Everywhere in Flanders, substantial investments are being made in new cycle highways. For the construction of the F7 cycle highway between Ghent and Waregem, a missing link had to be designed in Deinze, between the Veloweg (cycle path) and the Sint-Hubertstraat, with the grade-separated crossing at Volhardingslaan being the final piece. Thanks to an integrated total approach between building technical design, architecture, process supervision and expertise on permits, SBE is the ideal party to bring this new landmark to a successful conclusion.

The route consists of 3 bicycle bridges that are in a similar design. In the starting memorandum, it was decided to allow the parapets of the bridges to function together constructively, so that a simple, slender, transparent and light design could be achieved. The bridges are constructed from a steel U-profile with perforations in the parapet that provide a playful appearance. Research was carried out into a pattern that was simple and followed the logic of the flow of forces in the flanges. It was the pinnacle of a collaboration between technique and form!

For the bicycle bridge over Volhardingslaan, the total span of 35 metres will be halved by placing a central pillar in the central reservation of the N35. With a forked, concrete column, a simple and contemporary design was once again chosen that followed the logic of the forces at flow in the pillar.

The integration of all bicycle bridges and approach ramps in the immediate surroundings presented an extra challenge, both spatially and in terms of building technology. The limited space available and its location next to the railway infrastructure required a well-considered solution that did not compromise railway operations from a stability point of view, and which took note of the view into private homes, the green character of the surroundings, and the safety and comfort of cyclists.

The interplay of the 3 bridges creates a conflict-free section of one-and-a-half kilometres of cycle highway stretching from Deinze station to Tonnestraat. Throughout this section, special attention was paid to the links between the underlying supra-local and local bicycle network. For example, the bridges over Velostraat and Sint-Hubertstraat were not initially part of the assignment. However, when looking at the underlying network, these two bicycle streets also crossed uneven ground and so the result has been a network of bicycle connections worthy of a bicycle superhighway. The result is an ambitious, well-integrated, comfortable and attractive conclusion for the F7 cycle highway.
