1968. Can you tell?
The mall contained 55 stores and was anchored by a Bashas' supermarket, Diamond's department store (later Winston's, then ZCMI), and JCPenney. The mall first encountered problems when the large Metrocenter mall opened in north central Phoenix in 1973. Despite this, Tri City Mall continued to prosper until several additional malls (among them Fiesta Mall) were constructed in the 1970s and 1980s.
The mall closed in 1998 and was demolished to make way for a new strip mall shopping center, Tri-City Pavilions. The last standing Tri-City Mall store (the gutted remains of JCPenney) was demolished in April 2006 to make way for the Main at Sycamore Metro Light Rail transit station.
A short life, but it was spared the decline.
