All of VT 22A north of Fair Haven was originally designated as Route 30A, a highway in the New England road marking system, in 1922.

Continuing northwest out of downtown Fair Haven, VT 22A retains the Washington Street moniker through Fair Haven, approaching the New York state line once again, however it bends north less than 1-mile (1.6 km) east of the Poultney River.

North of the county line, VT 22A enters the town of Orwell, crossing through more rural areas in Addison County, crossing a junction with VT 73 (Main Street) as it bypasses downtown Orwell.

VT 22A continues winding through rural Addison County, crossing into the town of Bridport just south of North Cream Hill Road.

The route passes through more farms as it winds northward, soon reaching the commercial center of Bridport.

The scenery around VT 22A does not change much in Addison, running northeast and soon northwest as it passes multiple residences in the area.

North of VT 17, the route bends northeast, passing multiple residences on both directions.

Just after Canal Street, the route crosses the Otter Creek and enters the center of Vergennes.

VT 22A turns northeast further, crossing past residences as North Main Street, making a large curve around railroad tracks as it leaves the village of Vergennes and reaches the town of Ferrisburgh right after the tracks.
