During the 17th century, a handful of major public roads (High Street, Main Street, Salem Street, "the road to Stoneham", and South Street) served the population, but the road network started a long-term expansion in the 18th century. The Medford Turnpike Company was incorporated in 1803, and (as was reasonably common at the time) turned what is now Mystic Avenue over to the city in 1866. The Andover Turnpike Company was incorporated in 1805, and turned what is now Forest Street and Fellsway West over to Medford in 1830.
