Overview
Multiple long-term infrastructure works and localised restrictions are currently impacting key transport corridors across London, contributing to sustained congestion and route inefficiencies.
Strategic Road Corridors
A12 – Eastern Avenue / Gallows Corner (Havering)
Ongoing refurbishment works continue to affect traffic flow across one of East London’s primary arterial routes.
Multi-directional restrictions and previous full closures impacting junction capacity
Displaced traffic affecting surrounding routes including A13 and M11
Average delays: 3–10 minutes depending on time and diversion usage
A13 / A1205 – East India Dock Road / Burdett Road (Tower Hamlets)
Utility works are creating localized disruption at a key East London junction.
Lane restrictions in both directions
Thames Water works affecting junction throughput
Minor but persistent delay patterns
A23 – Streatham Hill Corridor (Lambeth)
Long-term TfL works continue to reduce capacity across South London.
Ongoing lane restrictions across main carriageway
Planned overnight closures (June window)
Widespread spillover into surrounding residential roads
Inner Ring Pressure
A400 – Hampstead Road (Camden)
HS2-related works continue to impact Inner London traffic flow.
Temporary signals and restricted movement
Local road closures (Varndell Street)
Long-term disruption extending through 2027
Network Impact Summary
Across these corridors, the network is experiencing:
Reduced capacity on key arterial routes
Displacement traffic onto secondary roads
Increased journey time variability
Compounding delays during peak periods
Operational Signal
This pattern reflects multi-layered infrastructure pressure, where long-term works, utility interventions, and diversion flows interact across multiple zones rather than isolated locations.
