Stevens Excavation

Excavation works for the station have reached the mezzanine level and are proceeding down to the platform level. The concourse slab has been fully cast, with RC works taking place at the mezzanine slab and mezzanine service slab. Preliminary works have started for entrance E at the Downtown Line structure which will form the basement 1 link to the TEL concourse.
