The new bridge across the Forth estuary does not feature on Google Maps just hours ahead of its official opening.
Users are unable to find the £1.35bn Queensferry Crossing, which opens to traffic on Wednesday morning after six years of construction.
Google Maps shows the existing Forth Road Bridge and the iconic 19th Century Forth Bridge, but not the new crossing.
Google said it was working to update Maps as soon as possible, once the bridge is officially opened.
Meanwhile, the Ordnance Survey confirmed that the crossing was on its OS MasterMap database.
It said the database was updated 10,000 times a day by OS surveyors.
The new bridge between the north of Edinburgh and Fife will take most of the 24 million vehicle journeys a year that currently use the ailing Forth Road Bridge.
The existing suspension bridge will be adapted to be used by lighter traffic such as bicycles, pedestrians and public transport.
On Monday night, First Minister Nicola Sturgeon switched on the lights and a projection was beamed over the new Queensferry Crossing to mark a week of celebrations around its opening.
