German orthography
Compound words, including nouns, are written together, e.g. "Haustür" (Haus+Tür; house door), "Tischlampe" (Tisch+Lampe; table lamp), "Kaltwasserhahn" (Kalt+Wasser+Hahn; cold water tap/faucet). This can lead to long words: the longest word in regular use, "Rechtsschutzversicherungsgesellschaften" ("legal protection insurance companies"), consists of 39 letters; while the longest German word ever published ("Donaudampfschiffahrtselektrizitätenhauptbetriebswerkbauunterbeamtengesellschaft", "Association for subordinate officials of the head office management of the Danube steamboat electrical services") has 79 letters.
Bundesautobahn 40
It has officially been named Ruhrschnellweg (Ruhr Fast Way), but locals usually call it Ruhrschleichweg (Ruhr Crawling Way) or "the Ruhr area's longest parking lot". According to "Der Spiegel", it is the most congested motorway in Germany.
In the city of Essen, a Stadtbahn service operates on the median of the A 40 between Tunnel Ruhrschnellweg and Mülheim-Heißen. Between the Essen-Huttrop and the Essen-Kray junctions, there is a guided bus system called Spurbus.
