The bridge is at the end of its useful life and is beyond simple repair. Not replacing the bridge would mean restricting the weight of vehicles and closing lanes to carry out maintenance, causing disruption in the future.
We are replacing it with a new bridge with wider carriageways, footways and verges, and taller parapets to protect cyclists and pedestrians.
We're now working towards demolishing and rebuilding the London-bound section (the western section) of bridge.
We finished replacing the Essex-bound section of Ardleigh Green Bridge (the eastern section) and switched traffic onto it in December 2017.
The demolition of the western section will take place over two weekends in spring/summer 2018. After summer 2018 the new western bridge will be installed and works will begin to build the new road.
Details of these works, including any road closures, will be on this page nearer the time.
We're on track to reopen all four lanes of traffic on the A127 by spring 2019.
The eastern side of the old bridge was demolished between 28 April and 2 May 2017.
The London-bound carriageway is closed completely and a temporary contraflow - a single lane of traffic in each direction - is in place in the Essex-bound carriageway. There will still be access to all side roads off the A127 at all times.
At all times during the works we will ensure there is a safe route for pedestrians to cross the railway, on both sides of the bridge.
Work will take place in the area on weekdays and on some weekends 08:00-18:00 - as agreed with the London Borough of Havering. Some works will also take place at night to coincide with the planned railway closures.
We will always do as many of the noisiest works as possible in the daytime shifts.During the works we are using a range of measures to reduce noise, vibration and disruption, including:
We will also have recycling skips on site to ensure we recycle everything we can.
We are working closely with Network Rail to minimise disruption and ensure the works proceed as safely, efficiently and quickly as possible.
We are delivering this project in partnership with Hochtief (UK) Construction.
