European route E 67 is an E-road running from Prague in the Czech Republic to Estonia and by ferry to Finland.

Along the Via Baltica highway, the stretch of European route E67 between Warsaw and Tallinn, a 5G mobile network will be built in order to facilitate self-driving vehicles and expand opportunities for freight carriers.

Most controversial was the Augustów bypass, which would take the route through the wetlands of the Rospuda Valley, the last area of its kind remaining in Europe,[citation needed] and an area protected by EU law as part of the European Natura 2000 Network.

In July 2007 Polish Prime Minister Jarosław Kaczyński halted work on the bypass after the European Commission applied for an immediate injunction.
