Obelisk

In Miami, if not in other places of the US as well, you can see a new structure that springs up in new highways that looks like an obelisk. That is a new way to support the large signs posted on expressways. They are also designed to support the new systems of toll-by-plate. Here is a new one on SW 104th street holding the direction to expressway 874 going North. If it has to extend to the other side, another obelisk is erected and the orange cylinders are connected to reach it as far as needed.
