NYCDOT's 9th Avenue bike lane facility solved the tricky issue of how to design intersections of the protected bike path and cross-streets, to ensure that cyclists and motorists could see each other and left-turning vehicles did not endanger cyclists who were continuing straight ahead. NYCDOT addressed these issues by providing special signals for cyclists and left-turn bays for drivers with a separate signal phase, allowing them to cross the path when cyclists are stopped.
