Wyo. Stat. § 24-6-108: Property rights of abutting residents.

No access facility shall be constructed without providing for the property rights of residents whose homes or places of business are now located on or abut the said proposed access facility. In all such cases, provisions shall be made to afford said residents access to said facility within five hundred (500) feet of their homes or places of business; or in the alternative, and at the option of the proper highway authorities, service roads shall be built so as to afford said residents a convenient route to the nearest city, town or village adjoining them.
