"Red Route"
The “Pfaffenstein Tunnel” is the bottleneck on the A93. Various traffic jams (e.g. the so-called “mega-traffic jam” on October 18, 2002) have shown this more than clearly. That is why the "Red Route" has been designated since April 2004, which represents a large bypass for the Regensburg area. The "Red Route" is marked by a red point (in the north direction) or a red circle (in the south direction) on the various pre-signposts on the motorway and on further roads. It has the following course in both directions:
- AK Regensburg - AS Beratzhausen - R 11 - St 2165 - St 2235 - Bypass Burglengenfeld - B 15 - AS Ponholz.
The route is "activated" at the instigation of the police in traffic jams, which are likely to drag on for more than 1 ½ hours, via traffic announcements. Compare also "Blue Route" on the federal road 20 .
construction
The tunnel was built using shotcrete . Difficulties arose during construction due to the irregular course of layers with different strengths. There were two major breaches. The tunnel tubes have a cross-sectional area of 86 m² each. This increases to 139 m² to 149 m² at the south portal.
