−	The construction of Karun Bridge was somewhat different than similar sized arches whereby a tower is usually erected on either side of the gorge and cables temporarily radiate out from it to support individual sections of the arch until the two halves are joined in the middle. With Karun, the roadway and support spandrels were built outward at the same time as the arch, eliminating the need for a high line. To prevent the two halves of the arch from falling into the gorge, several cables were attached from the road deck down to the arch within each spandrel panel. Once the next vertical spandrel support was built up to deck level and connected to another short span of roadway, then the arch rib was built out a little further and the process repeated itself. Once the two sides of the arch were closed in the middle, the temporary cable stays ~~are~~ no longer necessary though on the Karun spans they were left in place.

-The entire region around the Karun and Dez Rivers has grown into a giant collection of huge dams that began with the Dez Dam in 1963 shown in the upper left.  Karun Dams 1, 2, 3, 4 and 5 can be seen from left to right in the center of the map.
