We deliver Section 278 highway works in Harrow and across North West London for signalisation or crossing works. Section 278 works are required when development impacts existing highways — new access, alterations or works on the public network. On busy routes, phased working and lane closures often govern the install sequence. Highway authority lead times and traffic management approvals often govern programme more than construction duration.

The aim is to avoid assumptions that turn into avoidable delays once work is underway.

It is often used when recurring issues, repair decisions, or planned works need evidence-based scoping before major commitments are made.

This approach helps reduce uncertainty, limit disruption, and achieve a more reliable long-term result.
