In Massachusetts advocates of better roads attempted legislation looking toward a system of state highways in 1887 and annually thereafter until 1892.[152] In 1892 the demand became so great that the legislature enacted a law providing for a commission of three to inquire into the entire subject and report to the legislature of 1893, with suitable appropriation for the purpose. The commission made a thorough investigation, held public hearings, and made inquiries among all classes. Their findings were brought before the legislature and a general road law was enacted providing for a commission of three competent persons who should give advice to those having charge of the public highways; it further contemplated the building and care for by this commission of a system of state highways connecting the several municipalities. At first the counties were supposed to grade the roads and the Commonwealth to surface them but the law was changed (1894) so that the Commonwealth through the highway commission does the entire work of construction and maintenance then charges back to the counties 25 per cent of the cost, so that finally the State pays 75 per cent and the county 25 per cent. In 1913 an amendment was made to relieve small communities from the payment of the entire amount thus the State, in reality, pays more than 75 per cent of the expense. The state aid principle has been adopted by all states in the union; many before federal aid came, the remainder since. Connecticut was third in 1895 and New York fourth in 1898.
