LEA’s Contract Administration division has been extra hard at work this year in Southwestern Ontario with a number of large and complex 400-series highway projects for the Ontario Ministry of Transportation (MTO). Among these endeavours are the extensive rehabilitation efforts on Highway 402 in London and Highway 403 through Brantford and Woodstock. Read on to delve into the details of these projects.
Project: MTO 2021-3006 Design-Build
Contractor: AECON/ GIP
Contract Administrator: LEA Consulting Ltd.
Rehabilitation of Highway 403 from Highway 401 easterly to 1.4 km east of West Quarter Townline Road.
Within these limits Highway 403 is a four-lane rural freeway with a grassed median. Interchanges are found at Highway 401 (Freeway-to-Freeway) and Oxford County Road 55. Underpass structures are found at Township Road and Oxford County Road 14.
This project involves mainline and interchange ramp pavement rehabilitation and the structural rehabilitation of the Oxford Road 14 underpass, the Township Road underpass, and the Kenny Creek Bridges (both eastbound and westbound).
The design was completed in 2022 and construction commenced on March 20, 2023. As of September 30, 2023, the Contractor Progress was:
• Design: 100%
• Construction: 43.50%
• Total: 48.7%

Rehabilitation of Highway 402 from 1.0 km west of Colonel Road to 0.9 km west of Digman Drive in the County of Middlesex, including mainline pavement rehabilitation, resurfacing the interchange ramps at Wonderland Road and the N-E and E-N/S, precast culvert installation and spray lining operations at two twin CSP locations.
This project implemented a method of repairing existing CSP culverts running under Highway 402 at two locations using a monolithic spray-on lining product. The Subcontractor used an application of a high-build, rigid, and solvent-free polyurethane coating to eliminate infiltration, provide corrosion protection, repair voids, and complete structural integrity. The process allowed rehabilitation work to be completed without excavation of the existing highway and staging of traffic flow throughout the project limits. During the second Season, a robot application method (SPOD – Rotary Impingement Spray Robot) was approved by MTO for the spraying operations.
