DUPONT – On the heels of opening the new southbound Interstate 5 exit 119 to Steilacoom-DuPont Road, crews are making final preparations to fully open the state’s third diverging diamond interchange. The new I-5 overpass will provide access between DuPont and Joint Base Lewis-McChord in Pierce County. Demolition of the old overpass is currently scheduled for April 3-4, and will require two overnight full closures of both north and southbound I-5.
