Traffic & Public Impact
Due to the scale and coordination of works:
Two-way signal control will be in place throughout key phases
Delays and congestion are expected along Warham Road
Temporary disruption will affect local traffic and journey times
The coordinated delivery between utilities is designed to minimise repeated roadworks and reduce overall disruption.

Conclusion
This scheme represents a significant infrastructure investment in Croydon, improving the reliability and capacity of both gas and electricity networks.
