As the sixth bridge to cross the Han River, the 666-meter long bridge was put into use on March 29, 2012.

The six-lane bridge boasts a system of 15,000 LED lights that allow it to change color at night. And yes, it can it also breathes out fire and water.

A new symbol of Da Nang, the bridge has won international awards, notably the Lighting Design Awards 2014 that recognizes excellence in architectural lighting design

Time-lapse photographer Rufus Blackwell spent the last two months carrying a DJI Osmo handheld stabilized camera around Ho Chi Minh City. The three-minute video below was the result.

“The OSMO is a hand held gimble camera that keeps the shot amazingly steady even if you are shooting hand held,” Blackwell told Thanh Nien News.

“A completely new way of creating a moving time-lapse. This allows you so much latitude you can warp time. This was a highly experimental shoot.”

Blackwell won the 2014 Travel Photographer of the Year contest in the video category with a piece about the Kumbh Mela festival in India and the 100 million people that attended it.
