Our 2013 Pawtucket River Bridge project is featured on the cover of this month's LD+A Magazine! LD+A is the house publication of The Illuminating Engineering Society of North America.
The article can be found on pages 40-43 of the September 2014 issue and was written by Samantha Schwirck. The lighting design for the Pawtucket River Bridge included 8 fixture types - either metal halide or LED. Details of the programmable LED color-changing system are described in the article along with the full scale mock-up test that was used to determine the LED's durability. The working model of the bridge pylon (see below photo) sat outside of town hall for 2 years and was exposed to all types of New England weather. The test even allowed the manufacturer to correct an issue in some of the LED fixtures that was allowing condensation to build inside!
ALD is honored to be included in LD+A and to have worked on such a beautiful and successful project.
