PARLIAMENTARY WRITTEN QUESTION
(10 December 2024)

Question Asked

To ask the Secretary of State for Transport, how many noise important areas of the M25 there are within the Runnymede and Weybridge constituency; and what the location is of each.

Asked by:
Dr Ben Spencer (Conservative)

Answer

The precise dates for treatment of individual sections will be determined based on regular monitoring of the condition of the carriageway. National Highways plans to give priority to treatments within the Noise Important Areas (NIA) identified by Department for Food and Rural Affairs (DEFRA) which have not already benefitted from some noise mitigation.

Next Generation Concrete Surfacing is the second phase in the treatment of the M25 concrete sections to improve the condition and reduce noise. The first phase is the reinstatement of the transverse joints between the concrete slabs to their original width and profile.

National Highways plan to undertake works in two NIAs (1286 and 1287) with the first phase starting from February 2025 until March 2026, the second phase of works will be delivered using the next generation concrete surfacing during the 2026/27 financial year with the final phase being completed between junction 9 and 11 by end of 2029.

In regard to the question on the location of NIAs, there are nine identified NIAs within Runnymede and Weybridge constituency, these are:

NIA:5858

Elmbridge

On/north of M25 at Cobham at Horsley Road overbridge. KT11 3NY.

NIA:5859

Elmbridge

On/north side of M25 taking in ’The Lodge’. 1km east of Junction 10. KT11 1PH.

NIA:1286

Runnymede

North of main railway line, over Wey Navigation and B385. KT15 3NF.

NIA:1287

Runnymede

East of Row Town, Addlestone, south of Junction 11. Includes Church Road to the north to Coombelands Farm to the south. KT15 1NF.

NIA:5887

Runnymede

Immediately north of Junction 11. Northbound carriageway only. KT16 9PA.

NIA:13841

Runnymede

Located where the A320 crosses under M25. KT16 9LQ.

NIA:5885

On/west side of M25, north of Great Cockcrow (miniature) railway. KT16 0AA.

NIA:6262

Located immediately south of Junction 12, over main railway. KT16 9NL.

NIA:1295

Runnymede & RBWM

Whole length of carriageway from Junction 12 to Junction 13. TW20 8NU.

Lastly, the concrete carriageway on the M25 within the Runnymede and Weybridge constituency remains in good structural condition and will not require full replacement within the next 30 years. During that time work may be required to individual slabs, to reinstate joints and to restore the surface texture.
