The Right of Way Section of the Idaho Transportation Department is responsible for the acquisition of all property required for highway construction, material sources and maintenance shed sites. The Section is also responsible for the oversight of all Local Public Agencies acquiring property, who utilize federal funding for highway purposes. The acquisition of right of way follows the planning and design phases of the highway development process and is one of the final phases prior to the actual award of the construction contract.
The cache is NOT available from the highway - you can only access it from Pioneer Road. There is no parking at GZ so just go down the road a little and find a safe turn-out. Although I find very little traffic along Pioneer Road, I do not recommend this one for kids because of the lack of a sidewalk.
