One of the first open-air malls, Broadway Shopping
Center was built on undeveloped land at Main Street (Highway 21) and Mt. Diablo
Boulevard (Highway 24). When it opened in 1951, the 38-store center had Sears
and J.C. Penney, a Lucky grocery store, and 1,500 free parking spaces. Within a
few years, the mall was expanded to the south and a new department store –
Capwell’s (now Macy’s) – was added.
