At Chelsea Embankment Foreshore, we are working across two sites, known as the ‘north’ and ‘south’ sites. Our south site is located on the foreshore where we have constructed a cofferdam, a dry working area built out into the river. Within this cofferdam we have excavated a 45m-deep shaft. From the base of this shaft, we have constructed a connection tunnel that links the site to the main super sewer below the River Thames. On our north site – across the road from our south site - we have excavated a 23m-deep overflow weir chamber. This chamber will receive the sewage that overflows from the Low Level 1 sewer and direct it towards our shaft on our south site via a connection culvert tunnel.

Closure of Bull Ring Gate and access to Royal Hospital Grounds (August 2022 to March 2023)

To facilitate our work there is a temporary closure of the Bull Ring Gate from August 2022 until March 2023. The closure includes the pedestrian access gate to the Royal Hospital Grounds. See our works notice here. 

Bus number 360 continues to be diverted and now stops by the Lister Hospital on Chelsea Bridge Road. The parking bays within the Bull Ring also remain suspended for the duration of these works.
