There is one weigh station located northbound at milepost 2 in Greenwich, at the location of the former toll plaza. Weigh stations on both sides of the turnpike used to exist near exit 18 in Westport; these were removed during the 1990s. The former southbound weigh station in Westport is now used by ConnDOT to store construction materials, while the northbound station was demolished; the grounds returned to their natural state.
