Äussere Baselstrasse

The AeBas/Baulos 2 works are part of the overall upgrade of the Basel – Riehen Grenze route. The section from Habermatten to Kilchgrundstrasse is in Groundwater Protection Zone 2 (2a and 2b), which means that the track area must be completely sealed. Alongside all measures to protect the ground water, necessary repairs to the road surface on Kantonstrasse are also being carried out.

A range of further works are also underway, including work on utility lines, the replacement of the BVB overhead line including pylons, installation of new furnishings at BVB stops, and rebuilding and relining the sewerage system. These works are in turn being coordinated with the road and track works. In many places, space between the building site, road traffic and tramlines is extremely limited. Access to properties must also be maintained at all times.
