Construction considerations

Traffic management

Construction activities can create temporary congestion. The project uses traffic-management plans, alternative routing, signage and public awareness measures.

Dust and environmental management

The report identifies dust and emissions as an environmental consideration. Mitigation measures include water spraying, equipment management and environmental monitoring.

Utilities and right-of-way coordination

Relocation of electricity and water infrastructure remains part of the construction coordination process.
