How tall is your camper?
60 725 official low bridges, underpasses and tunnels from the national road registers of six countries. Slide to your vehicle's height: the red ones are the ones you cannot pass.
Your height, your low bridges
20 320 official clearances are lower than 3.2 m.
- France 17 154
- Netherlands 2 213
- Austria 318
- Sweden 307
- Norway 169
- Finland 159
The 3.5-tonne line
A motorhome over 3.5 t may not take a road signed for 3.5 t. The same registers hold 29 669 such limits — most of them in France, on village streets and small bridges.
Where nobody knows from official data
- Germany: No national register of road limits; cities publish signs one by one, and the ones we checked carry almost no height signs (Hamburg: 1 in 208 118 signs).
- Poland: The national register was abolished by law in 2021.
- Spain: The national road layer has no clearance attribute.
- Italy: Only province-by-province files for exceptional transport.
- United Kingdom: Low-bridge data is not published as an open register; Network Rail's bridge list has no open reuse terms.
- Denmark, Czechia, Belgium (Flanders): Registers exist; we are getting access (an account, a licence answer).

One point per structure: a stretch of road with a limit counts once; Dutch signs, one each way, count once per structure. Walking and cycling paths are left out, and so are French tunnels, whose register line runs under the street above them (the tunnels' heights are on the map itself). Heights from 1.5 to 4.6 m; weights of 3.5 t or less.
Questions and answers
Answered from this page's own data, as of 26 October 2026.
Does the planner route around these?
Yes. Enter your vehicle's height, width, weight and length and the route goes round every official limit it cannot pass in these six countries; one that no road avoids is named on the plan with its source and date, before you leave.
Why does the count jump at 3.1 m?
Many French clearances are signed at exactly 3.0 m. A vehicle of 3.0 m passes a 3.0 m sign; at 3.1 m it no longer does.
Is a clearance the same as a sign?
Mostly. Norway and Sweden also give the measured height where nothing is signed; the Netherlands lists the signs themselves, one per structure here. Walking and cycling underpasses are left out — they are not on a road you drive.
What about the countries in grey?
There is no open national register we can read there. Navigation companies sell their own surveys; we only use official data we can name, so the planner says plainly when a road's height is unknown.
