[1] As part of the Tsuen Wan District Improvement Plan, Texaco Road underwent renovation and widening works starting in September 1959,[2] with the project lasting six months.

[4] After the completion of the Tsing Tsuen Bridge and Shing Mun Tunnel (then called “Route 5”), the traffic volume on Texaco Road increased significantly, surpassing its capacity.

Construction began in April 1989, and the Texaco Road Overpass opened to traffic on December 28, 1991, with the inauguration ceremony held the next day by Acting Director of Territory Development [zh] Chow Che-King.

[10] Phase 2 primarily involved constructing the Tsuen Tsing Interchange and a section of reserved overpass,[8] which started in April 1992[10] and was completed in 1995.

Additionally, the reclamation plan for Tsuen Wan District was canceled due to the Protection of the Harbour Ordinance, resulting in lower-than-expected traffic growth.

[13] Texaco Road features a 700-meter overpass that begins at the Tsing Tsuen Bridge approach and ends near Tak Tai Path.

[19] In July 2002, the Environment, Transport and Works Bureau submitted a proposal to the Environmental Affairs Panel of the Legislative Council suggesting a ban on all vehicles from using the Texaco Road Interchange between midnight and 6 a.m. to reduce traffic noise impacting nearby residences.

[21][22] Subsequently, the Environmental Affairs Panel of the Legislative Council passed a motion,[23] and from July 4, 2005, a traffic management plan was implemented on the Texaco Road Interchange.

[11] In 1999, the Transport Bureau [zh] reviewed traffic patterns in Tsuen Wan District and decided to shelve Phase 3, believing that Route 9 would divert heavy vehicles away from Texaco Road Interchange.

Due to a subsequent halt on Tsuen Wan's reclamation plans under the Protection of the Harbour Ordinance, traffic growth in the area was slower than anticipated.

However, the Transport Department indicated that Texaco Road Interchange met current local traffic needs, so no plans for Phase 3 were initiated.

He again proposed connecting the stub bridge to Texaco Road's surface lanes, to which the government provided an unsatisfactory response.

Members Jonathan Tsui Hiu-kit [zh] and Law King-shing [zh] put forward a motion to "urge the Transport Department and Highways Department to promptly complete the Texaco Road stub bridge to alleviate traffic congestion in Tsing Yi and Tsuen Wan," which was unanimously passed by the Committee.

[29] The Highways Department later included the connection of the stub bridge as part of the Tsuen Wan Road widening study, with related surveys commencing in May 2019.
