Momentum worked with Barhale on a new, temporary signalised junction, aligned to the south and opposite Varndell Street, as part of the HS2 construction logistics programme. The junction will be designed to temporary standards, given it will be in place for less than six months, and will connect back into the existing Cardington Street alignment, approximately 50m to the east. The existing signalised junction of Cardington Street will be closed temporarily.
Momentum modelled the junction using modelling software Linsig and the results showed that the proposed layout for the Cardington Street junction did not create any network capacity issues. The degree of saturation was well within acceptable levels of service as per Transport for London (TfL) standards.
The proposed right-turn refuge area provided sufficient space for an HGV to turn right without blocking the straight-ahead traffic (Hampstead Road northbound).
The modelling showed that the junction has sufficient capacity to handle the envisaged construction traffic without impacting the highway network.
Momentum led the preparation of the detailed design of highway and transport improvement works surrounding the Euston Station development, securing full approvals with TfL. For the redesign of the new junction, Momentum’s work has been instrumental in providing our client with the necessary design and information to facilitate construction logistics and their utility works. We navigated the challenges associated with the design of a new junction on a busy road in London, working under the Building Information Modelling System (BIM).
Detailed design and civil 3D were at a developed stage before the project was halted by the UK Government in early 2023.
