The county of Agder has decided to build a stretch of road to improve traffic flow and safety between the municipalities of Neskilen and Heftingsdalen, on the outskirts of Arendal. The municipality wanted to separate the flow of traffic between the port, where a new battery factory is due to be built, and the coastal road, which is used by tourists.
This new departmental road includes a 300-metre tunnel, the project management for which was entrusted to SYSTRA, to be bored under the Hesthagfjellet hill.
To cut through the hard rock, the tunnel will be built using traditional methods, following plans produced entirely using a centralised BIM model. SYSTRA will be responsible for modelling the rock structure and designing the tunnel, access, electrical systems, drainage and environmental analysis with the aim of minimising CO2 emissions during construction.

This is a significant strategic win for SYSTRA. Firstly, it marks our first contract with this public client, offering the opportunity to establish a fruitful, long-lasting relationship with a major client that has several large projects in their pipeline for the coming years. Secondly, the project’s environmental and digital requirements align perfectly with SYSTRA’s strategy.
LARS CHRISTIAN HANSTEEN, PROJECT MANAGER, SYSTRA


We are delighted that the County of Agder has appointed SYSTRA to this assignment. This award is the result of exceptional teamwork, established since the tender phase and sustained throughout the execution of the task. This project will enhance our Norwaegian references portfolio, providing us the opportunity to further demonstrate our capabilities and expertise in upcoming competitions, strengthening therefore SYSTRA position on the Norwegian market.

The route of this new section of road links up with the new E18 motorway currently being built on the south Norwegian coast, a project in which SYSTRA is already involved with the doubling of the Grenland bridge, some fifty kilometres from Arendal.
