The A47 Alliance wants more than £100 million spent on the road that’s a major artery across Norfolk and Cambridgeshire.
The alliance presented its brochure, Gateway for Growth, to roads minister Robert Goodwill on Tuesday.
Made-up of MPs, councillors and interested parties, the Alliance wants £127m spent on the route over the next three years – including £30m for the Hardwick, Saddlbow and Pullover interchanges in King’s Lynn.
The group also estimates that economic benefits as a result of improving the road could see 750 new jobs in Lynn and 1,500 in Wisbech if the section bypassing the town was also improved.
Alliance members, led by chairman David Harrison, travelled to London to meet Mr Goodwill and outline the case for investment.
West Norfolk councillor and Alliance deputy chairman Vivienne Spikings said she was pushing hard for improvements to the road this side of the county.
“We need improvements to the Hardwick junction and with a planning application going in for more than 1,000 new homes in that area it is really important,” she said.
“We have to address all these pinch-points across more than 100 miles of road including the A12 at Lowestoft,” she added.
The route is on a shortlist of six subject to a government detailed business plan.
