The photo on the left is what Downtown Miami looked like in 1977. Brickell Key was just an empty island in the process of development. The site American Airlines Arena is currently on was used as a Port and Bicentennial Park was in its infancy. Fast forward to 2015 and the Frost Museum of Science is under construction and many condos and offices have filled Biscayne Boulevard and the Downtown core. Biscayne Boulevard has also been widened to support the traffic. In both photos the one constant that has remained is the iconic Freedom Tower.
