ZJA collaborates with BoschSlabbers on Tjalmaweg route

 

The N206 ir. G. Tjalmaweg by ZJA architectural practice and BoschSlabbers landscape design studio serves as a vital link connecting the city of Leiden to the beaches of Katwijk aan Zee, with a mindful integration into the surrounding landscape. It acknowledges the historical significance of the region as a former boundary of the Roman Empire, while also presenting a sustainable vision for the future. Emphasizing the circular use of materials and seamless integration with the landscape, the design provides a green experience for road users and cyclists as part of the broader RijnlandRoute project aimed at enhancing accessibility and livability in the Holland Rijnland region.

 

The Tjalmaweg underscores its commitment to sustainability by minimizing the use of concrete and incorporating recycled materials. Wooden slatted walls along the sunken road are adorned with ivy, clematis, wild honeysuckle, and Virginia creeper. Adjacent areas are transformed into a green park with playgrounds and a high-speed bicycle lane. Efforts are made to reduce concrete usage, adopt sustainable timber practices, and facilitate material reuse. Biocomposite with grass fibers is employed for decking and street furniture beneath the bridges, such as the Torenvliet Bridge over the old river Rhine.

Tjalmaweg showcases sustainable construction methods

 

Promoting eco-friendly mobility, the green park creates a link between Leiden’s inner city and Katwijk aan Zee’s beaches. The park not only facilitates a safe and efficient cycle route but also offers a thoughtfully designed natural environment for recreation, interaction, and biodiversity. Featuring a diverse mix of flowers, the park incorporates furniture and insect hotels crafted from the trees that were cut down, supporting material reuse and a sustainable ecosystem. The combination of the road and adjacent green zone enhances mobility and the overall living environment.

 

Running through a UNESCO heritage area, the Tjalmaweg pays homage to the northern boundary of the ancient Roman Empire, known as the ‘Limes.’ Roman excavations, including a reconstructed section of the original Roman road and displayed oak piles, are integrated into the collaborative project between ZJA and BoschSlabbers. Road crossings are named in reference to Roman legacy, such as Praetorium Agrippinae and De Castra. The Tjalmaweg embodies a forward-thinking vision, where mobility becomes an opportunity to offer a green experience, celebrate heritage, and showcase sustainable construction methods.
