In 1989, Eastern Harbour Crossing was completed. Kwun Tong Bypass was completed in 1991. To construct an interchange for both roads, the intersection between Lei Yue Mun Road and Kai Tin Road was rebuilt into a flyover-roundabout. This made Lam Tin a bridge between the Eastern Harbour Crossing and the Kwun Tong Bypass of Route 2, with Lei Yue Mun Interchange as the exit point.
