Promitto AS Supplies 55,000 Meters of LED Lighting for Stockholm’s E4 Bypass Project
Promitto Group AS Supplies 55,000 Meters of LED Lighting for the E4 Förbifart Stockholm Project
Promitto Group AS, in collaboration with Bravida Sweden, is proud to announce its participation in the E4 Förbifart Stockholm project by supplying an impressive 55,000 meters of LED lighting. This ambitious initiative is led by the Swedish Transport Administration (Trafikverket), which is constructing a new segment of the E4 road west of Stockholm, known as Bypass Stockholm.
The new 21-kilometer stretch includes extensive tunnel sections that traverse urban areas, connecting Stockholm from north to south. To preserve vital environmental and cultural values, approximately 18 of the 21 kilometers will be built underground, making the E4 Förbifart Stockholm one of the longest motorway tunnels in the world.
With the advanced technical systems being implemented in the E4 Förbifart Stockholm, the amount of technical equipment in Stockholm’s road infrastructure will double.
The E4 Bypass Stockholm features 21 kilometers of tunnels, which include two parallel service tunnels, ramps, and cross-tunnels.
The project’s total budget is estimated at 41.7 billion Swedish kronor (at 2021 price levels), according to the National Transport Infrastructure Plan for the period 2022-2033, with an expected completion date set for 2030.
Promitto Group AS is excited to contribute to this groundbreaking project, bringing innovative LED lighting solutions that enhance safety, efficiency, and sustainability in one of Sweden’s most significant infrastructure undertakings.
55.000 meters of LED-strip
In collaboration with Bravida Sweden, Promitto Group AS is supplying 55,000 meters of LED lighting for the service tunnels. Bravida has been entrusted with executing all installations related to the subcontracting work, including electrical supply, lighting, HVAC, and fixed fire extinguishing systems—covering planning, construction, production, delivery, installation, testing, maintenance, and commissioning.
The tunnel facility is divided into 33 operational areas, each requiring various types of lighting, encompassing a total of approximately 55,000 meters of tunnel piping. Within these areas, there is a parallel cable duct and an extensive system of escape routes where lighting will be installed. The chosen solution is a lighting system tailored to meet the specific needs of Trafikverket.
Promitto is delivering 55,000 meters of lighting, consisting of both LED strips and floodlights. Power cabinets will be strategically placed approximately every 150 meters throughout the tunnels. Promitto provides a complete solution with LED strips connected in segments of 3×50 meters, along with HighLite floodlights for the cabinet areas. All lighting will be powered by a single power supply, simplifying installation work and resulting in significant cost savings.
