Lake Urmia lies between West Azarbaijan and East Azarbaijan provinces. Tabriz is the biggest city to its east, and Urmia is the biggest city to its west. The shortest way between these cities is to go round the lake. In 1970s a project was started to create a bridge across the lake. This project was canceled when Islamic Revolution happened in 1979. However, the project was started again in 2000s; it is planned to be finished by the end of 2007.
