It shall be the duty of the several boards of supervisors to properly maintain all local system roads in their respective counties after construction of any such roads under this chapter. It shall be the duty of the State Aid Engineer and his assistants to make annual maintenance inspections of completed projects, and such other periodic maintenance inspections as the State Aid Engineer shall deem necessary. If essential maintenance is not properly and regularly carried on, in the opinion of the State Aid Engineer, then notice thereof shall be given in writing to the board in default, and if such maintenance is not done and continued within sixty (60) days from date of such notice, then, and in such event, the State Aid Engineer may proceed to have done the necessary maintenance and repair work on such road and charge the same to any funds allocated to such county under the provisions of the Local System Road Program. If such failure to maintain continues, then such county shall be no longer eligible for monies under the Local System Road Program until proper maintenance is resumed by it, and notice of such withdrawal of local system road funds shall be duly given the State Treasurer; however, such ineligibility shall not affect payment under the Local System Road Program of progress or final estimates on contracts awarded before notice of such ineligibility.

Local system roads that have been hard surfaced through the use of local system road funds shall be eligible for local system road funds to provide one or more seal courses, as required. Local system roads in which the grading and drainage structures were constructed under the Local System Road Program and which have been subsequently hard surfaced by the county through the use of county funds under the supervision of the county engineer shall likewise be eligible for local system road funds to provide one or more seal courses as required, provided that the hard surfacing and underlying base were constructed in accordance with the then prevailing local system road standards and specifications. The county shall furnish the State Aid Engineer with sufficient engineering data, including borings and tests, if necessary, to substantiate the required thickness and quality of the base and surfacing. The correction of base defects and pavement breaks may be made part of the plans and contract documents for each sealing project.

Local system roads that were constructed in accordance with the then prevailing local system road standards and specifications shall be eligible for local system road funds for maintenance, repair and reconstruction, subject to the prior written approval of such work by the State Aid Engineer and subject to the work being completed in accordance with the prior written approval.
