The Baltic countries of Estonia, Latvia and Lithuania have opened their borders to one another, creating a coronavirus "travel bubble".
From midnight on Thursday, citizens and residents can move freely between the three EU nations.
Anybody arriving from outside the zone however must self-isolate for 14 days.
This is the first "travel bubble" in Europe since nations began shutting their borders earlier this year in response to the coronavirus outbreak.
European Union officials are now trying to encourage other countries to end restrictions on movement as concerns grow about the economic impact of the lockdown. The Baltic states are the three poorest nations in the eurozone, and expect their economies to shrink by up to 8% this year.
In a statement, Lithuania's Prime Minister Saulius Skvernelis called the move "an opportunity for businesses to reopen, and a glimmer of hope for the people that life is getting back to normal".
Under the new rules, anyone who has not travelled outside the Baltic states in the past two weeks, is not infected, and has not been in contact with somebody who has tested positive may travel freely to the other nations.
The sparsely populated Baltic states have not been as badly affected by the pandemic as some of their European neighbours.
There are fewer than 150 recorded deaths between the three nations, according to data collected by Johns Hopkins University. Official national data shows very small numbers of new infections, and the three governments have already begun loosening lockdown measures brought in to contain the virus's spread.
