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.

Cross-border taxationThe salary is taxed in Luxembourg. What changes from one country of residence to the next is how it is then accounted for at home — and which levers people forget to claim.Cross-border telework: the ceilings, country by countryHow many days can you work from home when you live in France, Belgium or Germany and are paid in Luxembourg? Two counters run in parallel, and they do not count the same thing.Where Luxembourg's cross-border workers liveLuxembourg employs more than 238,000 cross-border workers, and they are not spread evenly: a handful of towns in the first ring carry most of the flow. Here is how many residents of each one cross the border every morning.
