LTP was appointed as specialist lighting sub-contractors and consultants to SH Structures, who fabricated the 32.6m bright yellow single span steel bridge that now crosses the A40 in Acton, London W3. It was part of a major project by Transport For London (TFL) that also replaced the two 1920's Western Avenue road bridges in this area, and was conceived and designed by architects Grimshaws and consulting engineers/architects Hyder Consulting. The main contractors for construction and delivery of the project were Carillion.
The LTP team was led by Terry Reeves and Jonathan Adkins, both of whom have considerable experience in lighting bridges. Reeves comments, "Bridges always require special and individual considerations when key-lighting, involving plenty of creative and practical thought."
The lighting brief for the main bridge span included producing an environmentally friendly, unobtrusive, elegant and safe lighting solution emitting the correct levels of luminosity to meet BS design standards and comply to all the public health & safety regulations.
LTP specified 70 units of the new 400 mm white BWS 520 4 Watt inset handrail LED fixtures from Phillips, 35 of which are used on each side of the structure which straddles the road diagonally. The lighting units also had to be tough, durable and vandal-proof, with no exposed casings. The essential effect is to neatly key-light the bridge decks for the public without causing any glare or unnecessary distraction to passing motorists below.
