ditional property and rights as it may require to construct the same. The
bridge which said railroad company shall construct for an overhead cross-
ing or the tunnel for the undergrade crossing shall he at least twenty feet
wide, and the height of said tunnel from the surface of the roadway through
it shall not he less than fourteen feet; and the grades approaching said
overhead or undergrade crossings shall not he greater than a rise of six feet
in the hundred. The said " tunnel" used in this section to describe the
undergrade crossing may either be arched or the railroad tracks may be
carried across the public highway on a bridge, as the railroad company may
elect. For constructing the approaches to said overhead or undergrade
crossings the railroad company may, at its own expense, change the grade
of the public highway to be carried on said new crossing with the same
rights and liabilities as are now vested in the county commissioners in
changing the grades of public highways. Whenever a railroad company
shall construct an overhead or undergrade crossing under the terms of this
section, all grade crossings within six hundred yards of the same may be
closed by it and no new crossing shall be opened within that distance of
said overhead or undergrade crossing; provided, that this prohibition as
to the maintenance and opening of grade crossings shall not apply to
incorporated towns or villages of two thousand or more inhabitants, subject,
however, to the consent of the county commissioners or municipal authori-
ties of said counties and towns.
