This link will take you to a map, created by the Republican Registrar of Voters for Middletown.

On the map, each city district, 1-14 is shown, designated by a number in a circle.  Above the number is the Voting Location.  Below the number is, respectively, the US Congressional, State Senate and State House district.

For example, if you live west of Pine Street, between Washington and Wadsworth, you are in City District 7.  You vote at Snow School.  You are in US Congressional District 3; State Senate District 9; and State House District 33.  To find your current representatives, see the Middletown City Registrar of Voters page.  When you get to the page, scroll down to the Voting Locations.
