After the renovation of the A4 roundabout, the Municipality of Bergamo completes the construction of the roundabout with fountain at the intersection with via Carnovaliinaugurated tonight with the lighting. The roundabout is 47 meters in diameter and has two lanes; pedestrian crossings – equipped with backlit signs with flashing buoys and a lighting system – have been provided at each arm of the roundabout, with the exception of the one along the motorway. In order to build the roundabout, the Municipality also intervened on the Punto Blu on via Autostrada, modifying the layout of the entrance and redesigning the perimeter of the de-paved spaces. In the center of the new roundabout the fountain was built – 15 meters in diameter, with 40 different jets of water –in turn surrounded by a green ring in its outermost part.
The water
Therefore, to make the operation of the fountain as sustainable as possible, the hydraulic system was designed to work with very high efficiency motors and latest generation lighting systems. Suffice it to say that the large flow rate of circulating water, of approximately 180 l/s, is moved by probably consuming as much as an electric-powered small car, while the 46 RGBW LED spotlights, in addition to the 80 meters of RGB LED strip, consume little overall. more than two halogen household light bulbs. Not only that: to minimize maintenance costs, the fountain was designed for total automation that can also be controlled remotely; Furthermore, municipal staff have been specially trained for management and the “in house” maintenance of this hydraulic engineering prototype.
The numbers of the fountain
15 metres: the diameter of the fountain, for a height of the reservoir of 0.5 metres
40: the different jets arranged in a circular crown + 1 in the center of the tank
46: the RGBW LED spotlights for the fountain lighting; 80 meters of RGB LED strips (total 0.7 kW), manageable with the app
4: very high efficiency electric pumps controlled electronically with a specific application for the management of recirculation and water treatment
200: m3 of water consumption per year (three changes per year); electricity approximately 40,000 Kwh/year
Trees
Via the motorway it will also be a tree-lined avenue, with cycle paths bordering both sides, and owned by the municipality: this will change the main access to the city of Bergamo for all those arriving in Bergamo from the A4 and the interurban axis by the end of next year. The idea of an urban access road and no longer a motorway connection ramp will therefore not be just a suggestion – the one that Peter Fink designed in 2016 with his summer school of the Masters of Landscape, an initiative desired with the ‘then environmental councilor Leyla Ciagà –, but it will be a reality by the end of 2025.
As part of the agreement already approved by the City Council of the Integrated Highway Plan, the Administration has identified the transformation of the highway – in the stretch between the intersection with Via Carnovali to the roundabout near the Coop – into an urban avenue as the public planned for the benefit of the city.
