Marvin Road Interchange Improvements

WSDOT has big improvements on the horizon for the I-5/Marvin Road interchange. Starting summer 2018, crews will begin building a diverging diamond interchange (DDI). WSDOT Project Engineer Kim Mueller will discuss how this innovative and proven system efficiently accommodates more tra­ffic when compared to traditional diamond interchanges.
