There was a website that outlined all the projects with completion dates and a calculator where each person could look up how much it would cost. It is still available at www.soundtransit3.org.

Sound Transit 3/Regional Proposition 1 was also very much opposed by the Seattle Times editorial board who's paper published dozens of articles, columns and editorials in the months before the election. Most of these highlighted the costs and minimized the benefits.

The issue was one of the most hotly contested local issue before voters in Puget Sound.
