Bottenwil AO K 317, Vorstattstrasse (AG)


Outside of town, between village exit of Bottenwil and cantonal border between Aargau and Lucerne, the K317 was being repaired over a length of 450 meters. In addition, the seepage line was completely replaced in the entire section. This included two diversions into the Uerke river with a total length of approximately 230 metres. Furthermore, the edge trims were replaced, the existing retaining wall rehabilitated and a seepage bed with overflow shafts constructed in sections.



Special features of this project were the deep seepage pipes and road crossings (up to 3.0 m below ground level) as well as the complex soil protection measures following out of drains’ rehabilitation.



Go Bau AG was commissioned with the planning over all SIA phases 31 to 53.
