CAMDEN COUNTY - The new U.S. 54 Expressway opens to traffic today at the Lake of the Ozarks, and with that comes a traffic signal indication that is new to the Camden County area.A "Yield on Flashing Yellow Arrow" signal has been installed at the Nichols Road interchange on the new expressway. The flashing yellow arrow signal replaces the traditional "left turn yield on green ball" indication currently used in many dedicated left-turn lanes.Motorists traveling on Nichols Road who wish to access U.S. 54 by making a left turn will encounter the new signal. When motorists see the flashing yellow arrow, they should yield to oncoming vehicles and pedestrians before proceeding with caution through the intersection.After it flashes, the flashing yellow left-turn arrow then becomes the steady (non-flashing) yellow left-turn arrow. This should be treated like a standard yellow light and drivers should prepare to stop before the red light appears. Drivers will still be required to yield on a green ball when no dedicated left-turn lane is available. The goal is to improve safety by reducing the confusion experienced when the left-turn lane display appears the same as the green indication for the adjacent through lanes.Flashing yellow arrows have already been installed in Central Missouri on the state highway system in Columbia, Fulton, Jefferson City, Owensville, Tipton, Rolla and Eldon.Construction on the new U.S. 54 Expressway is not yet complete. Work continues on guard rail installation, median barrier construction, and work on the tie-in connections on both ends of the project. Motorists should be prepared for lane closures and other temporary traffic shifts when traveling through the area. A ribbon-cutting ceremony will be held in December upon the completion of the project. A map showing the new expressway and the interchanges is available at www.modot.org/central.
