The Donghai Bridge is a remarkable structure located in Shanghai, China. Spanning approximately 32.5 kilometers (20.2 miles), it connects the city of Shanghai to Donghai Island and serves as a vital transportation link for both vehicles and pedestrians. Completed in 2005, it is one of the longest sea bridges in the world. This bridge features a combination of viaducts and cable-stayed sections, allowing it to withstand harsh weather conditions, including typhoons. The Donghai Bridge not only facilitates travel but also supports economic growth in the region by improving access to nearby islands and enhancing maritime activities.
