The U.S. Department of Transportation announced Friday its approval of a $1.33 billion loan to Sound Transit for its East Link extension from Seattle to Redmond.

DOT is also contributing $74.7 million in Federal Transit Administration funds and $14 million in Transportation Investment Generating Economic Recover V grant funding toward the $4 billion East Link project.

“The East Link Project will give the people in the Seattle area better access to jobs, education, and other opportunities,” said U.S. Transportation Secretary Anthony Foxx in a statement. “This project will have a significant impact on the entire region and expand a world-class transit system.”
