The project's objective

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

The project's primary goal is to significantly enhance traffic safety and capacity for pedestrians and cyclists in this part of Oslo, particularly at the intersection of the Ring 3 motorway and Sognsveien road. The new bridge, designed to span both roads, will replace the temporary bridges constructed in 1990, which no longer meet the area's needs.

Given the heavy traffic in the area and the significant number of ground cables and pipelines at the intersection, it's crucial to consider the needs of nearby facilities, such as Ullevaal Stadium, the Norwegian Geotechnical Institution, and Blindern High School, during the construction phase. A detailed construction phasing plan has been developed to minimize disruption to nearby businesses, road users, and pedestrians, demonstrating our respect for their needs.

Construction was set to commence in the fall of 2017. This is the largest project of EFLA 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
Roads.

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.

EFLA's role

  • Project management and coordination with third parties
  • Bridge design, concept study and tender design
  • Adjoining structures such as retaining walls and sound barriers

  • A new network of foot- and cycleways in the area
  • Street and bridge lighting schemes
  • Ground cabling
  • Drainage and surface water treatment
  • Landscape design
  • Construction phase planning
  • 3D coordination model
  • Tender specifications
  • Field research
  • Construction auditing

The project´s long term benefits

Improved traffic safety and reduced commute time for pedestrians in this part of Oslo.
