For more information about the campaign, please view our campaign letter.

Our Mission: We operate and maintain the Greater Boston Eruv, one of the largest Eruvim in the world. The Eruv allows people within its borders to carry objects with them on the Shabbat, an activity that would otherwise be proscribed by Jewish law.

Our Scope: The Greater Boston Eruv covers major parts of Brookline, Newton, and Brighton. An initial extension of the Eruv to include Nonantum (See the map!) was followed by expansion into most of South Newton. During Sukkot 5766, we completed a third extension to the Eruv that includes a significant portion of Boston University. In 5771, we added another small section in the Newton area. We also manage the Malden, MA (extended in December 2014) and the Brandeis University Eruv (which was extended into Waltham during the Fall of 2015). Beginning in 2014, we began two simultaneous projects, one to extend the Eruv into more of South Brookline and, for the first time, into West Roxbury, and a new Eruv on the North Shore (Marblehead, Salem, Swampscott). Our new South Brookline/West Roxbury extension was ready for service as of Erev Yom Kippur 5777. Our Swampscott Eruv (Phase 1) went online in the Fall of 2016.

   May 9, 2024 - Upcoming Expansion to Malden Eruv

Eruv      The Malden community is once again preparing to extend the existing Eruv to accommodate families who have moved into homes outside the Eruv. With our license permit from Verizon in-hand and other related permits, we are ready to enter the construction phase. Rabbi Yitzchak Rabinowitz and Synagogue Administrator Matthew Garland of Congregation Beth Israel, Dan Strom (our Eruv contractor), and Dr. Jesse Hefter (President of the Greater Boston Eruv) met today to walk the new route and review installation requirements for the Eruv attachments. (The image to the left shows Rabbi Rabinowitz (L) and Dr. Hefter (R))

   April 12, 2024 - Eruv Chatzerot at Brandeis University

Eruv      It was once again a pleasure to meet with students at the Minyan at Brandeis together with Rabbi Ariel Cohen and Rabbi Seth Winberg to perform an Eruv Chatzerot for the upcoming year. Dr. Hefter provided a context for the ceremony pointing out that, in addition to requiring that the mechitzot that form the local Eruv are in acceptable status, it is also required that some food be placed in a common area that is accessible to anyone who might need it (especially for the Shabbat). This requirement represents a physical aspect of the ceremony. Further, the Rabbis instituted that we overlay this setting aside of the food with a Bracha and a statement to elevate the ceremony to one of the spirit.

   November 8, 2023 - Haskamot of Harav Moshe Heinemann

Eruv      We have scanned two important documents prepared by Harav Moshe Heinemann for our Eruv in 5764 (2004). The first is a statement of the validity of the Community Eruv. The second is a Teshuva (legal decision) regarding the question of an Eruv that spans multiple neighborhoods where some of the neighborhoods are split by a roadway or highway. This latter question arose here in Boston with the Massachusetts Turnpike bisecting part of the Eruv. The PDF documents are available on the "About" page. We have tremendous Hakaras HaTov for his guidance, leadership, and friendship over the decades!

   November 6, 2023 - Arcadian Hotel - Brookline - Discount Room Rates

Eruv      The Arcadian Hotel, located in the heart of Coolidge Corner and near several synagogues, now offers discounted booking rates for those staying in Brookline over Shabbat. To make your reservation, please use the promo code 'BOSTONERUV10' and use this link.

   October 22, 2023 - OU Sponsors National Eruv Conference

Eruv      The Orthodox Union sponsored a two-day conference for Eruv professionals on October 22 and 23, 2023. The event drew over 60 Eruv professionals across the religious spectrum from 35 cities in 10 states, as well as from Canada. The conference enabled participants to create a network of like-minded individuals who can share of their knowledge and expertise. Further, the participants drew chizuk from the lectures and workshops. You can read more about the conference at the link that follows: Link to the conference article

   September 27, 2023 - Another season at the Larz Anderson Lagoon

Eruv      Another season of utilizing the Larz Anderson Lagoon in South Brookline began today. Each year, starting after Yom Kippur, we place a radio-controlled boat onto the lagoon and have it travel over the water for at least 18 minutes. In order for this procedure to work, that is, to include the lagoon within the Eruv, this activity must be performed a majority of the weeks of the year (which for this Eruv extension started on Yom Kippur, in 2018) which is at least 27 weeks of the year.

   September 13, 2023 - The Winter Eruv for Camp Ramah is ready!

Eruv      We visited the Camp Ramah (Palmer, MA) to ensure that a subset of the main Eruv is ready for fall and winter visitors. We call it the Ramah Winter Eruv. Rabbi Bruce Seltzer, who is responsible for the Camp Eruv met Dr. Jesse Hefter for a complete review of the perimter. Together, we found a series of issues that were carefully remedied. After about 4 hours of work (some in the rain and some in the sun), the Eruv border was completed and is ready for use!
You can read more about the Camp Ramah Eruv here.

   July 9, 2023 - An Eruv for Hong Kong!

Eruv      A portion of Hong Kong, China, was recently encircled by an Eruv. This allows the roughly 3,000 Jewish residents there to more easily move around on the Shabbat. The Eruv was announced in the Times of Israel and you can read about it here

   May 31, 2023 - Maimonides School 6th-Grade Eruv Tour

Eruv      The sixth grade at the Maimonides School in Brookline invited Dr. Jesse Hefter, President of the Greater Boston Eruv, to visit their class and provide some background about Eruv design, halacha, and real-world implementation. The students had just learned several section of Masechet Eiruvin Mishnayot and the presentation helped the students (and teachers) to connect the legal material to the actual implementation. After about a 40 minute classroom dialog, we walked several blocks to the edge of the Eruv and saw the border elements right up-close. The student feedback was positive - connecting classroom content with the real world in actual practice.

   March 31, 2023 - Brandeis University, Waltham executes Eiruv Chatzeros for the Coming Year

Eruv      Dr. Jesse Hefter was invited by Rabbi Seth Winberg and Rabbi Ariel Cohen to meet with representative students from the University and execute a fresh Eireuv Chatzeros for the coming year. The students are always excited to participate in this important ceremony!

   February 11, 2023 - 'Uv-ney Yisroel Yotz-im B'Yad Ramah' - An invited presentation to Congregation Kadimah-Toras Moshe

Eruv      Dr. Jesse Hefter was invited by Rabbi Jason Strauss and President Andy Rubin of Brighton's Congregation Kadimah-Torah Moshe to present a Dvar Torah and Funding presentation on Shabbos Yisro to the congregation. We appreciate the opportunity to get the Eruv's message out to the community!

A copy of the Dvar Torah is available.

   February 10, 2023 - South Brookline Infrastructure Update

Eruv      We met with the head of Landscaping and Horticulture at Chestnut Hill Realty in South Brookline to determine how to access a set of Tzuros HaPesach that are hemmed in by a huge dirt pile. In the process of creating the dirt pile, two twine segments were broken. Since the segments in question are part of an exclusion from the main Eruv, the repair is not immediately required.

Our teams reviewed the situation and determined next steps for repairing the two twine segments that will serve our purposes and be out of the way of the continuing construction activities (i.e., the creation of a new parking lot behind a large set of apartments).

We appreciate the continuing support and cooperation from the CHR staff!
