§ 115. Preparation of map showing proposed county road system. The
county superintendent of highways of each county shall prepare a map
showing a proposed county road system for such county to be constructed
with moneys from the county road fund, such system not to include a
state highway, except that a designated state highway not under state
maintenance may be included in such system and be improved by a county.
This map must be approved by the board of supervisors of such county
before it becomes effective; and when so approved it shall be filed in
the office of the county clerk and county superintendent. An existing
map of a county road system, however, may be approved by the board of
supervisors and, when approved by such superintendent, such action shall
be deemed a compliance with this article, when the map is filed as above
provided. Thereafter, except as otherwise provided by section one
hundred fourteen of this chapter, no road shall be constructed,
reconstructed or maintained with any such county road fund moneys except
the road set forth on such map, excepting, however, and notwithstanding
any of the provisions of this article, any highway enumerated in section
three hundred forty-one of this chapter that has been constructed or
improved under section one hundred and ninety-four or one hundred and
ninety-five, or under the general or special law governing the
construction or improvement of highways, that has been constructed or
improved as a state highway, may be maintained from such county road
fund moneys. Amendments to such map may from time to time be made by
such county superintendent and if approved by such board of supervisors
shall be filed in the office of the county clerk and county
superintendent. Construction in accordance with such map shall, subject
to the provisions of this chapter, proceed in such manner that any money
in the county road fund used in any one year shall be used so far as is
practicable to build or finish complete road units or projects as shown
on such map within such year and not to construct parts of units or
projects divided from each other.
