Highway 401 Expansion

Project Overview

Location: Tilbury to London, ON
Client: Stantec
Services: Geomatics, Geomatics Engineering, Geospatial & LiDAR
Sector: Transportation

Project Description

The Ontario Ministry of Transportation initiated a multi-year program to widen approximately 116 km of Highway 401 between Tilbury and London and advance interchange, structure, and safety improvements along the corridor.

Stantec retained TULLOCH as Engineering Survey Lead to establish the survey framework and existing-condition information required for preliminary and detailed design. The assignment combined conventional field surveying with mobile LiDAR and photogrammetric data to efficiently document a long, active highway corridor.
