The perfect example of one lane marked but treated as two lanes is this stretch of Rt. 3A in Burlington between Mall Road and Rt. 62 (Wilmington St.). At each signalized intersection along the stretch, marked with solid white line as two lanes. However, outside them no dashed white lines to be found. Makes for quite the surprise if you’re unfamiliar with the practice along this road!View attachment 26712View attachment 26713View attachment 26714
Legally one, but treated as two in most places. But that's about to change.
