Guam - You've probably seen them doing the work over the last couple of days and starting tomorrow a new traffic signal system will be fully energized at the Barrigada tri-intersection. According to Department of Public Works director Joanne Brown, the new system will optimize efficiency and asks motorists to proceed with caution when going through the intersection. 

The five-head signal light for motorists turning right onto Route 16 features a yellow and green right turn arrow in addition to the standard red, yellow and green balls.
