The King Countys DNS (Determination of NonSignificance) announcement follows the Federal Highway Administration’s FONSI (Finding of No Significant Impact), which was released in June, and is another necessary step before work gets underway. Gotta love those government acronyms! The document includes a slightly more concrete statement about when construction will occur.

“The project construction will take approximately 2.5 years between February and December subject to weather and timing restrictions to protect wildlife. It is anticipated that the project will be advertised in the fall of 2013 and that construction would begin in April 2014. The exact construction timing or schedule will be determined by the contractor.”

Nitpick: The indicated location of the three bridges to be? replaced are incorrect on this King County map. They are correct in the FONSI materials.
