Description: For almost a decade the Ministry of Transportation of Ontario (MTO) has been accelerating the replacement of its substandard bridges in weekend closures with self-propelled modular transporters (SPMTs). Using SPMTs the MTO has replaced 13 single-span bridges, three multi-span bridges including a curved structure, and two concrete rigid frame bridges. This presentation describes the installation of concrete rigid frame bridges on Highway 401, the first in 2014 with separate precast footings and the second in 2015 with integral footings. Design and construction details will be described, including comparison of footing placements and lessons learned.
