DOT (graph description language) DOT is a plain text graph description language. DOT graphs are typically files with the file extension gv or dot. The extension gv is preferred to avoid confusion with the extension dot used by early (pre-2007) versions of Microsoft Word. Various programs can process DOT files.
The Lake Pontchartrain Causeway, or the Causeway, consists of two parallel bridges crossing Lake Pontchartrain in southern Louisiana, United States. The longer of the two bridges is 23.83 miles (38.35 km) long. It is the longest bridge in the world that runs continuously over water.
The 26.4 mile-long Qingdao Haiwan Bridge - the world's longest bridge over sea water - opens to traffic in China. The marathon-length Qingdao Haiwan Bridge would easily span the English Channel and is almost three miles longer than the previous record-holder, the Lake Pontchartrain Causeway in the American state of Louisiana.
