PONTE ROMA BRIDGE, BOLZANO [I]
The Ponte Roma bridge, built in 1935, was adapted within the scope of comprehensive rebuilding in order to fulfil increased safety and mobility requirements.

Apart from static safety and rebuilding of the historical substance of the bridge, the lighting complex was also renewed.

The lighting systems manufactured by ewo require 5 type DS32 luminaires and provide a safe and energy-efficient illumination of the carriageway that also complies with standards.
