Section Trans 231.04 - Commercial - ruralOn rural type highway cross section, driveways serving commercial or industrial establishments shall conform to the following:
(1) WIDTH OF DRIVE. No driveway except as hereinafter provided shall have a width greater than 35 feet measured at right angles to the centerline of the driveway, except as increased by permissible radii. In no instance shall a driveway have a width greater than 62 feet, including flare of return radii, measured along a line 10 feet from and parallel to the edge of the pavement on which the entrance will be constructed.(2) RETURN RADII. No return radius projected between the edge of highway pavement and the driveway shall be greater than 40 feet. Usually, these radii will be determined by the restrictions given in subs. (1), (3), and (4). (3) ANGULAR PLACEMENT OF DRIVE. The angle between the centerline of a driveway serving two-way traffic and the edge of the pavement may not be less than 45°. Where suitable precautions are taken, or one-way operation along divided highways permits only one-way operation of the driveways, the angle of the entrance drive to grantee's property may be decreased. The angle of the exit drive with the highway pavement shall be not less than 45°.(4) ISLAND AREAS. (a) An island of a minimum length of 10 feet shall be maintained between driveways serving the same premises. The measurement shall be along a line 10 feet from and parallel to edge of pavement. The permit shall specify that the island area, if less than 20 feet in length or 10 feet in width, is to be defined by physical structures such as curbs, posts, boulders, masonry walls or guard rails. Materials used to define the island, except concrete curbs, shall be painted white. The side of the island next to the highway shall be not less than 10 feet from the pavement edge. The side of the island farthest from the highway shall be at the right-of-way line.(b) The area within 5 feet of a property line shall be a restricted area over which no driveway may be developed. The 5-foot restriction shall be measured parallel to the pavement edge and shall be effective between the right-of-way line and a line 10 feet from and parallel to the pavement edge. This is to serve as an island area should the adjoining property owner request a permit for a driveway.Wis. Admin. Code Department of Transportation § Trans 231.04
