The proposed route of the Norwich Western Link has been removed from Ordnance Survey (OS) maps, at a time of growing doubts over whether the road will ever be built.
In 2021, the route of the road, which would connect the Northern Distributor Road to the A47 west of Norwich, was included on OS 1:250k scale maps - as a dotted line - even though it had yet to get permission or money to build it.
Campaigners against the road said at the time that it was premature for the indicative route to be included.
They complained to the OS and the 3.9-mile road's route has now been taken off its maps.
It comes amid uncertainty over whether the government will approve Norfolk County Council's business case and bankroll 85pc of the project's cost.
But OS said the removal of the route was part of a wider policy and not connected to the current situation.
A spokesman said: "OS reviewed the specification of 1:250k mapping in March 2022, which had been the only product to show proposed roads on them, when the rest of our products did not, and showed roads under construction.
"The reason for this is historical, dating back to an era when we used to make road atlases, which we no longer produce.
“The decision was made to bring all 1:250k mapping products in line with all our other products, which now only show new roads that are under construction. No products show proposed roads anymore."

Climate campaigner Andrew Boswell, who had made an official complaint about the route's inclusion, said: "I am pleased Ordnance Survey has changed its policy so that roads, like the Norwich Western Link, which may never be built, have now been removed from its products.
"The OS App now reflects the reality now - a Norfolk without the Western Link, which is what many of us wish to preserve for the future."
The county council agreed this week to wind down work on developing a planning application for the road, but leader Kay Mason Billig said the authority remains committed to the scheme.
