Route 114 is a Massachusetts state route that essentially is a northwest-southeast route, but is technically considered to go east–west. It runs from Route 28 in Lawrence to Route 129 in Marblehead, Massachusetts, which also terminates there.
I-495, I-95, and Route 128 are major freeways that have interchanges with Route 114. US 1, Route 107, and Route 62 also have interchanges with the route.

Route 114 is not related to Route 114A in Seekonk, which is actually related to Rhode Island Route 114 and is located about away from Massachusetts Route 114.

History

For about its first three decades, Route 114 originally went only as far as Salem. The route was extended to Marblehead in the late 1950s.

Between 1997 and 2002, Route 114 was extended through what had been Route 129's end in prior and subsequent years when Route 129 was extended to end at nearby local roads. After 2002, the roads reverted to their prior forms.

Other than these extensions, no other changes to the route have been made.
