Maintenance
The primary purpose of any roadway maintenance is to keep the transportation facilities
in safe operating condition and to protect the public's investment. The entire
transportation program is affected by the degree of efficiency of the maintenance work
performed on the system. The organizational structure for road maintenance is based on
a route's designation.
Routes on the state road system are the direct responsibility of IDOT. District
Maintenance Engineers formulate the annual maintenance work program. The annual
program is funded using monies appropriated for both routine and special maintenance.
Some examples of state maintenance activities include: general maintenance, winter
maintenance, bridge maintenance and roadside facilities.
The county is responsible for maintaining routes on the county road system.
Roads carrying a BIA designation are eligible for maintenance through the Area Roads
Engineer and Agency Roads Engineer. However, maintenance and construction of roads
with a Tribal designation is solely the Tribe's responsibility. The Tribe's options include:
the establishment of a BIA road maintenance program for the Community, the
establishment of a tribal highway department through a road maintenance contract with
the BIA as permitted under Public Law 93-638, or the establishment of a maintenance
agreement with a local governmental entity or construction firm. These options may be
limited by the amount of hnds available to the Tribe and the amount they choose to
allocate to roadway maintenance.
It is recommended that the Tribe develop a road maintenance program. This program
will allow the Tribe to track and better budget for road maintenance. Information in
regard to deferred maintenance will also be tracked thereby allowing the Tribe to better
understand long range costs to maintaining the road inventory. The BJA Midwest
Regional Office is able to assist the Tribe with the development of such a program.
Network Deficiencies
Network deficiencies deal with roadway surface characteristics such as rutting, cracking,
corrugation, bleeding, gravel loss, grade depression and performance during inclement
weather.
Rutting is a surface condition familiar to all dnvers. It is the result of inadequate
drainage and may cause damage to the road base if the condition is severe. It should be
