[7] The Mong Kok Road Footbridge System began construction in 1998 by Sun Hung Kai Properties, and the section between Mong Kok East Station and Nathan Road was completed in 2003.

[8] After more than two decades of delays,[9] the section of the Footbridge crossing Nathan Road was completed and opened on 30 Sept 2021.

As a result, vehicles from Tai Kok Tsui via Argyle Street, eastbound towards Kowloon City, should make a left turn onto Reclamation Street and then a right onto Mong Kok Road.

For the same reason, all vehicles are not allowed to make a right turn directly from Nathan Road to Argyle Street, and must follow the route described above.

With a large number of buses and minivans passing through this section daily, these intersections have frequently encountered accidents and problems of traffic congestion.
