Bus users are reminded that revised local routes, timetables and service numbers come into effect on Sunday, 10 April.
Essex County Council is recommending passengers, particularly those taking ECC supported buses to school or work, check online before taking their journeys.

The majority of contracted school buses are unaffected.
An Essex County Council spokesman said the revised services are the result of a wide ranging passenger transport review and public consultation carried out in 2015.
He added: “The changes are principally to evening, Sunday and rural services. We are aiming to create a more efficient, sustainable and cost effective network for the future.”
