A decision will be made today on how to plug a £30m funding gap in the cost for the controversial Norwich Northern Distributor Road.

It emerged earlier this month that the cost of the 12.5-mile road, from the A47 at Postwick to the A1067 Fakenham Road, had soared from £148.5m to £178.5m.

A deal has been tentatively forged which would close the funding gap. The government has told Norfolk County Council it is prepared to contribute £10m, the New Anglia Local Enterprise Partnership will consider putting up £10m, which would leave the council to find the final £10m.

Norfolk's county councillors will today be asked, at an extraordinary meeting of the full council, to agree how to provide that £10m. Officers are recommending £2m is taken from reserves and from the highways budget for the next four years, although councillors could decide to borrow the cash - or not to provide it at all.

The LEP board will consider whether to provide its share at a meeting next week.
