Finnevik Bridge

Finnevik Bridge is located in southern Espoo and it connects Matinkylä and Finnoo residential areas. Total length of the bridge is 365 m and it is the longest bridge in Espoo. The bridge serves public transport network when new metro route opens in the autumn 2016. The area is developing in the near future and Finnoo will grow into a considerable large residential area. Finnevik bridge is remarkable visible landmark of the new area and is essential way to local residents.

In the beginning of the planning process different ideas and drafts about the bridge and it’s lighting came up at the workshop where participated several specialist from different planning fields. The team decided that lighting is important part of the bridge design from the very beginning. Finally our innovative design team created solution with high-quality and yet cost and CO2 efficient.

The lighting is designed in the spirit of four seasons. Façade lighting repeats colors of the ongoing season. In addition lighting is programmed for special festive days according to the calendar year as well as the special days of the city of Espoo. The most used colors at festive days at winter time are blue, violet and turquoise.  Orange and red will be seen at falltime. Lights turns on and off at the same time as streetlights.

Sustainability was one of the main planning principle through the hole process. The carbon footprint of the construction work comes mainly from material production which results that cost efficiency and common solutions are usually the most ecological possible. According to this principle the bridge was planned as a ordinary concrete beam bridge but with special architectural twist. Horizontally curved street alignment made possible to accentuate the shape of the bridge, not only beneath the bridge but also when you are crossing the bridge. Continuous curved shape was achieved with designing the edge beam and the bottom deck of bridge and with longitudinal metal lath. The metal lath is also a part of the lighting. More over three middle groups of illuminated askew columns makes an interesting detail.

A significant birds nesting environment is located in the south of the bridge. Therefore the façade lighting is turned off during the hole nesting time from 1st of April until 31st of July. Façade lighting is turned on in the evening of the Espoo day which is annually last Saturday of the August.

RGB luminaires (manufacturer SavLed) are installed behind the steel framed sheets. DMX control unit makes it easy to change lighting if desired when the area develops. Street lighting poles are specially designed for Finnoo area. Luminaires are modern LED-luminaires from AEC.
