Marathon County Uniform Addressing
In February 2016, the Marathon County Board adopted a policy to implement a uniform addressing system.
The project was completed in November 2019, and resulted in changes to many street numbers and some road names throughout Marathon County.
Uniform addressing enables public agencies, especially emergency services, to provide the right service to the right place at the right time.
