In the 20th century, the walnut trees that gave the historic Walnut Bridge its name were tragically lost to disease, leaving the area without the charm and natural ambience that once made it a beloved gathering spot for local communities to relax and socialize. Over time, this loss diminished the bridge's role as a central hub of activity and connection.

Recognising the need for revitalisation, Guildford Borough Council undertook plans to update Walnut Bridge as part of a broader initiative aimed at creating safer and more accessible routes throughout the town. This project was particularly focused on improving connections between key areas such as the train station and the high street, ensuring better integration for residents and visitors alike.

The vision for the new bridge included a wider footpath to accommodate pedestrians, a designated two-way cycle lane to support sustainable travel, and full accessibility for individuals with reduced mobility. Moreover, effective lighting was deemed essential to ensure the bridge could be safely and comfortably used at all times of day. It was at this critical juncture that DFL stepped in to bring the council's vision to life...

Design and engineering consultancy Arcadis asked us to create a bridge lighting design, that worked for the difficult area the bridge was situated in. So, we took their concept and created a 3D lighting and electrical design in DIALux, which painted an accurate picture of what the lighting would look like at various times of the day.

Our lighting scheme needed to overcome numerous challenges. For example, as Guus Ketelings, lead designer on this project, explains, ‘One key objective for the visual was to achieve a uniform lighting scheme so that the area leading up to the bridge felt comfortable and spacious with a modern, 21st-century feeling (similar to the style of the bridge)’.

We also needed to protect nearby wildlife that could be disturbed by obtrusive bridge lighting whilst keeping it away from the towpath and river itself. Plus, it was our job to ensure everything had a sufficient electrical supply. Basically, we had our work cut out. But we got it done!

In the end, we opted for bespoke tilted light stacks, which were designed by DW Windsor. This unusual lighting helped to illuminate key elements of the area, along with a lit up handrail on the bridge itself. We also kept all lighting to a low level, both in terms of intensity and height, to ensure sufficient visibility without causing a nuisance.

The final build is almost complete and we’re proud to have been a part of the redesign of this cherished area of Guildford’s heritage. The area still retains an element of brutalism but with a modern twist on bridge lighting. What an honour to play a part in the area’s future!
