ArRiyadh Development Authority (ADA) is going to implement a bridge above the intersection of King Abdulaziz Rd. and King Abdullah Rd., during the coming days. ADA has already completed the design phase for the bridge. The bridge, after complition, is expected to raise the efficiency and smooth flow of traffic at this intersection.
The 800-meter-long bridge will consist of three lanes in each direction. It has been designed in a distinguished architectural manner that takes into account the aesthetic aspects of the road and harmony with the surrounding environment. Movements will be allowed under the bridge in a way that increases the efficiency of the intersection.
I am pleased to inform you that IESNA have released their latest ANSI/IES RP-8-14 Roadway Lighting. I am listed as one of the Advisory Member where I was able to share lighting design techniques and some best practices that we do here in the region for Roadway Lighting application. We have been exchanging ideas on several points for over two years and casting votes regarding topics with disputes and this is now our fruit of labor.
