Footbridge at Ullevaal stadium, Norway

EFLA, in collaboration with Brownlie Ernst and Marks Architects, has carried out the tender design of a new foot- and cycling bridge at the Ullevaal Stadium in Oslo.


The project also involves the design of a new layout of footways and roads, drainage and lighting systems, a landscaping scheme, new configuration of electrical and communications cabling in the area, geotechnical design, environmental studies and the auditing of existing nearby buildings.

The project's objective

The main objective of the project is to improve traffic safety and capacity of the pedestrians and cycling network in this part of Oslo, i.e. at the intersection of the Ring 3 motorway and Sognsveien road. The new bridge that has been designed crosses both roads and replaces temporary bridges built in 1990. These bridges no longer meet the requirements of pedestrians and cyclists in the area.

Traffic is heavy in the area and the intersection area contains a large amount of ground cables and pipelines. The needs of neighbouring facilities, such as Ullevaal Stadium, the Norwegian Geotechnical Institution and Blindern High School, must be taken into consideration during the construction phase. A detailed construction phasing plan has been drawn up as part of the work, to minimize the negative effect on nearby businesses, road users and pedestrians.

The construction work was set to commence in the fall of 2017. This is the largest of EFLA's projects for the Norwegian Road Authorities to date.

Details of the new bridge

  • Steel box girder bridge with plastic EPS ramps, founded on piles (up to 50 m long)
  • Bridge length = 290 m in 18 spans, length of ramps = 116 m
  • Total bridge width = 7.2 m, free width (footway + cycleway) = 6.0 m
  • Two main spans, one crossing Ring 3 = 37.5 m and the other crossing Sognsveien = 27.5 m

Environmental issues

EFLA partnered with seasoned bridge architects, Brownlie Ernst and Marks (BEaM), www.beandm.co, for the bridge design.

The landscape design was conducted by EFLA, focusing on the interaction of the project's different architectural elements.

Environmental and geotechnical field investigations were a part of the project's scope, as well as the specification of a protocol for the treatment of contaminated soil and minerals.
