From Next City:
In the 1970s, a set of elevated highways began rising up near the shore of Cape Town, South Africa. Known locally as the “Foreshore freeways” after the industrial area through which they run, these roads separate Cape Town’s city center from its port much as other urban highways do on waterfronts the world over.
What distinguishes the Foreshore freeways, however, is that they were never completed. … 
The non-profit think tank Future Cape Town today released the results of an informal poll finding that nearly half of respondents voted to demolish the Foreshore freeways. …
Respondents had five options for the question of improving the Foreshore freeways. Coming out on top, with 48 percent of the vote, was the option of tearing down the roads to reconnect Cape Town’s central business district with the waterfront. Another 29 percent said the unfinished structures should become museums, while 19 percent voted convert them into elevated green spaces à la the High Line. Only 8 percent said that the city should work to activate the space below the freeways.
