During National Volunteer Week, ADOT is extending thanks to all Adopt a Highway volunteers for removing litter from alongside the state highway system that connects Arizona communities. However, it is more than volunteering for many. Loved ones, veterans, beloved pets â our personal heroes are honored when volunteers gather to beautify adopted miles. Family and friends reunite and remember. Gila County sheriff deputies have done just that for the past 26 years on State Route 188 at mile marker 256. On April 9, Sheriff J. Adam Shepherd, Chief Deputy Mike Johnson, Lt. Virgil Dodd, Undersheriff Matt Binney and Major Justin Solberg were recognized along with other deputy team members who could not be present for their longtime volunteer service.
