The Middle Ring Expressway



The Middle Ring Expressway, located at Suzhou Hi-Tech Zone, has transformed into the most brilliantly luminated municipal road in the city.

With a total investment of RMB 22 billion, the roadway was equipped with around 2,000 sets of OSRAM OLUX™ LED Spot H with 4000K color temperature. In addition, around 10,000 sets of OSRAM XTRA Liner DC were used to achieve different lighting effects by changing the high powered LEDs. The seamless lighting effects are operated by e:cue control systems, including Butler S2, LCE 2 and RDM Isolater that control around 10,000 sets of OSRAM XTRA Liner LEDs, which produce identical colors simultaneously.

Connecting 27 nearby areas, the Middle Ring Expressway is one of the most important transportation hubs in Suzhou city. This 112 km expressway consists of six lanes of two-way traffic, supporting speeds up to 80 km/h. Now outlined by fascinating lighting effects, drivers and passengers of this roadway can truly enjoy this exquisite journey. Traxon & e:cue is excited to be part of this outstanding project.
