of the county or State roads in said county, but before any
of said mains shall be placed in or under any of the State
highways, a permit shall be obtained from the State Roads
Commission. Provided, however, that where any mains
are laid in or under any of said highways the said roads
or highways shall be restored to the same condition, as
