1930s, many of these routes were transferred to state highway systems, often retaining their original route numbers. Background Before 1915, there was no uniform method to mark major throughways in New England or New York. Vermont and New Hampshire had existing pole marking schemes, though these varied between the states. Vermont's system was unique because route colors were not determined by direction, but by funding and responsibility for maintenance. Maine also had an existing lettering scheme, established in 1914. Many states at this time had numbering systems solely for government use. For example, Connecticut had established an internal system of trunk lines in 1900, which had grown to 14 routes by 1913, but this system was not signposted. In 1908, the New York legislature had laid out 37 routes slated for maintenance solely by the state, but there was no proper numbering until 1924. In 1915, the Massachusetts Highway Commission proposed to the New England States and New York to adopt a uniform pole-marking scheme, with red bands signifying major east-west routes, blue bands signifying major north-south routes, and all secondary routes marked yellow. All the states agreed to the system, though New Hampshire and Vermont stipulated that these routes would not replace their existing systems. This system held in most of these states, though Maine supplanted this system in 1919 with its own system of auto trails. By 1922, it was generally agreed that pole markings in general were too inconsistent from region to region. In April 1922, delegates from the New England states met at a dinner conference hosted by the Automobile Club of America to coordinate a new system. Soon thereafter, the system was approved by the highway commissions of all the states involved, and signing began soon thereafter. Maine did not use the system until 1925. Routes by number Interstate routes Route 1 Route 1, or the Atlantic Highway, began in Greenwich, Connecticut, from which the main highway of the Atlantic Coast continued to New York City. The highway followed the coast of Long Island Sound through Stamford, Norwalk, and Bridgeport to Stratford, where the highway met the southern end of Route 8. Route 1 continued through Milford and had a junction with Route 2 in New Haven. The highway continued east to Old Saybrook, where it met the southern terminus of Route 10 and crossed the Connecticut River. Route 1 met the southern ends of
