Questions over digital signs downtown

The American Airlines Arena has a state-of-the-art electronic mesh
sign, showing images promoting various events, the kind of digital
advertising developer Mark Sifffin envisions in his plan for two high-rise, electronic media towers
north of the arena. There are questions, however, over whether such
signs meet Miami-Dade County and City of Miami codes, ones that need to
be answered as the city decides how Miami’s skyline will shape up in
the next decade. Miami-Dade County commissioners have sought advice
over whether the arena sign is legal. [SFBJ]
