Worcester is located approximately 40 mi west of Boston , 50 mi east of Springfield and 40 mi north of Providence . Due to its location in Central Massachusetts , Worcester is known as the `` Heart of the Commonwealth '' , thus , a heart is the official symbol of the city .

Worcester was considered its own region for centuries ; however , with the encroachment of Boston 's suburbs in the 1970s after the construction of Interstate 495 and Interstate 290 , it now marks the western periphery of the Boston-Worcester-Providence -LRB- MA-RI-NH -RRB- U.S. Census Combined Statistical Area -LRB- CSA -RRB- , or Greater Boston .
