Eagle's Nest Tunnel is a road tunnel in Hong Kong. Officially opened on 21 March 2008, it connects Cheung Sha Wan and Sha Tin Valley through Eagle's Nest hill in Hong Kong in anticipation of future traffic demands generated by development in the northeast New Territories. It links south to Stonecutters Bridge and Nam Wan Tunnel, and north to Sha Tin Heights Tunnel to form a series of highways.
