§ 1652-a. Traffic signs, signals and marking on highways, roads and
streets. The county superintendent of highways of a county, except the
county of Suffolk, having a functioning traffic engineering unit may,
when authorized by the county governing board, have the responsibility
and authority for the installation, removal and maintenance of traffic
signs, signals and markings on, and provide traffic engineering services
in relation to any highway, road or street within a city, town or
village within such county, except state highways maintained by the
state, providing the governing body of the city, town or village
consents thereto by written agreement with the county governing board as
to the extent of the authority and responsibility of the county
superintendent of highways and any apportionment of costs for the
installation, removal and maintenance of the signs, signals and markings
and traffic engineering services. The power granted to the county
superintendent of highways by this section shall in no way diminish any
power over roads granted to counties or county highway superintendents
but shall be in addition to any such powers.
