Sound Transit will extend its light-rail planning two extra years until 2026, and spend $32.8 million more, while consultants study new downtown and South Lake Union station sites promoted by Seattle Mayor Bruce Harrell and King County Executive Dow Constantine.
That money will be paid to HNTB Corp., which will write a final environmental impact statement that’s required by federal law, and will conduct preliminary engineering, for the proposed $11.1 billion light-rail route from Ballard to Sodo.
