The fact that Shun Long Rd serves as a motorway connector between the North Lantau Hwy and Tuen Mun -CLK Tunnel underscores my intention of differentiating Chek Lap Kok Rd as a distinct road, rather than an extension of an extended slip road. 
Considering your reference to Hung Tin Rd, why do we not have Tsing Tin Road as a Trunk Link from the Tsun Wen Road interchange?
