346.57(4)(i)(i) Fifteen miles per hour on any street or town road, except a state trunk highway or connecting highway, within, contiguous to or adjacent to a public park or recreation area when children are going to or from or are playing within such area, when the local authority has enacted an ordinance regulating such traffic and has properly marked such area with official traffic control devices erected at such points as said authority deems necessary and at those points on the streets or town roads concerned where persons traversing the same would enter such area from an area where a different speed limit is in effect.

346.57(4)(j)(j) Thirty-five miles per hour on any town road where on either side of the highway within any 1,000 feet along such highway the buildings in use for business, industrial or residential purposes fronting thereon average less than 150 feet apart, provided the town board has adopted an ordinance determining such speed limit and has posted signs at such points as the town board deems necessary to give adequate warning to users of the town road.

The signs shall be erected at such points as the authority in charge of maintenance deems necessary to give adequate warning to users of the highway in question, but an alleged failure to post a highway as required by this paragraph is not a defense to a prosecution for violation of the speed limits specified in sub. (4) (e), (f), (g) or (k), or in an ordinance enacted in conformity therewith, if official signs giving notice of the speed limit have been erected at those points on the highway in question where a person traversing such highway would enter it from an area where a different speed limit is in effect.

346.57(6)(b)(b) The limit specified under sub. (4) (gm) is not effective unless official signs giving notice of the limit have been erected by the department.
