For months, the blinking arrow pointing motorists away from the left lane approaching the base of the Causeway in Stafford Township was nothing more than confusion for drivers who, upon getting close enough to the area, noticed both lanes of traffic were open. That changed last week, at least for a while, with cars shifting at the last minute into the left lane near Marsha Drive.

It’s unclear how long the single-lane closure will remain in effect or what lane will be closed on any given day.
