The city of Tucson is starting several projects to improve the top layer of roadways in the next week.

The efforts are part of the city's five-year road repair program.

All of the work for road maintenance is paid for with a $100 million bond, which Tucson voters approved November 2012.

Road repair can range from total reconstruction, which means ripping up a bad road and repaving it, to treating just the surface of a good road to keep it in good shape for longer.

Crews will be applying sealants to the Five Point Intersection, a one-mile section of Roger Road between Oracle Road and First Avenue, and Drexel Road from Mission Road to the Santa Cruz River.

The sealants are used to fill small cracks to prevent them from getting bigger and turning into potholes.

Business and residential access will remain throughout the duration of the project.
