What is the best inventory of infrastructure


Road network (2020)

The entire road network in Germany is more than twice as long as the distance between the earth and the moon.
Divided into the individual road types, the following picture emerges:

Roads in total

approx. 830,000 km
Roads of supra-local traffic in total
Federal trunk roads
51,033 km
13,191 km
37,842 km
State and state roads86,924 km
County roads91,826 km
other roads (estimated)approx. 600,000 km

Detailed information on the length statistics of the roads used by regional traffic can be found here on the BMVI homepage in the same statistics section "Data and facts" (see below under "Additional information").

Bridges in the course of federal trunk roads (01.03.2020)
Federal highways17.976
Federal highways21.842
Tunnel in the course of federal trunk roads273
The Kochertal Bridge on the A 6 measures 185 meters from the ground to the road surface - making it the highest bridge in Germany. It towers over the tallest church tower in the world, the Ulm Minster, by 20 meters.
The oldest surviving road bridge in Germany is the Stone Bridge in Regensburg, which was built between 1135 and 1146.
The longest road tunnel is the Rennsteig Tunnel on the Thuringian Forest A 71 motorway, built from 1998 to 2003, with a length of almost 8 km.

The oldest tunnel in federal trunk roads is the Altenahr Tunnel, built between 1832 and 1834 as part of the B 267 in Altenahr.

Rail network (DBAG) (2019)

Two parallel steel rails - connected by sleepers or a concrete slab - create a track. A railway line consists of one, two or more tracks. A route can be fully or partially in operation.

Route length (operating length)
approx. 38,600 km
electrified linesapprox. 21,000 km

Waterway network (2020)

The waterways are divided into sea waterways and inland waterways. Sea waterways are the areas between the seaward boundary of the territorial sea and the coastline at medium high tide or the seaward boundary of the inland waterways. Inland waterways are the navigable waterways inside a land mass, such as larger rivers and canals.

Sea waterwaysapprox. 23,000 km2
Inland waterways
approx. 7,300 km
Sea lanesapprox. 700 km
Inland waterwaysapprox. 6,000 km
Other waterwaysapprox. 600 km

Road and rail bridges over federal waterways

Airports (2019)

In Germany, airfields are divided into airports, landing sites and glider airfields. From a statistical point of view, the main commercial airports are airports with more than 150,000 passenger units (boarding and disembarking per 100 kg of freight and mail).

Major airports
Major airports> 10 million passengers per year8
Main airports 3 - 10 million passengers per year2
Major airports <3 million passengers per year14
