The Half Dome View contractor on HWY 120 (Allison Sierra) will be controlling/flagging traffic into one lane on the 12th, 13th and 14th of Aug. The flagging operation will take place about 1/4 mile above the Big Oak Flat Tunnel on HWY 120 [actually that's not highway 120 there] at the Half Dome View project site. Traffic will be flagged into the uphill lane with the downhill lane closed off for construction (asphalt paving of parking lot).
