Physical bridge protection systems designed to prevent catastrophic collisions are expensive and represent a "significant" share of overall construction costs. Therefore, alternatives are typically considered during the design phase: [10] improving the navigational aids to reduce the probability of a catastrophic impact (60-85% of the ...
This is a list of the world's longest bridges that are more than 3 kilometers (1.9 mi) in length sorted by their full length above land and water. The main span is the longest span without any ground support. Note: There is no standard way to measure the total length of a bridge. Some bridges are measured from the beginning of the entrance ramp ...
