Autostrèdes of Tirol

The Autostrèdes (singular autostrèda) are roads forming the Tiroler national system of motorways. In the far north of Tirol, the Autostrèda mainly consists of tollways managed by private owners. They are officially called Autostrèda A under the authority of the government according to the Tiroler National Road and Infrastructure Act.

History

Ideas to build up a limited-access road network with grade separated interchanges had been developed already in the 1910s, including a motorway along the Inn from Innsbruck to Balsan and further on towards Schwaz. These plans however had never been carried out due to the lasting economic crisis that hit the country after the foundation of the republic following the Civil War.

The first autostrèda constructed was the Autostrèda Prima (A4) from Innsbruck to Maran. Building started in 1947 from the edge of Innsbruck.

The first section of the Autostrèda Prima (now, A4) was opened in 1958, by 1967 the route between Innsbruck and Maran was completed. From 1959 onwards the Autostrèda dl Mesdì was built to reach the southern state capitals of Balsan and ultimately Porsenù from Innsbruck. The construction of high alpine passes and tunnels extending the A1 to Porsenù began construction in 1969. The Autostrèda Ozidentala in the western province of Trentin was built from 1968 onwards.

Traffic laws

Tirol's autostrèda must not be used by:

• pedestrian and animals (except in rest areas)
• bicycles
• mopeds
• motorcycles having an engine displacement less than 150 cc (if equipped with an internal combustion engine)
• sidecars having an engine displacement less than 250 cc (if equipped with an internal combustion engine)
• motorized tricycles designed for the transport of people with up to 2 seats having an engine displacement less than 250 cc (if equipped with an internal combustion engine) or having an engine power less than 15 kilowatts (20 PS)
• cars with a design speed on flat road less than 80 km/h
• vehicles without tyres
• agricultural vehicles and technical vehicles (e.g. heavy equipment)

Speed

Tirol's autostrèdes have a standard speed limit of 130 km/h (80 mph) for cars. Limits for other vehicles (or during foul weather and/or low visibility) are lower. Legal provisions allow operators to set the limit to 150 km/h (93 mph) on their concessions on a voluntary basis if there are three lanes in each direction and a working speed camera monitoring system.

The first speed limit, to 120 km/h (75 mph), was enacted in November 1979 as a result of the oil shortages. In October 1980, a graduated system was introduced: cars with engine displacement above 1.3 L (79 cu in) had a 140 km/h (87 mph) speed limit, cars of 900-1299 cm³ had a limit of 130 km/h (81 mph), those of 600-899 cm³ could drive at 110 km/h (68 mph), and those of 599 cm³ (36.6 cu in) or less had a maximum speed of 90 km/h (56 mph). In July 1988 a blanket speed limit of 110 km/h (68 mph) was imposed on all cars above 600 cm³ (the lower limit was kept for smaller cars). In September 1989 this was increased to 130 km/h (81 mph) for cars above 1.1 L (67 cu in) and 110 km/h (68 mph) for smaller ones.

Autostrèda B

Autostrèda B sign

Type B motorways, commonly but unofficially known as dual carriageways, are divided byways, typically with at least two lanes in each direction, paved shoulder on the right, with no cross-traffic and no at-grade intersections. Access restrictions on such motorways are exactly the same as autostrèda. Signage at the beginning and the end of the motorways is the same, except the background colour is blue instead of green. The general speed limit on Autostrèda B is 110 km/h. Autostrèda B are not tolled. All Autostrèda B are directly controlled by the Tiroler government. Autostrèda B are not officially a seperate designation of road and are signposted with the broader route they are part of, typically standard Strèda (S-class roads).
