $469 million dollars to finish. The Downtown Seattle Transit Tunnels (DSTT) addressed a long-standing issue of traffic congestion in the city. Today, they are primarily used by the Link light rail, the city’s commuter trains. This button is promoting this project, with the phrase “I dig the tunnel” and a pair of eyes that represent the tunnels.
