E39 road European route E39 is a north–south trans-European corridor running along the western coast of Norway and across Jutland to northern Denmark. The route links major Norwegian urban centres, fjord crossings and maritime links with Danish motorways, integrating with international networks such as the European route system, Trans-European Transport Network priorities and regional port systems. E39 connects cultural, industrial and energy hubs including Bergen, Trondheim, Stavanger, Kristiansand, Aarhus and Aalborg through a mixture of motorway, national highway and ferry segments.

Route description

E39 runs roughly 1,226 km from the Bergen region in Vestland county through Vestland, Rogaland, Agder, Vestfold og Telemark and Trøndelag counties in Norway before terminating via ferry and road connections to Aalborg in North Jutland, Denmark. The corridor traverses the North Sea coastal margin, fjords such as the Sognefjord, Hardangerfjord and Trondheimsfjord, and urban agglomerations including Bergen, Stavanger, Kristiansand, Tromsø (note: access linkages), Trondheim and Aalborg. Segments alternate between dual-carriageway motorway standard around conurbations and single-carriageway national road across rural stretches. Key interchanges link E39 with European routes E6, E18 and regional arteries near ports like Bergen Port, Stavanger Port and Aalborg Havn.

History

The present alignment developed from 20th-century national roads and ferry links established in the 1950s–1970s to support postwar reconstruction, maritime industry and petroleum expansion after discoveries in the North Sea oil fields. During the 1990s and 2000s, upgrades reflected priorities from the European Union transport policy and Norwegian national plans such as the National Transport Plan adopted by the Stortinget. Historic ferry routes connected municipalities like Molde, Ålesund, Florø and Bergen; over time many crossings were replaced by bridges and tunnels such as the Stord Bridge and Karmøy Tunnel. Engineering milestones parallel major infrastructure projects commissioned by agencies including Statens vegvesen and regional authorities in Vestland and Trøndelag.

Infrastructure and construction

Infrastructure along the corridor comprises long-span suspension and box-girder bridges, subsea tunnels, upgraded motorway sections and port interfaces. Notable structures include subsea solutions like the Bømlafjord Tunnel and the planned Hordfast link, as well as bridge complexes around Stord and Haugesund. Construction methods combine immersed tubes, bored tunnels with TBMs and driven rock tunnels using drill-and-blast in hard Norwegian gneiss. Materials and design standards reference European codes such as those from the European Committee for Standardization; contractors have included major engineering firms from Norway and abroad, often in public–private partnership procurement models influenced by Norwegian procurement law administered via Statens kartverk and municipal planning authorities.

Operations and traffic

Traffic on E39 exhibits strong seasonality tied to tourism, ferry timetables and petroleum-industry logistics serving platforms in the North Sea oil fields and supply bases in Stavanger and Kristiansund. Average daily traffic ranges from urban motorway levels in Bergen to low-flow rural segments on fjord peninsulas. Tolling regimes, automated toll stations and congestion pricing around urban bypasses are managed by concessionaires and municipal bodies; examples include toll rings near Stavanger and Bergen. Freight movements comprise container shipments via ports, heavy goods vehicles servicing aquaculture centres in Møre og Romsdal and timber exports from inland regions. Safety initiatives reflect collaboration among Norwegian Public Roads Administration, county police forces and rescue services.

Future developments and planned projects

Major planned projects aim to reduce ferry dependence by replacing crossings with bridges and subsea tunnels, exemplified by proposals such as the Hordfast project between Bergen and Stord and the long-term vision for a fixed link across the Sognefjord. National Transport Plan funding cycles and local referenda influence timing; ambitions align with decarbonisation objectives promoted by Norwegian Environment Agency and EU climate targets. Pilot deployments of electric vehicle charging corridors, V2X infrastructure and intelligent transport systems are advancing with partners including Statkraft and automotive industry stakeholders. Cross-border coordination with Danish authorities focuses on ferry integration with the European route E45 network and port connections to Frederikshavn and Aalborg.

Major junctions and ferry/bridge crossings

Key junctions connect with E6 at Trondheim-area interchanges, E18 near Kristiansand, and regional arteries at Stavanger and Bergen. Principal ferry or fixed crossings historically and currently include services linking BergenStord, crossings at Sognefjord and the Hardanger Bridge link near Odda; subsea tunnels like the Bømlafjord Tunnel and planned Hordfast components are central. Intermodal transfers occur at ports including Bergen Port, Stavanger Port, Kristiansand Port and Aalborg Havn, with rail connections available via Bergensbanen, Dovre Line and feeder services to regional stations.

Economic and environmental impact

E39 underpins coastal economies by connecting fisheries hubs, aquaculture sites in Møre og Romsdal, petroleum supply chains in Rogaland, and manufacturing clusters in Vestland and Trøndelag. Improved links reduce transport time for exports to markets served by ports such as Aalborg and Bergen Port and support tourism to cultural sites like Bryggen (Bergen) and outdoor destinations in Lofoten (via connecting routes). Environmental considerations include impacts on fjord ecosystems, greenhouse gas emissions mitigation through EV corridors, and habitat fragmentation concerns addressed in environmental impact assessments submitted to the Norwegian Environment Agency and county municipalities. Projects balance economic benefits against preservation of UNESCO-listed and nationally protected areas.
