Also, this, detailing Irish haulage and shipping changes so far and reminding us all that things are about to get even more complicated:
In the week to 22 February, freight volumes on Stena Line ferries from the Republic of Ireland to GB were down 49% compared to the same week last year, while volumes going directly to France were up 102%.
The direct sea routes to France are slightly slower and more expensive than crossing the Irish Sea and then driving south through Wales and England to cross the Channel between Dover and Calais.
But going direct avoids the new post-Brexit checks and paperwork associated with the Dover-Calais route, and the Stena Line figures are reflected across the industry. It means lorries never leave the single market, and they avoid new customs formalities.
Stena has started a new route from Dublin to Cherbourg to go alongside its existing route from Rosslare to Cherbourg. It now has 14 weekly crossings between Ireland and the continent compared to six last year.
Another new route is run by DFDS Seaways from Rosslare to Dunkirk, close to Calais. It provides easy access into the heart of Europe.
DFDS says the service, which runs six times a week and takes just under 24 hours, is almost always oversubscribed. An announcement of additional sailings is expected shortly.
"The new routes are booming," says Glenn Carr, the general manager of Rosslare Europort, "for both accompanied (by a driver) and unaccompanied units."
"At one stage in January freight trade to the UK was down 70%. It's picked up since then, but now the week-on-week increase is only incremental."
Overall, there are currently 36 sailings per week from Ireland to Northern France, up from 12 a year ago. And Rosslare's freight traffic with mainland Europe rose by a remarkable 446% in January, compared to 2020.
"Businesses have just made strategic decisions to move their trade," Mr Carr says.
Irish haulage companies have noticed the change.
"We're exporting about 150 to 200 loads to France every week," says Chris Smyth, the commercial director of Perennial Freight in Wexford, just up the coast from Rosslare...
...For hauliers who want to continue using the land bridge, things are about to get more complicated.
At the moment, they only have to face new export bureaucracy when they leave Britain and arrive in France.
Soon (in April and then more widely in July) they will be facing similar import measures when they arrive in Britain from Ireland, making the post-Brexit border procedures on the land bridge even more cumbersome.
The Irish government has, says Minister of State for Transport Hildegarde Naughton, been "urging business using the GB land bridge to switch to direct routes to avoid the new control regimes."
She says there has been "an unprecedented response from the shipping industry" to increase capacity.
