Luxembourg Road Network

By | October 31, 2022

According to wholevehicles, Luxembourg has a fairly dense road network, but most of the highways are in the south of the country. There are six highways, the A1 from Luxembourg to Trier in Germany, the A3 from Luxembourg to Metz in France, the A4 from Luxembourg to Esch-sur-Alzette, the A6 from Luxembourg to Arlon in Belgium, the A7 from Luxembourg to the north and the A13as an east-west route along the French border from Pétange to Schengen. Luxembourg has the highest density of highways in Europe with 60.3 kilometers per 1000 km². The city of Luxembourg has a half ring road. The rest of the road network consists of main roads, most of which pass through all the villages. The speed limit on highways is 130 km/h. The quality of the highways is generally excellent.

The secondary road network consists of 798 kilometers of Routes Nationales and 2,022 kilometers of Chemins Repris. North of Ettelbrück one has to use N and CR roads to travel, as there are no highways here. The main arterial road to the north is the N7. The N7 towards Sankt Vith and Vielsalm is well developed with only a few village passages and longer stretches in a 2+1 configuration. Due to the low traffic intensity on this road, the 40 km between Ettelbrück and the Belgian border at Wemperhardt can be covered fairly easily.

Since March 16, 2016, approximately 25 speed cameras have been installed in Luxembourg, mainly on the N-roads. Previously there were no fixed speed checks, but regular laser checks, which are always announced by the police. The number of road deaths in Luxembourg, at 65 deaths per million inhabitants, is higher than the European average of 55 (2012).

Luxembourg signage is a mix of French, Belgian and German signage and consistency is often hard to find. Road numbers in particular tend to be missing. On highways, the Belgian font SNV is used on older signposts; newer signposts are in Helvetica. Highways have blue signs, but exits have yellow or white signs. The arrows are Belgian, but the pre-announcement of exits, including the exit symbol, is again French. National Routesare indicated by Nx in a red shield with white letters. CR numbers are displayed in a yellow area with black lettering on white signs. Motorway numbers have a white frame with a blue area and white letters. Sometimes only the E-number is indicated and sometimes no number at all. Different types of arrows are used in both the Belgian and French style. The font is usually not in capital letters, as in France. The French cursive letters are used for local purposes.

For the signposts on the N and CR roads, people usually use their own font, which is also used on bowl signs.

Speed ​​limits

Road type Vmax

In case of precipitation there is a limit of 110 km/h on motorways. There is a limit of 90 km/h in tunnels and the western part of the A13 between Esch-sur-Alzette and Pétange is somewhat narrower and more winding and therefore limited to 110 km/h.

Luxembourg does have a road sign for motorways, but in practice they do not exist. On some parts of the N7 with 2+1 lanes, a speed limit of 110 km/h applies if two lanes are available, reduced to 90 km/h in the event of precipitation. As soon as only one lane is available in each direction, the speed limit will also be reduced to 90 km/h. The speed limit on the Schnellstrooss B7 never exceeds 90 km/h, despite the 2+1 lanes. The other Schnellstroosen B3 and B4 are located within the built-up area.

Road numbering


Luxembourg City attracts many international commuters from Belgium, Germany and France. Every day about 200,000 people cross the border to work in Luxembourg, almost half of all jobs in Luxembourg are filled by foreigners. This is increasingly causing congestion on the A1, A3 and A6 in particular. These motorways are much more prone to congestion than one would expect based on the population of Luxembourg. In 2019, a maximum speed of 90 km/h was tested on the A1 and A6 during the morning rush hour to reduce hard braking. In 2018, Luxembourg (city) was the 28th most congestion-prone city in Europe in the TomTom Traffic Index.

In 2010, there were 64 road deaths per 1 million inhabitants in Luxembourg. Compared to 2001, the country has thus achieved one of the larger percentage reductions in the European Union, a decrease of 54 percent. Despite this, road safety is slightly less than in most other countries in the region, apart from Belgium. The relatively high number of road deaths is attributed to the large number of foreign road users; this number is proportionately much higher than in other countries. In 2015, there were 64 road deaths per 1 million inhabitants, giving Luxembourg an above-average number of road deaths in the European Union. However, given the high number of foreign vehicle kilometers in Luxembourg, it does not compare well with larger countries, where foreign vehicles generally do not cover more than 5% of all vehicle kilometres.
