Updated 1:19 PM Portlanders living near the Rose Quarter sued two federal transportation agencies Monday morning, demanding they force Oregon officials to look closer at the environmental effects of a contentious plan to expand Interstate 5. Three Portland advocacy groups, including a neighborhood association, filed the lawsuit in federal court this morning against the U.S Department of Transportation and the U.S. Federal Highway Administration. In the lawsuit, they accused the feds of failing to hold the Oregon Department of Transportation responsible for conducting a thorough environmental impact analysis of a highway project that would widen I-5 to at least 120 feet as it passes Moda Center and Harriet Tubman Middle School.
