    Latest upcoming road closure dates

    Work started from Monday 9 October 2023 and continues until the end of January 2024.

    We're working overnight between 8pm to 6am on weeknights only, weather conditions permitting. 

    To carry out the work safely, we need to close both directions of the A120, from Marks Farm (Braintree) to Marks Tey (Colchester) and divert traffic as detailed below.

    Please note that Arriva and First Bus overnight services will be affected by our closures. Please refer to their websites for updates to their bus services and scheduled times.

    Eastbound traffic: Traffic will be diverted at Marks Farm roundabout, join the A120 until Great Notley Roundabout, join the A131, A130, join the A12 at Junction 19 and continue north on the A12 until Junction 25.

    Westbound traffic: Continue on A12 until junction 19, join the A130, A131 and rejoin the A120 at Great Notley Roundabout.

    There is local access to properties and businesses during the night closures. We are providing traffic management escort service to properties from gated access points along the route, so please expect delays. Some properties have an intercom system to contact the traffic management escort.

    Access to local properties during the road closures

    Local residents and businesses will be escorted to their properties and premises during the overnight closures. Please refer to the table below and enter at the correct gate, as we'll only be able to escort to the properties shown within each phase.

    We advise that journeys are kept to a minimum. However, if you require to leave your property during the closure, please let our traffic management crew know. Some properties will have either an intercom system to contact the escort crew or a traffic management member located at the gate.
