[3] The road was built as initiative from the Crosslinks Further Study, which highlighted the need for another vehicular cross-border link between Hong Kong and Shenzhen.

At the date of the study (2001), there were three existing vehicular border crossings, located at Lok Ma Chau, Man Kam To and Sha Tau Kok.

[4] At that time, these links were nearing saturation and were expected to reach their maximum handling capacity by 2006.

Gammon Construction (at that time incorporated as "Gammon Skanska Limited", partially named after Skanska, a co-owner of the company) was the principal contractor for the northern section, and built around 4 km (2.5 mi) of the carriageway.

Ling Lo Tsz, a Chinese temple, is accessible from a branch road off the carriageway.
