Turnkey Contract E18 Rugtvedt-Dørdal

Antall eller omfang

The contract work E18 Rugtvedt-Dørdal comprises engineering design, construction and any operations and maintenance of approximately 16,8 km of new 4 land national road from Rugtvedt to Dørdal in addition to connections to the existing E18. Most of the new stretch of road will be lain in a new route outside of the existing road and built-up area. At Rugtvedt and from Langrønningen to Bakkevannet, the road goes in approximately the same route as the current E18. The works include individual alterations and expansions of adjoining roads.The zoning plan contains plans for the construction of 10 bridges in-line with lengths from approximately 25 metres up to approx. 455 metres, and 6 overpasses. Furthermore, 3 environmental tunnels are planned along with a number of culverts.Below is a list of the provided sizes of the primary structures:Rugtvedt tunnel (environmental tunnel) 122 m;Vardås tunnel (environmental tunnel) 70 m;Langrønning tunnel (environmental tunnel) 60 m;Hegna bridge 47 m;Hydal bridge 214 m;Vinterdal bridge 250 m;Tinderholt bridge 85 m;Mørkekjerr bridge 215 m;Stemmen bridge 455 m;Svartholt bridge 195 m;Rønholtdal bridge 245 m;Sprangfoss bridge 90 m;Hanfang bridge 25 m.2 large crossing areas are planned with exits and entries and connections to the local road network. The crossing at Rugtvedt is an expansion of the current traffic solution, where a new 4 lane E188 will be placed in a new environmental tunnel. An oval roundabout is planned on the top of the tunnel in order to manage the traffic from the ramps and local road system. The crossing at Langrønningen is planned as a standard route crossing with a roundabout on each side of the primary road. In connection with the crossing there are zones areas for both 24 hour resting places for heavy transport, service facilities and resting place.The majority of the installation activity will take place a good distance from the current E18. The Rugtvedt area and the area from Dørdal toward Bakkevannet require special measures to ensure safe and good traffic deviation during the construction period. A diversion road is needed on the area from the current crossing at Dørdal and up until Bakkevannet, which will be used when the new E18 is being blasted in Hanfangåsen. This involves comprehensive blasting works.Mass transport on the public road network should be avoided.There are separate plant areas in the zoning plan.The operations and maintenance period of E18 Rugtvedt-Dørdal is planned to be 20 years.
