Route description

SR 661 travels through northern Licking County and southern Knox County. No portion of this state route is included within the National Highway System (NHS). The NHS is a network of highways identified as being most important for the economy, mobility and defense of the nation.^[5]

History

The SR 661 designation was created in 1937. It was originally routed along its current path between Granville, at the eastern intersection with Broadway Avenue, the former routing of SR 16, and the southern end of Mount Vernon. However, instead of turning east onto Blackjack Road, as it does now, it continued north along Granville Road up to where it meets SR 13 just south of downtown Mount Vernon. That point marked the original northern terminus of SR 661.^[1][2]

By 1964, a new freeway opened to the south of Granville. SR 16 was re-routed off of Broadway Avenue onto the by-pass. Consequently, SR 661 was extended a short distance to the south by following Broadway Avenue west to Main Street, and then heading south along the former routing of SR 37 to the interchange with the SR 16/SRnbsp;37 freeway that currently marks the southern terminus of SR 661.^[6][7] On the northern end, SR 661 was re-routed off of Granville Road onto Blackjack Road heading east to a new terminus at SR 13 in the southern end of Mount Vernon in 1983.^[8][9]
