2nd level of Sadr highway in Tehran was built in 2014 by Tehran Municipality. The projects lengths consists of more than 500 light masts. a special edition of Vaswa Midi projectors were installed in the light masts with a specific blue light spectrum and extreme narrow light distribution.
The idea of the lighting designer came from connecting the top part of the bridge to the bottom level which last had designed to have some linear blue lights (symbolising old rivers in Tehran) and to change the light mast to an architectural element.
