Usage tips
Compound word
The word is made up of 'Ein-', '-bahn-', and '-strasse'. It literally describes a street that has only one lane or direction.
EXAMPLE

The traffic routing was changed; this street is now a one-way street.
Regional spelling

EXAMPLE
In Zürich gibt es viele enge Einbahnstrassen in der Altstadt.
In Zurich, there are many narrow one-way streets in the old town.
Movement and location
The preposition 'in' is used differently: 'in eine Einbahnstrasse fahren' (to drive into a one-way street, accusative) describes movement into it, while 'in der Einbahnstrasse sein' (to be in the one-way street, dative) describes location.
EXAMPLE
Er ist aus Versehen in die falsche Richtung in die Einbahnstrasse gefahren.
He accidentally drove the wrong way into the one-way street.
Context clue
You can recognize the figurative meaning from the context. If it is not about traffic but about abstract topics such as a relationship, a discussion, or a financial situation, the figurative meaning is intended.
EXAMPLE
Die Kommunikation mit ihm ist eine Einbahnstrasse; er hört nie zu.
Communication with him is a one-way street; he never listens.

Einbahnstrasse vs Sackgasse
dead end
'Sackgasse' and 'Einbahnstrasse' both have to do with streets and direction, but they do not mean the same thing. A 'Sackgasse' (dead-end street) is closed at the end; you cannot go any farther and have to turn around. An 'Einbahnstrasse' (one-way street) may only be driven on in one direction, but it does not have to end. Figuratively, both can also describe a difficult situation. 'Sackgasse' emphasizes that there is no way out or no progress. 'Einbahnstrasse' emphasizes that something only goes in one direction and hardly allows any turning back.
Einbahnstrasse
Diese Einbahnstrasse darfst du nur von der anderen Seite aus befahren.
You can only enter this one-way street from the other side.
Sackgasse
Wir sind in eine Sackgasse gefahren und mussten am Ende wenden.
We drove into a dead-end street and had to turn around at the end.
