The Bloukrans Bridge is an arch bridge that spans over two small peaks. It is the tallest road bridge on the continent, towering 708 ft in the air. It was built in the early 1980's, and designed by Liebenberg & Stander Western Cape Ltd. It crosses the Bloukrans River, and is made from reinforced concrete. Some of the design constraints on this bridge had to be that obviously it would be able to hold itself up. It also had to be able to hold the road traffic that goes on top of it. Because of the fact that it is very near to the sea, the engineers had to make it withstand wind, as well as thermal stress due to an average temperature of about 86 degrees Fahrenheit in South Africa.
Overall, I think that this bridge is fascinating because while it has a very simple design, it is also very eye catching due to the setting around it. It is also the highest place in the world with commercial bungee jumping.
