The first road was Lei Yue Mun Road, which succeeded Kwun Tong Road and ran between Kwun Tong and Lei Yue Mun. Cha Kwo Ling Road was later built to tap traffic to Cha Kwo Ling. However, the roads had insufficient capacity to effectively serve the district. Both Lei Yue Mun Road and Kwun Tong Road were widened and became segments of today's Route 7.
