Scammon Bay is accessible by air and water. A state-owned gravel airstrip and city-owned seaplane base on the Kun River serve air traffic. Barges bring in bulk supplies each summer. Winter trails exist to Hooper Bay (32 mi) and Chevak (25 mi). Snow machines and skiffs are the primary means of local transportation. In November 2013, the city experienced a flooding event that damaged sections of the dock roads and washed out other areas of the road. As of May 2014, a project to improve existing roads was underway.
