Until the 1920s, Tajrish and neighboring Shemiranat were a collection of small villages along Capital’s border. The area was relatively disconnected from Tehran’s urban with the exception of Old Shemiran Road, currently known as Shariati Avenue.
With the construction of Pahlavi Road (now named Valiasr Street) in 1930s and Modarres Highway, then known as Shahanshahi Boulevard, the Northern suburbs became highly accessible from downtown and rapid extension became possible.
