A survey from Port Orford south was commenced in December of 1917. A
line was located and staked ready for construction between Port Orford
and Hubbard Creek, eliminating steep grades and sharp curves on the
present road. A close preliminary line was run between Hubbard Creek and
Mussel Creek (Arizona Inn), a thorough study made of the conditions and
the following route recommended, which eliminates the excessive grades
and high summit of 1,100 feet of the present road. The location lies
between elevation 100 and 400, dropping into and crossing drainage as it
is met, following close to the beach until Brush Creek is reached, then
following up Brush Creek on the east side of Humbug Mountain until an
intersection with the present road is reached, straightening out present
road for about one mile, then following the coast between elevation 200
and 400, dropping into Mussel Creek.
The controlling points on this route are the slides which must be headed
to secure a stable roadbed. A twelve-foot roadbed has been proposed for
this project, with maximum six per cent grades and the construction even
for this narrow width is heavy as it will be necessary to bench out the
entire width of the roadbed on solid ground, the slopes being too steep
for fill to catch. Considerable bridging is required and a gravel
surface provided throughout the entire length to insure an all year
road, so the cost of even this narrow roadbed will be high.
A beach route located about ten feet above high tide has been proposed,
and, while this has the advantage of shorter distance and no rise and
fall, this route is not believed to be feasible because the underlying
rock is soft and disintegrates readily and is eroded by tidal action to
a considerable extent. The numerous slides at this elevation would also
make construction on this location inadvisable for a permanent road.
A reconnaissance was made between Mussel Creek and Gold Beach. After
leaving Mussel Creek, considerable development work is required to
attain standard grade, and but a small portion of the present road could
be used. Passing Euchre Creek, there will be utilized along Cedar Creek
a new section of road about eight miles in length which has been
recently graded by the County. If widened and the alignment corrected in
a few locations, this would afford a direct route to the Rogue River
where a ferry runs regularly. Between the river crossing and Gold Beach
there is a fair road requiring only straightening out and widening.
