The Interstate Maintenance Program provides funding for resurfacing, restoring, rehabilitating, and reconstructing most routes on the Interstate System. The program is 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 off-peak hours. This in turn leads to higher costs for construction in urban areas compared to projects in rural areas.
The Region 1 2021-2024 STIP funding allocation for the Interstate Maintenance Program is $23,942,994.
