The Derby Turnpike Company was chartered to build a toll road from New Haven to Derby in May 1798. It ran from downtown New Haven, beginning at York Street, and followed Chapel Street to Derby Avenue, which connected to modern Route 34 and continued to downtown Derby. The Derby Turnpike was the longest-lived of the state's early toll roads and only stopped collecting tolls in 1895. West of downtown Derby, another turnpike corporation, the Ousatonic Turnpike, was chartered also in 1795 to build a toll road between Derby and New Milford following the east bank of the Housatonic River. Unlike the Derby Turnpike, the Ousatonic proved to be unprofitable. In 1813, the portion between Southbury and New Milford was discontinued as a toll road. In 1834, the northern half of the remaining portion (north of the present Stevenson Dam) was given to another company, the River Turnpike Company, to try to make the road profitable. In 1841, however, the River Turnpike road reverted to the Ousatonic, and the Ousatonic company itself was dissolved the following year in 1842. The portion of the old Ousatonic road north of Stevenson Dam is now mostly submerged as a result of the damming of the Housatonic to form Lake Zoar and Lake Lillinonah.
