The Interstate Maintenance program provides funding for resurfacing, restoring, rehabilitating, and reconstructing most routes on the Interstate System. The program is very similar to the Preservation program; however, funds in the program must be spent on the interstate system. A significant portion of the Region’s Interstate Maintenance and Preservation projects are in urban areas where traffic conditions affect the hours available for construction and the mobilization of construction teams during offpeak hours. This in turn leads to higher costs for construction in urban areas compared to projects in rural areas.
Potential projects are identified by the Statewide Interstate Maintenance Program Manager in Salem based on interstate pavement conditions and needs statewide. Potential projects are then forwarded to the Regions to develop cost estimates.
