NORWAY'S western coast is dwelling to some of the nigh dramatic landscapes on earth.
Carved past times glaciers throughout the ages, some of these fjords stretch for 200 kilometres inland too are over a kilometre deep.

The electrical flow convoluted go route through too unopen to this terrain takes you lot along Norway’s 1,100 kilometre, 683 mile, E39 highway - a route amongst a full journeying fourth dimension of 21 hours.

Now, the Norwegian regime are working to improve access to services too residential too labour markets across the country’s western regions past times embarking on the largest infrastructure projection inwards the nation’s history.

The E39 runs between, Kristiansand inwards the far due south of the province too Trondheim inwards the north. The route navigates its agency across the fjord network too features no fewer than 7 ferry crossings.

The novel coastal highway projection aims to eliminate the take for ferry services altogether past times edifice a serial of bridges too tunnels across, through too nether the landscape.

With many of the fjords along the route existence likewise broad or likewise deep for conventional infrastructure to cross, innovative novel solutions are existence investigated past times the Norwegian Public Roads Administration.

Rogfast is the showtime inwards a serial of crossings that volition link the E39, connecting Stavanger too Haugesund via a 27 kilometre, xvi mile nether body of body of water tunnel.

This construction volition accomplish depths of upward to 390 metres below body of body of water level, making it the deepest equally good equally the longest undersea route tunnel inwards the world.

The Rogfast projection volition inwards fact consist of 2 tunnels connected every 250 metres amongst emergency exits. Each tunnel volition make got a lay-by at 500 metre intervals, along amongst telephone too surveillance cameras along the route.

The tunnel volition also characteristic a mid-route intersection amongst the isle municipality of Kvitsøy creating an undersea tunnel junction too connecting the isle amongst the Norwegian mainland.

With go begun inwards 2018, this chemical ingredient of the projection is laid to go completed past times 2026 at a toll of USD $2BN.
While the Rogfast industrial plant are already underway, the scale of another fjords is presenting the projection squad amongst extreme engineering challenges.
Bjornafjord - located to the due south of Bergen - stands five kilometres wide, too reaches depths of 600 metres.

To cross this challenging stretch of water, a proposal has been compass frontward for a floating bridge, anchored to the shore at both ends.

The Sulafjord crossing has seen 2 possible solutions compass forward.
The showtime is for a 3 tower interruption bridge, amongst 2 of the bridges’ towers anchored on reason too the tertiary fundamental tower anchored to the seafloor, some 400 metres below the H2O line.

An option proposal for a “submerged floating tunnel” would meet 2 interconnected tubes running following tethered to the seabed using high forcefulness cables.

Crossing the Romsdalsfjord volition require a xvi kilometre undersea tunnel, much similar the Rogfast project, from Alesund to Midsund - followed past times a 2 kilometre interruption duet connecting onto Molde....MUCH MORE
