History
The route from Woonsocket to Wrentham was assigned as Route 142 in the early 1920s when the New England states began numbering their state highways. Route 142 ran for about 11 miles (18 km) between Route 122 and current Route 1A (then designated as U.S. Route 1). It used present-day Route 114 from Route 122 in Woonsocket and Cumberland, then along present-day Route 121 to Wrentham.
Around 1933, the entire route (in both Rhode Island and Massachusetts) was renumbered as Route 11 and its northern end extended into Dedham along old Route 1 (current Route 1A) when Route 1 was realigned. Route 11 was later cut back to its original length after a few years when Route 1A was designated in the area.
