This is a list of the world's longest bridges that are more than in length sorted by their full length above land and water. The main span is the longest span without any ground support.
There is no standard way to measure the total length of a bridge. Some bridges are measured from the beginning of the entrance ramp to the end of the exit ramp. Some are measured from shoreline to shoreline. Others use the length of the total construction involved in building the bridge. Since there is no standard, no ranking of a bridge should be assumed from its stated length.
Numbers are merely estimates and measures in U.S. customary units (feet) may be imprecise due to conversion rounding.
