(a) All parts of entrance and exit accesses on highway right-of-way shall be confined within the applicant's property frontage wherever possible.
(b) In all cases, curb return radii shall be confined to the applicant's property frontage wherever possible and shall not be less than 10 feet.
(c) Drainage in highway side ditches shall not be altered or impeded when drainage structures are required. The access slope shall be constructed to drain away from the highway. The approach side slopes shall conform to the latest safety standards. The sizes of openings and other design features shall be as directed by WYDOT, and the applicant shall pay the cost. Variation of the profile may be submitted for approval.
(d) WYDOT may authorize or require changes in design limits necessary to preserve the normal and safe movement of traffic or to permit reasonable access. After considering the type, speed, and volume of highway and access driveway traffic, the district engineer may require larger curb return radii than the minimum described in these rules and regulations.
(e) Two or more accesses entering a highway from a single commercial or residential establishment shall be justified to WYDOT's satisfaction and shall require a Traffic Impact Study.
(f) Landowners of adjacent property may be asked or may want to construct a joint access to serve both properties. All parties involved shall sign the access application permit except as described in following Section 14(g). A written mutual agreement, signed by all parties involved, shall accompany the application form. All requirements of these rules and regulations shall be met except that the side clearance restriction (Section 14 [b]) shall not apply. If either applicant violates any requirement of these rules and regulations, the joint access shall be removed by the applicants or WYDOT with the applicants paying for removal.
(g) If an easement is involved, a copy of the easement shall be included with the access application. A landowner signature may not be required for applications pertaining to easements.
(h) The applicant shall pave all major accesses. All other accesses that generate 50 trip ends or more per day shall be paved, or as stipulated in the permit.
(i) Access to interstate highways shall be permitted at interchanges only.
