Precinct 137A contains territory on both sides of the river (as before) and its eastern border is unchanged. However the northern border is now the Connecticut Turnpike (I-95) until reaching the Norden Place - Triangle Street - Sasqua Road - Duck Pond Road parcel which is in Precinct 143A (as before).

Precinct 137A votes at Marvin Elementary School (as before). The territory north of the turnpike which was previously part of 137A is now in District 143 (if east of East Avenue) or in Precinct 137B (if west of East Avenue).
