Impact for car travelers on A 13 Brenner motorway (Bavaria - Innsbruck - Italy)

Travelers shall consider train connections.

No reason to panic. For a strech of about 2.5km (1.5mi) two lanes have to merge into one. When there is very heavy traffic, a second (provisional) lane will be opened temporarily.

No panic at all but the Brenner is known as affine for traffic jams and that already without a large construction.

Article with background:
"With queues reaching 70km, a solution to the Brenner pass bottleneck continues to escape EU governments and authorities. Discussions may no longer be enough; the EU Commission should open its legal toolbox."

... but the Brenner is known as affine for traffic jams ...

This is a hot political topic, not to be discussed in this forum.

I'm not entering into politics but I can relate a 2 hour delay on a journey into Italy using the high bridge at Brenner. It didn't help that somebody had spilled a caravan near the bottom of the hill. Other trips have been reliable but sometimes slow in the area. There is a McDonalds on the service area just south of the Europa bridge at Schönberg with a great view. I've stopped there a few times when tired of the traffic.
