HS2 Saltley Viaduct replacement: traffic staging and risks for project teams
Reviewed by Tom Sullivan
First reported on New Civil Engineer
30 Second Briefing
Closures on the A47 Heartlands Parkway in Birmingham will begin this weekend as HS2 starts preparatory works for an 18‑month programme to replace the Saltley Viaduct, a key multi-span structure carrying traffic over rail infrastructure. The works will involve staged traffic management and partial closures to maintain access while HS2 constructs the new viaduct offline and prepares tie-ins to the existing highway. Contractors and local authorities will need to manage significant disruption to a strategic route while coordinating with rail possessions and utilities diversions.
Technical Brief
- Initial A47 works focus on enabling activities for the 18‑month Saltley Viaduct replacement programme.
Our Take
HS2-related pieces in our database increasingly feature complex urban interfaces like the Chiltern tunnel portals and Euston Tunnel drives, signalling that the Saltley Viaduct works in Birmingham will be managed alongside several other technically demanding, traffic‑sensitive construction fronts.
An 18‑month operation window for the Saltley Viaduct replacement suggests prolonged traffic management on the A47, which in UK city contexts typically forces contractors to phase works tightly around utility diversions and rail possessions to limit economic disruption.
With 726 Infrastructure stories and nearly 2,000 tag‑matched project and contract items in our coverage, HS2 appears consistently as one of the most active UK clients, meaning lessons from earlier packages (like the track systems and Euston PPP market engagement) are likely to inform risk allocation and stakeholder handling on the Saltley Viaduct scheme.
