This rapidly evolving stretch of Miami's signature thoroughfare embodies the highest of human aspirations and the lowest of human avarice. A few landmarks heading north from Sixth Street: The Freedom Tower and its symbolic representation of mankind's yearning for liberty; a hulking American Airlines Arena as proof that power and money always trump the public's interest; Bicentennial Park, now protected and awaiting rebirth, standing as a very rare victory for that public interest; across the street, a string of parcels bought by a politically connected speculator who expects their value to skyrocket; just beyond the noxious concrete mass of I-395, the grandiose Performing Arts Center rising amid hopes of a cultural renaissance and growing fears of insolvency; and approaching the mile marker, construction cranes erecting a concrete wall of condominiums that will permanently block public access to the bay while enriching developers enabled by politicians whose vision of the future does not extend beyond the next election.
