This encompasses a new at-grade bus/rail interchange and enhanced station. Buses will still use the existing local road (Bridge Street) to cross the railway line to/from Manukau, along with local traffic. The second phase provides a rapid transit overbridge across the railway line to provide a more direct and bespoke rapid transit connection. The new rapid transit link will integrate with the new interchange station on the overbridge. The first stage is estimated to cost $59 million to construct. The line will also go through Manukau railway station before ending in Botany.
