Potomac Community Eruv
The Potomac Eruv is basically a triangle with the eastern edge being I-270. At the corner of I-270 and Falls road, the eruv goes south on Falls Rd, makes a left at Bells Mill, takes a right at Democracy Lane, turns left at Democracy Blvd, then left at Westlake Dr, and finally connects with the I-270 fence at the power station south of Tuckerman. The Eruv is cheked each week by a group of volunteers led by Dr. Robert Kreitman. An email is sent each week to the YIEIP listserv indicating whether the eruv is up. One must check to determine that the eruv is up each week before relying upon it to carry on Shabbat.
