Island Eastern Corridor
The Central–Wan Chai Bypass () is a four-kilometre trunk road running between Sheung Wan and Fortress Hill on Hong Kong Island. The original design consists of a 2.3 km dual three-lane tunnel running under new reclamation areas provided by the Central and Wan Chai Reclamation project, and also connections to Connaught Road West flyover and Island Eastern Corridor. It substitutes Connaught Road Central, Harcourt Road, Gloucester Road and Victoria Park Road to be part of Route 4.
