The Urmia Lake Bridge is a bridge in northern Iran. It crosses Lake Urmia and connects the provinces of East Azerbaijan and West Azerbaijan. The highway was completed in November of 2008. The bridge is the largest and longest bridge project in Iran. The bridge reduced the driving distance between Tabriz and Urmia by 135 kilometres (84 mi). This bridge has an important role in the development of the cultural exchanges and tourism and trade between the two provinces of East Azerbaijan and West Azerbaijan and saves time and fuel consumption and reduces road accidents.
