Living cross-border
Living in France, Belgium or Germany while working in Luxembourg: rents cut in half or by two-thirds, but a daily commute that can ruin everything. Here are the real numbers, corridor by corridor.
🇫🇷 A31 / A3 — Metz · Thionville → Luxembourg
A31 (FR) → A3 (LU) · 131 260
+25 to +45 min at peak — the Greater Region's busiest corridor (over 100,000 vehicles/day at the Zoufftgen border).
Line 90: Thionville–Luxembourg in 23 min, Metz in ~50 min. Packed at rush hour, TER/CFL capacity being added gradually.
The A31bis project moves slowly; meanwhile the P+R (Thionville, Hettange, Frisange) + train combo remains the best workaround.
🇧🇪 A6 / E25 — Arlon · Pays-Haut → Luxembourg
E411/E25 (BE) → A6 (LU) · 53 750
+15 to +30 min at peak, recurring slowdowns between Sterpenich and the Gasperich interchange.
Arlon–Luxembourg line: ~38 min, half-hourly at peak. Rodange serves the Longwy/Athus basin.
The most predictable corridor of the three neighbours; the Kleinbettingen and Rodange P+Rs fill up early.
🇩🇪 A64 / A1 — Trier → Luxembourg
A64 (DE) → A1 (LU) · 53 380
+15 to +25 min at peak, bottleneck at the Wasserbillig border bridge and on the Trier bypass.
Line 30: Trier–Luxembourg in ~50 min via Wasserbillig, hourly with peak extras.
Perl and Schengen often switch via the A13 (Frisange) — watch both routes.
🇱🇺 A7 / N7 — Nordstad · Ardennes → Luxembourg
A7 (tunnel Gousselerbierg) → Kirchberg
+10 to +15 min at peak approaching Kirchberg; the A7 stays the most fluid axis.
Line 10: Ettelbruck in 28 min, Clervaux ~52 min. Frequent, reliable, free like the whole network.
Public transport is 100% free in Luxembourg since 2020 — the only cost of an internal commute is time.
