Construction of a New Nemaska Lithium Plant in Bécancour

A study tailored to the project’s unique characteristics

To conduct this study and propose appropriate mitigation measures, Intervia’s mobility planning team needed to account studies for the project’s unique nature, spanning road, rail, and maritime traffic, and two study scales: local and regional.

The process began with a characterization of current conditions across the three transportation networks, describing traffic volumes and circulation patterns. From there, the team projected traffic flows for both the construction and operation phases to assess potential impacts across all transportation modes. These projections allowed Intervia to recommend mitigation and optimization strategies addressing issues related to traffic flow, safety, and project implementation.

Challenges and key considerations: our experts adapt to every context

This highly specialized project brought its share of challenges successfully met by our team. The industrialized nature of the area meant that mobility patterns differed significantly from those typically seen in commercial or residential zones.

During the construction phase, specific logistics measures had to be developed to accommodate the travel of a large workforce to and from the site. At the same time, the increase in noise levels caused by train movements near the Abenaki community of Wôlinak was a major concern for both the municipality and the client. Intervia therefore proposed innovative mitigation solutions, including noise barriers and automatic safety gates at railway crossings, to address both noise and safety concerns.
