The project to reconstruct the intersection of Wilson, Clarendon and Washington Boulevards — known as Clarendon Circle — is scheduled to start on Monday, Sept. 24. The first phase of the project will involve concrete work along eastbound Washington Boulevard, west of Wilson Boulevard and Fairfax Drive. First, the contractor will install erosion and sediment controls and tree protection. Once these items are inspected and approved, construction will begin. Project work hours will be 9 a.m. to 4 p.m., Monday through Friday, during activities that require a temporary lane closure. Other activities may occur outside these hours, but this work will adhere to the requirements of Arlington’s Noise Ordinance. No weekend work is expected. The expected duration for the first phase of construction is about 10 weeks – weather permitting. Detour signage will direct vehicles and pedestrians around construction zones.
