The HK$782 million contract—Highways Department's largest engineering contract since its formation—for the construction of Kwun Tong Bypass Phase 2 was awarded to the Dragages–Bachy Soletanche joint venture.

The novel construction method of using precast concrete slabs resulted in the early completion of works by one month.
