the western coast of norway
[8]
is home to some of the most dramatic
[10]
landscapes on earth carved by glaciers
[17]
throughout the ages
[18]
some of these fuels stretch for 200
[21]
kilometers inland
[23]
and are over a kilometer deep
[27]
the current convoluted travel routes
[29]
through and around this terrain
[31]
takes you along norway's 1100 kilometer
[35]
683 mile e39 highway
[38]
a road with a total journey time of 21
[42]
hours
[44]
now the norwegian government are working
[46]
to improve access to services
[48]
and residential and labor markets across
[51]
the country's western regions
[53]
by embarking on the largest
[55]
infrastructure projects in the nation's
[57]
history
[57]
[Music]
[70]
norway's e39 highway runs between
[73]
christensen in the far south of the
[75]
country and trondheim in the north
[78]
the route navigates its way across the
[80]
fjord network
[82]
and features no fewer than seven ferry
[84]
crossings
[86]
the new coastal highway project aims to
[88]
eliminate the need for ferry services
[90]
all together
[91]
by building a series of bridges and
[93]
tunnels across
[95]
through and under the landscape
[98]
with many of the fields along the route
[100]
being too wide or too
[102]
deep for conventional infrastructure to
[104]
cross
[105]
innovative new solutions are being
[107]
investigated by the norwegian public
[109]
roads administration
[112]
rugfast is the first in a series of
[114]
crossings that will link the e39
[116]
connecting stavania and halkerson via a
[119]
27 kilometer
[120]
16 mile undersea tunnel
[124]
this structure will reach depths of up
[125]
to 390 meters below
[128]
sea level making it the deepest as well
[130]
as the longest undersea road tunnel
[132]
in the world the roguefast projects will
[136]
in fact consist of
[137]
two tunnels connected every 250 meters
[140]
with emergency exits
[143]
each tunnel will have a lay-by at 500
[145]
meter intervals
[146]
along with telephone and surveillance
[148]
cameras along the route
[151]
the tunnel will also feature a mid-route
[153]
intersection
[154]
with the island municipality of kavitsoy
[157]
creating an undersea
[158]
tunnel junction and connecting the
[160]
island with the norwegian mainland
[162]
[Music]
[164]
with work began in 2018 this element of
[167]
the project is set to be completed by
[169]
2026
[171]
at a cost of 2 billion us dollars
[175]
while the rockfast works are already
[177]
underway
[178]
the scale of some other fields is
[180]
presenting the project team
[182]
with extreme engineering challenges
[188]
burner fjord located to the south of
[190]
bergen
[191]
stands five kilometers wide and reaches
[193]
depths of 600 meters
[196]
[Music]
[197]
to cross this challenging stretch of
[199]
water a proposal has been put forward
[201]
for a floating bridge
[203]
anchored to the shore at both ends
[207]
the sula fjord crossing has seen two
[209]
possible solutions put forward
[212]
the first is for a three tower
[214]
suspension bridge
[216]
with two of the bridges towers anchored
[218]
on land and the third
[219]
central tower anchored to the sea floor
[222]
some 400 metres below the waterline
[226]
an alternative proposal for a submerged
[228]
floating tunnel
[229]
would see two interconnected tubes
[232]
running side by side
[233]
tethered to the seabed using high
[235]
strength cables
[237]
crossing the rumdel's fjord will require
[240]
a 16 kilometer undersea tunnel
[242]
much like the roguefast project from
[244]
olsond to midcent
[246]
followed by a two kilometer suspension
[248]
bridge connecting onto moulder
[252]
by far the most complex and ambitious of
[255]
all the coastal highway crossings
[257]
is that at songnifield also known
[260]
as the king of the fjords
[262]
[Music]
[263]
norway's largest and deepest fjord is
[266]
over 3.7 kilometers wide
[268]
and an incredible 1.3 kilometers deep
[271]
at its lowest point while these extreme
[275]
distances
[275]
pose their own challenges engineers must
[278]
also account for the high number of
[280]
ships that enter the fjord on a regular
[282]
basis
[284]
any crossing must allow for a clear
[286]
shipping lane
[287]
that is at least 400 meters wide with 70
[290]
meters clearance
[291]
above the water's surface and at least
[294]
20 meters clearance
[295]
into the depths to deliver this
[299]
the project team are considering
[301]
numerous different types of crossing for
[303]
this fjord
[304]
the first is a traditional suspension
[306]
bridge
[308]
with a 3700 meter crossing such a
[311]
structure would be almost double the
[313]
length of the world's current longest
[315]
bridge
[315]
and would require support towers at
[317]
least 450 meters tall
[320]
significantly eclipsing the 343 meter
[323]
tall
[324]
allow viaduct in france to become the
[326]
world's
[327]
tallest bridge structure a floating
[330]
bridge
[331]
is also being considered however
[334]
this structure would need to raise to
[336]
allow ships to pass
[338]
and achieving such a feature in a bridge
[340]
that is only anchored to each shoreline
[342]
poses considerable engineering
[344]
challenges that are yet to be overcome
[348]
in a similar proposal to that found at
[350]
sula fjord
[352]
a submerged floating tunnel is also
[354]
being considered
[356]
this proposal would differ slightly to
[358]
its counterpart due to the extreme depth
[360]
of songfield
[362]
rather than being tethered to the seabed
[364]
the tunnels would be suspended
[366]
from floating pontoons that would allow
[368]
ships to pass overhead
[370]
a hybrid proposal is also being
[373]
considered
[374]
combining a floating pontoon bridge with
[376]
a portion of submerged floating tunnel
[379]
that allows ships to pass whilst
[382]
fixed bridges transferring into fixed
[384]
tunnels is not an uncommon solution in
[387]
waterways with high shipping traffic
[389]
such as the link between denmark and
[391]
sweden and the extensive hong kong to
[393]
macau crossing
[395]
combining the two floating structures in
[397]
this way
[398]
would create the world's first example
[400]
of such a solution
[402]
finally a proposal for a multi-span
[406]
cable-stayed bridge is under review this
[408]
structure would feature
[410]
four floating pylons tethered to the sea
[412]
floor
[413]
rather like oil rigs with safety and
[416]
environmental considerations being of
[418]
the utmost importance
[420]
norway's vast coastal highway project is
[423]
set to become a new benchmark in
[425]
engineering capabilities
[426]
and a model for future infrastructure
[428]
projects around the world
