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 investing around £32m to rebuild the Ardleigh Green Bridge.
We are replacing it with a new bridge with wider carriageways, footways and verges, and taller parapets to protect cyclists and pedestrians.
Demolition of the eastern section of the Ardleigh Green Bridge is under way. We are coordinating with Network Rail's existing planned rail closures so there is as little disruption as possible.
The new bridge is on site, ready for launch in 2017.
A temporary contraflow (a single lane in each direction) is in place on the A127 from Gallows Corner to Squirrels Heath Road. The Essex-bound carriageway is closed completely and two-way traffic is operating on the other side of the road.
The contraflow will be in place on the eastern side of the road first for around nine months before works begin on the demolition and replacement of the western side of the bridge in spring 2017.
The entrance to Bryant Avenue from the A127 is closed to traffic while works to build a new section of the bridge are completed.
Vehicle access to Bryant Avenue will be possible during this period via the A12, with all traffic continuing to leave Bryant Avenue via the junction with the A12.
The existing closure of the Bryant Avenue exit onto the A127 will continue until spring 2017 while demolition and replacement of the eastern half (the Essex-bound carriageway) takes place.
Pedestrian access across the A127 and Bryant Avenue will be maintained 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.
While we are rebuilding the eastern side of the bridge, pedestrians are being diverted onto the new service bridge on the same side - please follow the signed route. The footway along the western side of the bridge will remain open.
The new road bridge will have wider footways on both sides. The project will have no effect on the footbridge over the A127 at the junction with Ardleigh Green Road/Squirrels Heath Road.
We will keep night works to a minimum. Whenever possible, work will take place during the day between 08:00-18:00 Monday to Friday and 08:00-13:00 on Saturday.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, Ramboll and Parson Brinckerhoff, and Skanska.
