DALLAS—Like many downtowns across the country, Dallas lost momentum in the 1960s as new freeways and affordable suburban middle-class homes sucked the growth out of the central business district. Many businesses followed as office buildings rose on the suburban prairies. Before the 60s were over, the city council tried to stop the outward tide by adopting the recommendations of urban planner Vincent Ponte, who designed a system of downtown tunnels and underground retail shops linking the major buildings.
