Point Defiance Park is one of the largest urban parks in the United States. The Destination Point Defiance project improves park facilities and expands accesses to the waterfront. Washington Rock provided materials for a rail bypass, the zoo, and the breakwater peninsula. The bypass reroutes passenger trains away from the shoreline while the breakwater peninsula adds 11 acres of new park land. The zoo is replacing its aquarium, renovating two exhibits, and building a new Environmental Learning Center. Read about the latest updates on the Metro Parks Tacoma website.
