Every board of park commissioners or park authorities may connect any public park, boulevard or driveway under its control with any part of any incorporated city, town or village by selecting and taking any connecting street or part thereof leading to such park, boulevard or driveway, and may accept and add to any park under its control any street or part thereof which adjoins or runs parallel to a boundary line of such park. Streets so selected, to the extent taken, must lie within the territory of the park district. The consent of the corporate authorities having control of a street so selected and the consent in writing of the owners of a majority of the frontage of the land abutting the part of the street that has been selected must be obtained before that part may be taken.
