At Yanpingtang Bridge in Jiaxing, RGBW floodlighting reveals the steel arches while linear LEDs trace the intersecting trusswork. CRANE provided lighting design and product supply, with DMX512-controlled scenes for regular evenings and special events.
Yanpingtang Bridge carries Provincial Highway 07 across the Yanpingtang waterway in Jiaxing, Zhejiang. Its tied-arch steel structure combines broad arch faces with intersecting truss members. After dark, the lighting reveals both the strength of the arches and the detail of the open steelwork.
CRANE's scope included lighting design and product supply. Custom RGBW floodlights illuminate the arch surfaces, while linear LEDs define selected structural edges. DMX512 brings the colour scenes together, and warm entrance lettering identifies the bridge without competing with its blue-lit steelwork.

RGBW floodlights illuminate the arch faces and selected truss members, giving the steelwork depth rather than a flat outline. Beam spread and aiming need to suit members of different widths, keeping the colour consistent while limiting stray light towards traffic.
Linear luminaires trace selected structural edges without lighting every diagonal member. Straight runs, joints and changes in direction follow the steel geometry, so the outline remains continuous across the canal and the fittings stay discreet in daylight.
DMX512 coordinates the RGBW floodlighting and linear accents. A steady blue scene defines the bridge on regular evenings, while programmed colours offer alternatives for special events. The warm entrance lettering remains distinct as the wider lighting changes.
The project photographs show the steel arch faces, intersecting members and entrance lettering at different viewing distances. The film adds elevated views of the illuminated crossing and waterway.

The blue floodlighting gives the steel arches volume; the finer linear accents keep individual members readable. The bridge name provides a separate focal point at the approach.
RGBW floodlighting for steel arch surfaces
XY Large floodlights offer directional illumination of broad steel arch faces, with model-specific optics and adjustable mounting. For a comparable bridge, select beam distribution and shielding to match the member dimensions and traffic-facing sightlines.
Straight steel truss and deck-edge outlines
RG Covered linear lights can define straight truss members and deck edges. Segment lengths and connections should follow the actual steelwork; changes in direction need planned joints and fixing details rather than bending a rigid luminaire.
Project delivery, RGBW control, steel-structure optics and specification questions.
CRANE's project scope covered lighting design and product supply. The project record lists RGBW floodlights for the arch surfaces and LED linear lights for structural outlines, with DMX512 control for coordinated scenes.
The recorded scheme uses DMX512 to coordinate the colour-changing floodlighting and linear accents. A regular blue scheme and alternative event colours allow the bridge to change appearance while retaining its recognisable steel structure.
Choose beam distributions for the widths and aiming distances of the steel members. Test colour on the actual paint finish and check beam overlap at truss connections. A representative mock-up helps identify bright patches before final aiming.
The project record specifies IP66 luminaires. Exposed installations should also consider corrosion-resistant fixings, weather-sealed connections, surge protection and service access, subject to the bridge engineer's requirements and local electrical standards.
Send the bridge elevation, arch and truss sections, permitted fixing locations, power distribution and intended colour scenes. Include the main road and waterway viewpoints, maintenance access and project timetable so the lighting proposal can be properly specified.
Share your steel arch elevations, truss details and bridge sections with CRANE. Include available fixing points, power and DMX512 requirements, viewing distances and preferred everyday or event colours. Our team can review the lighting design and product supply needs for your project.
