The works to construct the access road and bridge as part of the wider Chelmer Waterside project are continuing. During these works you will see contractors from GRAHAM delivering the works on behalf of Chelmsford City Council. |

 Over the last few weeks, the following works have been completed:
- New river edge alignment concrete wall
- Bridge foundation piles
- The main structure pile caps have been constructed for 5 out of the 6 bases. This has involved:
- Reinforcing steel being tied into place
- Timber shuttering erected to form the concrete
- Concrete poured into the timber form
- Timber shuttering removed
- Concrete waterproofed
- Structural stone back filled and compacted around the new structure
- Topsoil strip has commenced on the new flood attenuation area south-east of the Baddow Road car park on the southern bank of the River Chelmer
- The south side of the River Chelmer has been dredged restoring a section of the navigable channel.

 The next stages of works are to:
- Complete the remaining bridge pile cap foundations
- Form the abutments and piers for the bridge support walls
- Excavate the flood attenuation area
- Start the drainage in Baddow Road Car Park

The tied arch bridge design in weathering steel was chosen for a number of reasons. The design reflects the industrial heritage of the former gas works land. It also maximises the opportunity for river clearance by reducing the depth of structural elements located underneath the deck. This will allow for future navigation of this section of the waterway. Weathering steel is a steel alloy which has been developed to eliminate the need for painting, and forms a stable rust-like appearance after several years' exposure to weather.
There are 280 tonnes of structural steel being used in the main bridge span and the bridge will be lifted into place in two parts via a 500 tonne crawler crane.
