A proposal to expand light rail in the Puget Sound region is up for a vote today. The Sound Transit board will decide whether to put the plan on the November ballot. The proposal would add 34 miles of rail in King, Pierce and Snohomish counties. The price tag is nearly 18 billion dollars. Supporters of the plan, including Sound Transit Board Chairman Seattle Mayor Greg Nickels, say the proposal is the best shot at relieving the area's gridlock. KUOW's Derek Wang spoke with Nickels about the details. This interview was produced by Liz Jones.
