adaptable to walkway construction.
Figure 1 shows a section of the south
jetty with the fishing walkway (US Army Engineer District, Charleston,
1975). The jetty walkway was constructed with asphalt pavement and extended
the 3,600-ft length of the south jetty. The walkway width was established at
8 ft so that trucks carrying materials and equipment could use the jetty
during construction and maintenance operations of the project. The large
voids between the 6-to 8-ton armor stone were filled with smaller leveling
stones and asphaltic concrete grout extending into the structure about 3 ft.
The grout was then capped with about a 4- to 6-in. layer of hot mix asphalt.
While this surface is somewhat flexible, rubble-mound structures tend to shift
under wave attack; therefore, frequent pavement maintenance may be required.
H o w e v e r , after over 4 years, the Murrells Inlet jetty walkway has needed only
minor repair.
Although the walkway at Murrells Inlet does not have safety handrails,
that addition might encourage more public use.
However, of all the publicly-
used coastal structures which have been constructed or modified by the Corps
of Engineers , only about one-fourth have been equipped with handrails. If
only one handrail is installed, generally it should be placed on the beach
side of the jetty structure to avoid impeding access to the deepwater inlet
side which is fished more extensively.
Fishing from the jetty walkway is
difficult due to the side slopes of the structure. As a result, fishermen
climb down nearer the waterline where they may be in danger from wave action
and slippery surfaces.
