Repair of Unstead and Unstead New Cut Bridges in Shalford

Coronavirus: how the outbreak is affecting our roadworks and maintenance

Surrey County Council is resuming its essential roadworks programme to help keep routes open and safe for key workers during the coronavirus restrictions. More information and updates can be found on our Roadworks Coronavirus page.

Activities to recommence whilst observing the government guidelines for social distancing:

  • We will be recommencing works on site from 11 May 2020
  • This work will be undertaken with government guidelines in place and safe operating processes for both staff and the general public

The site will be made safe by the end of Friday 27 March and closed until further notice. Please check this page for further updates on this work site.

What does the scheme involve?

This scheme combines works at both Unstead Bridge and Unstead New Cut Bridge in Shalford. Both structures are in close proximity to each other, therefore the works will be co-ordinated. Unstead Bridge is located on Tiltham's Corner Road immediately west of the junction with Unstead Lane, and Unstead New Cut Bridge is located approximately 50m west of Unstead Bridge.

Tilthams Corner Road will be closed 24 hours a day, seven days a week for the full 18 week duration of this work. Due to the narrow width of the road we do not have sufficient space to maintain traffic or pedestrian access safely, so a hard closure is necessary during this work.

Unstead Bridge:

The proposed works involve raising the stone walls to accommodate the installation of a reinforced concrete beam behind the existing kerb lines. A second tier of granite kerb units will be installed behind the existing kerbs. The extra kerb lines will provide greater vehicle containment across the structure, and also provide a greater 'visual barrier' on approach to the bridge.

The stone walls will be locally raised to match the level of the raised kerbs. This will be achieved with Bargate Stone to match the existing walls. The existing parapets will be replaced with fabricated steel replicas to closely match the originals in visual appearance.

Unstead New Cut:

We will be raising the kerbs to provide a double height kerb and replace the parapet like for like.

The structures will look the same at the end of the works, however there will be an increase in kerb height.

How long will the works take?

The scheme will require specialist and skilled contractors to repair the stone work. We have strict conditions set under listed building consent which need to be adhered to. We anticipate the duration of this scheme will be approximately 18 weeks. Where time savings can be made we will endeavor to do so.

Will the road be closed during the scheme?

Yes. We will need to have Tilthams Corner Road closed for the duration of the scheme. The road is very narrow and we do not have sufficient space to safely maintain traffic or pedestrian access. In addition, as the area is a Site of Special Scientific Interest (SSSI) which is managed by Natural England we are unable to erect scaffolding on the land. We are building a scaffold from the road side, up and over the structure.

Will there be pedestrian access?

There will be no pedestrian access between the two bridges due to the nature of the scaffolding arrangement.

What permits are required for the scheme?

Permits have been obtained from:

  • the Environment Agency for Unstead Newcut Bridge only (Flood risk Permit),
  • Natural England (as the area is a Site of Special Scientific Interest (SSSI)
  • Waverley Borough Planning – Listed Building Consent for Unstead Bridge.

What will the diversion be for vehicles?

Access for pedestrians, cyclists and equestrians will be maintained at all times via Trunley Heath Lane, Horsham Road, Bridleway 580, (Unstead Wood Footbridge canal path), Broadford Road, Old Portsmouth Road and Tilthams Corner Road.

Access for emergency vehicles, local residences and businesses will be maintained at all times via Trunley Heath Lane, Horsham Road, Broadford Road, Old Portsmouth Road and Tilthams Corner Road.

Maps of these diversions routes will be published on our website when works are underway.

Will there be advanced warning notices and letters sent out in advance of the work?

We will send letters out in advance of works starting. Advanced warning signs will be displayed and the temporary closure will only operate when the relevant traffic signs are displayed.
