Oasis Bridge is located in Chelmsford on the B1137 Springfield Road, close to the Eastern Approach/Cuton Hall Lane/Colchester Road roundabout (near the B&Q store), and carries the A138 Chelmer Road dual carriageway over Springfield Road.
Arrangements have been made to refurbish this four span bridge and install new vehicle safety barriers known as a vehicle restraint system (VRS) as well as inspection platforms to support future surveys.
The existing bridge bearings will also be replaced due to signs of deterioration, and a survey will take place to assess and repair defects to the concrete abutments. The bridge expansion joints will also be renewed and the bridge will be re-waterproofed before being resurfaced. These works are necessary to maintain the integrity of the structure.
The site is particularly challenging due to the limited working area and close proximity to utility services. We are also managing the work programme to minimise local traffic disruption as this is a traffic sensitive site in Chelmsford and will be co-ordinating the work with other schemes being planned for the area including Boreham Capacity Improvements (managed by Countryside Properties).
We currently estimate the bridge refurbishment works will take eight months to complete assuming no delays are incurred.
Throughout the various phases of the works, traffic management will be adjusted to ensure the safety of the public and workforce is maintained. We anticipate this will include the following, however advance notice of key traffic management changes will be published in advance on site signage.
- Much of the work will be carried out with the support of single carriageway closures on B1137 Springfield Road to maintain traffic flows in both directions during the day and night.
- A temporary contra-flow will be used to maintain the traffic flow over the bridge on the A138 Chelmer Road during certain aspect of the works.
- Full night time road closures over the bridge will be required for jacking and de-jacking of the bridge, required during bearing replacement works.
- Additional night time full road closure of the A138 will be required for installation of contra flow traffic management and reinstatement of white lining and road studs. Appropriate diversions will be put in place during any planned road closures.
What is involved and how it may affect you
The main works are proposed to begin Monday 19 April 2021 and are programmed to be completed in approximately eight months, subject to weather permitting and no unexpected issues arising. Some advance vegetation clearance works are anticipated to accommodate the site compound, prior to the bird nesting season.
While every effort will be made to minimise the impact of the works to traffic and local businesses, delays should be expected. Please allow extra travelling time for your journeys, observing traffic management in place.
Pedestrian routes will be maintained via a designated diversion route throughout the scheme.
Information relating to programmed traffic management phasing will be published as details are confirmed.
Please note that the work programme may be subject to change if works are affected by poor weather or if unexpected issues arise.
We will share the latest information about the works and progress updates on this webpage as the scheme progresses.
