In the early 1800s, the legislature of Ohio authorized many state roads to be constructed, in order to connect the major cities of the state with well-engineered roadways (in order to replace the often-treacherous Native American trails, which were still the primary thoroughfares).[3] The Worthington-New Haven state road was built circa 1820 after an act passed by the General Assembly authorized its construction.[4][5][6] Unlike many other pre-railroad state roads around Ohio, the New Haven road was evidently not significantly realigned over its lifetime, with exception of the section near Alum Creek Lake (which partially inundated the road south of U.S. Route 36).
