The story

The Estuary Transit District was founded in 1981 and operated 9 Town Transit bus service in the Old Saybrook area. XtraMile microtransit service in the Old Saybrook area began in 2019. Middletown Area Transit merged into the Estuary Transit District on July 1, 2022. XtraMile service was added in Middletown later in 2022. On March 27, 2023, the system was rebranded as River Valley Transit, replacing the old 9 Town Transit and Middletown Area Transit names. In May 2024, two additional microtransit service zones were added.
