From Zurich I usually take the A1 up until Birrfeld and then hook a right onto the A3 to Basel.
The question for those who usually stay on the A1 towards Bern is what is the traffic like on a daily basis? because that may be my regular commute if we move house
I've driven up that stretch of the A1 a few times and its usually awful, but then its riddled with roadworks. The A3 in comparison is very smooth all the way from that junction to St Jakob. Also any idea when those roadworks are scheduled to complete?
