(1) No limited access highway shall be constructed that will result in the severance or destruction of an existing recreational trail of substantial usage for pedestrians, equestrians or bicyclists unless an alternative recreational trail, satisfactory to the authority having jurisdiction over the trail being severed or destroyed, either exists or is reestablished at the time the limited access highway is constructed. If a proposed limited access highway will sever a planned recreational trail which is part of a comprehensive plan for trails adopted by a state or local governmental authority, and no alternative route for the planned trail exists which is satisfactory to the authority which adopted the comprehensive plan for trails, the state or local agency proposing to construct the limited access highway shall design the facility and acquire sufficient right-of-way to accommodate future construction of the portion of the trail which will properly lie within the highway right-of-way. Thereafter when such trail is developed and constructed by the authority having jurisdiction over the trail, the state or local agency which constructed the limited access highway shall develop and construct the portion of such trail lying within the right-of-way of the limited access highway.
(2) Where a highway other than a limited access highway crosses a recreational trail of substantial usage for pedestrians, equestrians, or bicyclists, signing sufficient to insure safety shall be provided.
(3) Where the construction or reconstruction of a highway other than a limited access highway would destroy the usefulness of an existing recreational trail of substantial usage for pedestrians, equestrians, or bicyclists or of a planned recreational trail for pedestrians, equestrians, or bicyclists incorporated into the comprehensive plans for trails of the state or any of its political subdivisions, replacement land, space, or facilities shall be provided and where such recreational trails exist at the time of taking, reconstruction of said recreational trails shall be undertaken.
