Starting July 12, the quickest daytime route between Farmington center and Unionville will be via Avon. A water line reconstruction project will close Route 4, the town’s busiest thoroughfare and the main connector for towns to the west heading to the highway. Regular traffic patterns should return in September. Access to town hall, the library, homes, the Wood-n-Tap and other small businesses will be maintained, but it won’t be possible for through traffic to get from Brickyard Road to Route 167 on Route 4. Instead, eastbound drivers will be detoured up Route 167 — West Avon Road — at the Pine Grove Schoolhouse in southern Avon, and then down Brickyard to reconnect with Route 4. Westbound drivers will follow the same detour but in the opposite order. “Connecticut Water Co. estimates that the detour should be complete by the end of August and the project should be complete by end of September,” the town said in an announcement. Farmington police will station patrol officers and community service officers at both detour points on Route 4. The detour will be in effect Mondays through Fridays from 7 a.m. to 5 p.m.
