Public amenities of the year-round harborwalk include a picnic park, paths for bikers and pedestrians, viewing decks, waterfront dining and retail, a performance lawn, floral displays, boat docks, and public art. After a remediation process to clean the site, Wynn Resorts constructed an integrated resort with a hotel, a harborwalk, restaurants, a casino, spa, retail outlets, and meeting and convention space. It opened on June 23, 2019, at a total cost of $2.6 billion. Its development rehabilitated a 33-acre parcel of land previously used for industrial purposes. The resort is in a commercial-industrial area on the Mystic River, about 5 miles (8.0 km) from downtown Boston.
