Valiasr Street is the longest street in Middle East, and was reported as one of the longest in the world by former BBC (now Al Jazeera) journalist Rageh Omaar during the television documentary "Welcome to Tehran. It is tree-lined and divides the metropolis of Tehran into western and eastern parts. The street is considered one of Tehran's main thoroughfares and commercial centres.
The street was built by Reza Shah Pahlavi's order and called the Pahlavi Street.After the 1979 Islamic Revolution the street's name was changed initially to Mossadeq St. (in reference to former nationalist prime misnister Mohammad Mossadeq) and later to Valiasr (a reference to the 12th Shi'ite Imam). Valiasr Street is the hub of different activities in Tehran and innumerable shops and restaurants as well a large number of parks(like Mellat Park ), highways, cultural centers etc. are situated along this long avenue.
Valiasr runs from the Tehran's railway station in the south of the city to the Tajrish square in the north.
Valiasr runs for 12 miles (19.3 kilometers), north to south, and is filled with traffic at all hours, even until the early hours of the morning. The shops stay open late and the kiosks sell fresh fruit juice and coffee and newspapers.
