The commissioners elected and holding office in a county where a road has already been completed under the above entitled act are hereby continued for their respective terms. The commissioners first to be elected in a county in which a road shall hereafter be completed under the above entitled act shall be elected at the general election next following its completion. The proceedings touching the nomination and election of all such commissioners shall conform in all respects to the method of nominating and electing members of the general assembly. They shall be voted for on the same ticket, but in order to secure minority representation on the board, no voter shall at any election vote upon his ballot for more than two commissioners, and upon the canvass of the election the three persons receiving the highest number of votes for such position shall be declared elected, and the county clerk shall, on their qualification, give to each a certificate of his election and qualification. Until the first election and qualification of the commissioners, the board of chosen freeholders shall control, maintain and repair such roads as heretofore.
