Section 7. Surveyors of highways and road commissioners shall remove whatever obstructs the public ways within their respective towns or districts, or endangers, hinders or incommodes persons traveling thereon; and shall forthwith cause snow to be removed or trodden down so as to make such ways reasonably safe and convenient. If a town neglects to vote a sufficient amount for the proper repair of ways therein, or does not otherwise effectually provide therefor, each surveyor, in his district, or the road commissioners, may employ persons to make such repairs, who shall be paid by the town; and towns may authorize their surveyors or road commissioners or any other person to enter into contracts for making or repairing the ways therein.
