Sligo Town Bridges Lighting, Hyde Bridge, Markievicz Bridge and the Footbridge

AVA were successful in winning the tender to design, supply and install architectural lighting for three bridges on the Garavogue River in Sligo Town – Hyde Bridge, Markievicz Bridge and the Footbridge linking Rockwood Parade to Stephen St Car Park. Lighting of the bridges was the brainchild of the Sligo Business District Project, a collaboration between local businesses and Sligo County Council, under an InterReg Project.

Sligo Tidy Towns Committee contributed to the project. Sligo Business District Project included thirteen projects including achieving the internationally recognized tourism award, The Purple Flag, in February 2015. The bridges date from the 19th century and are protected structures. The choice of luminaires and the mounting positions were very restricted, given the protected status of Hyde Bridge and Markievicz bridge, both of which date from 19th century.

The varying water levels and the fact the river is tidal at Hyde Bridge provided additional challenges in the planning and installation stages of the project. Power management was another consideration as the lighting was required to be independently controlled, for switching on and off, but was also connected to the town lighting. The specification required lighting to be capable of colour changing.

The final solution was agreed to include mounting two ArcSKY90 luminaires on parapet walls adjoining the masonry bridges and under the pedestrian bridge. The ArkSky 90 is a high-powered outdoor fixture, the first LED-based luminaire that can be compared to a 1500W HID large-area colour washer. Colour changing is achieved using wirelessly connectivity.
