is a numbered State Highway running 4.2 miles in
Rhode Island .
Route 120 takes the following route through the State:
Many maps erroneously show Route 120 extending west from
Route 122 to
Route 146 . Signage very clearly shows this to be incorrect. The routing shown on most maps continues Route 120 north on
Route 122 for about one block, then heading southwest on Manville Hill Road to
Route 126 , where it travels north with
Route 126 to Sayles Hill Road, then southwest on Sayles Hill Road to
Route 146 .
Though Route 120 does not extend past
Route 122 , a state-maintained road continues past an interchange with
Route 99 to
Route 146 .
