[narrator] Part
of the huge project would involve laying
a section of highway higher than the original, flattening out
the existing terrain to make for
a much smoother ride. Using a retaining
or a gravity wall to hold the raised roadway
in place. [Joshua] A gravity wall
was chosen for
this particular location because the cheapest way
to do it is with a mechanically
stabilized dirt wall

[narrator] Part of the huge project
00:00:02.599 --> 00:00:04.799
would involve laying a section of highway
00:00:04.799 --> 00:00:06.599
higher than the original,
00:00:06.599 --> 00:00:08.533
flattening out the existing terrain
00:00:08.599 --> 00:00:11.733
to make for a much smoother ride.
00:00:11.799 --> 00:00:14.004
Using a retaining or a gravity wall
00:00:14.004 --> 00:00:17.633
to hold the raised roadway in place.
00:00:17.699 --> 00:00:21.000
[Joshua] A gravity wall was chosen for this particular location
00:00:21.000 --> 00:00:22.000
because the cheapest way to do it
00:00:22.000 --> 00:00:24.699
is with a mechanically stabilized dirt wall.
