Hochkönig Road
The Hochkönig Road ( or, in Tyrol, Hochkönigstraße), – the B 164 – is a state road (Landesstraße) in Austria. It has a length of . Beginning in Bischofshofen in the Salzach valley, it runs initially between the Hochkönig and Dienten Mountains along the Dienten Saddle () and on into the valley of the  Saalach to Saalfelden am Steinernen Meer. On the far side of the Saalach the road runs into the Leoganger Tal between the Leoganger Steinberge and the Loferer Steinberge to the north and the Kitzbühel Alps to the south via Leogang up to the Grießen Pass (), and via Fieberbrunn downhill again into the valley of the Kitzbühler Ache to St. Johann in Tirol. On the last section the road runs parallel to the Salzburg-Tyrol Railway. History 

Since 1948 three sections of the present-day Hochkönig Road in the state of Salzburg have been classified as Class II state highways ( Landesstraßen):
The  Mühlbach Road (Mühlbacher Straße) between Bischofshofen and Mühlbach
The  Alm Road (Almer Straße) between Alm and Saalfelden
The  long Leogang Road (Leoganger Straße) between Saalfelden and Leogang

With effect from 1 July 1962 the last two roads were extended:
The Alm Road was lengthened by  as far as Hinterthal. The Leogang Road was lengthened by  as far as the Tyrolean state border at the Grießen Pass. The middle section between Mühlbach and Hinterthal wurde was declared a Konkurrenzstraße (literally "competitive road") by the state act of 11 April 1962. In Austrian legal language Konkurrenz means joint financing of a project by various institutions, of which each takes on a legally defined percentage of the maintenance costs. In this case the shares were:
the State of Salzburg 65.00%
the municipality of Alm 8.00%
the municipality of Bischofshofen 2.25%
the municipality of Dienten am Hochkönig 8.00%
the municipality of Mühlbach am Hochkönig 8.00%
the municipality of Saalfelden 3.75%
the Austrian State Forests 5.00 %

The Hochkönig Road has been part of the network of federal highways (Bundestrassen) in Austria since 1 Jan 1973. Traffic restrictions
