Englewood-Tenafly
In an effort to maintain an Eruv of the highest practical quality while encompassing as much area as we can, the Englewood Jewish Community has established an Eruv with two distinct sections because contemporary authorities debate whether Route 4 is considered an intercity highway that cannot be included in an Eruv. Approximately 90% of our Eruv satisfies the most stringent opinions who do not permit Route 4 to be included in an Eruv. This area is identified as Area A (shaded in green). A much smaller area, identified as Area B, is shaded in blue. By necessity, Area B includes Route 4 but remains in accordance with the view of Rav Moshe Feinstein and the practice of the Jerusalem Eruv (which encompasses the Jerusalem-Tel Aviv Highway).
Areas A and B overlap where Route 4 passes over Broad Ave and where it passes underneath Jones Rd. Area A includes only Broad Ave and Jones Rd; Route 4 itself is included only in Area B.
