The longest open stretch
In one go without a limit you can drive up to 26 km on the A63 (per carriageway) – the longest continuous derestricted section of this Autobahn. On the interactive map you can follow exactly where the limit drops and where it returns.
Enter start and destination and see how much of your drive is open – and what that means for travel time.
How the figures are produced
The basis is our own analysis of the freely available OpenStreetMap data. For every section of the A63 we check whether a speed limit is recorded and sum the length by category. “No limit recorded” means the tag is missing in the data – which is not the same as open road. This is a data-based analysis, not an official survey.
Frequently asked questions
How much of the A63 has no speed limit?
49.5 km of the total 70.6 km, i.e. 70.1%. The remaining 21.1 km have a fixed limit, are gantry-controlled or have no recorded limit.
How long is the longest open stretch on the A63?
Up to 26 km in one go – the longest continuous derestricted section on the A63 (per carriageway).
Is the A63 completely derestricted?
No. While 70.1% is open, interchanges, junctions and roadworks carry a limit. No Autobahn is fully derestricted.
