Ambitions

● NTP 2018-2029

– E39 will be improved and ferryfree

– Progress planned in accordance with financialplanning and technological development

● NTP 2022-2033

– ?

● The route, from Kristiansand to Trondheim, is approximately 1100 km long. It runs through six counties, and the cities of Stavanger, Bergen, Ålesund and Molde. Travel time today is 21 hours, and seven different ferry connections. The aim is to create an improved E39, which will reduce travel time by half. The route will be almost 50 kilometres shorter.

Alternative solutions for the large fjord crossings

• Suspension bridge• Floating bridge (combined with

suspension/cable-stayed bridges)• Submerged floating tube bridge

(floating tunnel)• Immersed tunnel/

subsea rock tunnel • Frequent ferries

Kristiansand - Stavanger

● Statens vegvesen and Nye veier are two parts planning E39 south ofStavanger

● Existing road approx. 130 km + ferry

● Distance:

1. Bokn – Stord: 69 km

2. Stord: 7 km

3. Stord-Os: 52 km

● We are underway with the central government zoning plan in the south. In the north we have axept for crossing the Langenuenfjord in south.

● Planning time: 5 yearsConstruction start: To be decided through NTP 2022-2034

• Feasibility study through 2020

• End anchored or side anchoredfloating bridge or a best fitcombination of those.

● Risk asessment, Ship collission

• Scenario evaluations

• Mitigating actions and action effects

• Uncontrollable ship scenario

• Dimensioning strategy ship impactenergy

● Geological conditions nearly completed

Status and Progress, summary

E39 Bergen - Ålesund

01.11.2018

● E39 Sulafjorden, E39 Vartdalsfjorden og E39 Halsafjorden– Development of new technology– One project organisation for all

three crossings

● E39 Romsdalsfjorden– Well known technology– Sub-sea road-tunnel– Suspension bridge with main

span 1625 m

E39 Sulafjorden – preliminary loads

● Wind (10 min average)

● Climat models are very close to measurements

● Big loads make it one of the most complicatedfjord crossings on the E39

E39 Sulafjorden – schedule

● Contracts for the next stages is about to be signed

E39 Romsdalsfjorden

● Concept for new E39 Ålesund-Molde and thecrossing of Romsdalsfjorden is decided by The Ministry of Transport i 2014

● New considerations for all projects to newNational Transport Plan 2022-2033– Mission: Reduce cost or increase benefit

● Three main alternatives– Varieties of the accepted concept– Alternativ route (Romsdalsaksen)– High frequency ferries

● Alternativ route includes 3 km floating bridge– Assessment will be based on climat loads

from Bjørnafjorden

Molde

Ålesund

• Technologically feasible

• Feasible from a planning perspective

• Large positive Socio-Economic impact

• Financially challenging

Development strategy

Prefered solution on the following crossings (known technology, butstreched):

● Boknafjorden

● Romsdalsfjorden

● Development of new technology and more knowledge– Five highly challenging fjord crossings

– Looking at offshore methodology for technology development and qualification

– Studying wind, wave and current conditions

● Building competenceMore than 50 PhDs from the Norwegian University of Science and Technology (NTNU), Chalmers, the University of Stavanger (UiS) and others (including postdocs)

● Funding– Development costs: Requires funds to be allocated at an earlier stage than for traditional road

projects

● Design and Building– Contracting practice

Development strategy

Example of possible funding plan for the project
