This study reports findings of the study to seek to minimise the increase in height of the road levels of A400 Hampstead Road due to the HS2 works at either end of Hampstead Road Bridge (HRB).
The aim of this study was to identify the options that would achieve lower road levels at either end of the re-provided HRB in order to reduce the impact on local residents and neighbouring buildings as well as on non-motorised users (NMU) of A400 Hampstead Road.
The report brings together the technical material discussed and developed through multiple workshops. It is intended to provide technical information on alternative bridge options. It also provides details of the preferred HS2 option – Option 8 – which would see the bridge being lowered by up to one meter compared to the current AP3 scheme.
Representatives of High Speed Two Limited (HS2 Ltd.), Network Rail (NR), Department for Transport (DfT), Transport for London (TfL) and London Borough of Camden (LBC) have attended collaborative workshops in order to ensure stakeholders have an input into the options comparison and decision making process.
This partially discharges assurances made to TfL and LBC during the House of Commons Select Committee Stage of the HS2 hybrid Bill (hB) in December 2015.
The report has been considered by the Promoter (DfT) which has accepted HS2’s recommendation.
