Autobahn (Motorway) Directory
Since 1969, the Federal Highway Research Institute has maintained current information on motorways in cooperation with the Federal Ministry of Transport, Building and Urban Development as well as road construction authorities. This information is updated regularly and made available according to the trunk road ordinance §1 (5) in an Autobahn Directory (AVERZ). The underlying database is also evaluated for the purpose of construction site administration via the Internet.
The Autobahn Directory describes every motorway in terms of its routing. The header contains all long-distance destinations as orientation. Displayed above the directional details are the inbound and outbound destinations for each pair of terminal points.
