HANOVER — On Wednesday, the intersection of Etna Road with Greensboro Road and Great Hollow Road is scheduled to become an all-way stop.

The New Hampshire Department of Transportation plans to install additional stop signs for the Greensboro Road southbound approach to Etna Road and the Great Hollow Road northbound approach to Etna Road, according to a news release from the department.

The work is weather dependent and will require lane closures of short duration between 9 a.m. and 3 p.m. on Wednesday.

Message boards notifying drivers of the change will remain for approximately one month after the all-way stop is implemented to emphasize the new traffic control.
