His plan for the redevelopment of the site included three large office towers, a pedestrian mall, and an underground concourse where retail and business was to be located.
The plan called for an underground street system overlaid with mixed-use development, including a pedestrian mall, parking for 1,000 cars, and a bus terminal.
This five-block pedestrian mall was converted to allow the street to be reopened to traffic 29 years after the explosion, in 1997, as part of an urban revitalization effort.
