2015: 3Land space use concept

In November 2013, the LIN consultancy of Berlin and Paris was invited to develop a 3Land space use concept. This concept presents various opportunities for development. It treats the development zone as a single entity and determines the locations at which particular uses are the most rational. The focus here is on the themes of nature and landscape, mobility, uses and urban development.

The outcome of the study was presented in 2015 at a travelling exhibition in the three cities of Basel, Weil am Rhein and Huningue. The exhibition was accompanied by numerous events in which the space use concept was discussed with interested members of the public. In a survey, visitors had an opportunity to express their views and make suggestions about the concept. Evaluation of the survey forms part of the complete documentation about the 3Land space use concept.


Some extracts from the LIN consultancy proposals:

1. Rhine residential space – connections and centre

  • All the riverbank areas will be accessible to pedestrians and cyclists
  • New leisure uses will be created on the water
  • The Canal de Huningue and Wiese Rural Park will be linked more directly to the Rhine
  • The aim is to achieve better networking of the existing green spaces

2. Three new multifunctional landscape areas

In Huningue

The former quarry could be redeveloped as an urban park.

In Weil am Rhein

A new green corridor could be created along the border and below the motorway.

In Basel

The former rail track area could be used as a central leisure space.

As the background conditions and political objectives have not yet been clarified, the space use concept has three potential scenarios: park scenario, old course of the Rhine scenario and peninsula scenario. All three scenarios comprise the same essential core elements: an extensive leisure space with and without water courses or basins in the existing rail track area, a park at the Southern approach to Klybeck wharf, green  Rhine riverbanks open to the public and good links to the existing district and neighbouring 3Land.

3. Three new bridges

Three new bridges will provide a better link within the development area. No new motor vehicle bridges are proposed; instead there will be bridges for pedestrians and cyclists and another for public transport:

CH-FR link: linking Basel to Huningue across the Rhine (essentially for local public transport, pedestrians and cyclists) (see transport study [Link])

CH-DE link: link to the three-country triangle from Basel to Weil am Rhein/Friedlingen (for pedestrians and cyclists))

CH-CH link: a bridge for pedestrians and cyclists creating a link with the newly inaugurated Rhine riverbank on the St. Johann and Klybeck side. The location of the bridge will depend largely on the design of the new harbour district (see scenarios).

4. X-scheme for mobility

 Ideas for the development and planning of crossborder mobility and crossborder transport.

A bridge between Switzerland and France is planned (at Klybeck), mainly for public transport, pedestrian and cycle traffic.

Multimodal corridors are to be created in parallel with the riverbank. The nodal point is located at the bridge between CH and FR. Existing tram lines will be extended.

The riverbank areas are closed to motor vehicles.

5. Three complementary development programmes

Urban Vis-à-Vis between Huningue and Basel with the focus on living and working (Huningue: education campus, new industries/Basel: residential and mixed uses)

Vis-à-Vis across the Rhine between Huningue and Weil am Rhein(Weil am Rhein: residential, leisure uses/Huningue: residential, leisure uses, hotel)

Huningue laboratory campus (between the Rhine and former quarry): education (focus on languages), research, new industries

6. Dialogue/Feedback/Talking to one another

The 3Land project presents a great challenge because it is designed to take account of today’s expectations while at the same time anticipating tomorrow’s needs. That is why IBA Basel 2020 and the three cities of Weil am Rhein, Huningue and Basel are particularly keen to open a dialogue with the population, landowners and other actors about this cross-generational space use planning.

A survey and accompanying events were organised during the exhibition of the 3Land space use concept in Weil am Rhein, Basel and Huningue. Feedback from the public was assessed and has been published in a separate brochure.

Events accompanying the exhibition of the 3Land space use concept in the three cities of Weil am Rhein, Huningue and Basel proved a great success. All the events were fully booked.

2018: Transport study

The 3Land development is intended to create residential space and workplaces for some 20,000 persons. To facilitate a high quality of life and living in the 3Land, urban estates and transport facilities will be closely coordinated. The planning partners give priority to the development of pedestrian, cycle and public transport.

A trinational transport study was completed in 2018. The study concludes that high value and sustainable development of the 3Land is perfectly feasible and allows sufficient freedom of action for the future. The study highlights the need for intensive development of the existing infrastructure for this purpose. Strengthening and linking up the existing nodal points is necessary – especially in public transport.

Infrastructures are also planned for motor traffic, including new park and ride facilities.

A new Rhine Bridge between Huningue and Basel for public transport as well as pedestrian and cycle traffic is the central feature. It will permit the best possible access to the development zones and new public spaces. Short distances and networking of the districts with all the countries’ nodal points are key contributory factors to attractive public transport.

The study was drawn up by an inter-disciplinary team (Kontextplan AG together with van de Wetering Urban Planning Workshop, Rapp Trans AG and Rapp Infra AG).


2019: Criteria catalogue – Certification « nachhaltiges 3Land durable »

The criteria catalogue defines the background to the creation and introduction of a sustainable development and construction certificate:

“Sustainable 3LAND durable”: a certificate with added value

The “Sustainable 3LAND durable” certificate is issued jointly by the three municipalities of Basel (CH), Weil am Rhein (D) and Huningue (F). This certificate is awarded to sites, residential and business buildings as well as green and leisure spaces in the 3Land development area which respect sustainable construction guidelines and aim to achieve six defined strategic objectives. For the first time, a label has been developed that is directed at private and public investors, landowners in the three countries and the three participating cities.

The certificate is innovative, crossborder and designed to exceed existing country-specific standards.

2020: Leisure space and nature conservation concept

In a nature and leisure concept, the landscape is placed in a trinational context, gaps are closed, and initial measures shown – a topic that was frequently mentioned by people living in the three-country triangle when a survey was organised in the summer of 2015. Lines of action for future procedures were proposed in which integrated attention is to be paid to nature conservation and leisure spaces, coordinated with future urban development.

Based on an analysis of the existing natural and leisure spaces in the 3Land, these results are converted into a concept and initial measures then defined. The focus is on the River Rhine and new links and access facilities are created, together with new leisure spaces for a variety of uses and a self-contained biotope system.

The leisure space and nature conservation concept was signed by the 3Land’s local elected officials, reaffirming their commitment to reshaping and creating public green spaces within the project perimeter.


Vis-à-Vis Weil am Rhein/Huningue

The cities of Weil am Rhein and Huningue are united by one of the oldest Franco-German urban partnerships which even predates the signing of the Elysée Treaty. The construction and inauguration of the three countries bridge in 2007 was an important milestone for the partnership. The bridge’s great success story is now to be continued with the joint restructuring of the Rhine riverbank. The Rhine bank has real potential for a range of uses by both towns. For a long time, harbour operations prevented public access to the riverbank. Restructuring now brings new opportunities. The riverbank on both sides of the Rhine is to be newly laid out and opened up. What is more, an architectonically attractive urban district networked by the new route is to be created in Huningue. On the Weil side, the adjoining Rhine Park will be redesigned and substantially extended. The restructured Rhine riverbanks will also be linked up to the existing cycle track (voie verte) laid out along the Rhine and stretching from Basel inner city to Huningue.
