Our recent investigations have established there are a number of utility services in the vicinity of North Hall Road, including Openreach cables and water main running alongside the river.  Gigaclear cables have been identified in the adjacent carriageway and we are aware of a major pipeline in the area. This information will support our future investigations, as well as design and construction works as the apparatus will need to be avoided to protect supplies to surrounding properties, as well as the safety of our workforce.

About the scheme

Along North Hall Road, Little Henham, there is a length of the River Cam that runs parallel with the carriageway. This carriageway is supported by a retaining wall and embankment. An inspection identified that a section of the retaining wall had suffered from significant under-scouring and partial collapse.

The retaining wall is approximately 40 metres, however beyond the wall is an embankment of some 100-120 metres in length. 

Due to the condition of the wall and close proximity to the carriageway edge and the width of the existing road, an emergency road closure was implemented in July 2020 on the section of road affected.

The works

Investigations to date have revealed that the issue with the embankment and retaining wall are more complex and the length of wall requiring remedial works is longer than first anticipated.  

The retaining wall has been heavily under-scoured and parts have either collapsed or slumped.  The embankment has also suffered from severe scouring.
We are preparing a 'design and build' contract for tender which will encompass all the stages necessary to re-build the collapsed wall. This project is being commissioned for design in the 2021/22 financial year. 

How it may affect you

The current road closure will remain in place until further notice. We fully appreciate that this temporary road closure will be an inconvenience to those who regularly use the route however we must put public safety first.

An alternative route is available via North Hall Road, Ugley Road, London Road B1383, North Hall Road.  This diversion route has been selected to avoid the low railway line bridge located on North Hall Road (located south of the closure) which has a height restriction of 12ft.

Access is available to pedestrians and dismounted cyclists.

Our programme plans may be subject to change if unexpected issues rise.
