Evolution of Bridge Practices in Ontario, Canada

Abstract

The Ontario Ministry of Transportation (MTO) manages provincial structures in Ontario including 2850 bridges. Following an extended period of fiscal restraint, the last decade has marked a dramatic increase in bridge construction work, with rehabilitation of a third of the provincial bridge inventory.
Bridge design and corrosion protection have evolved over the last 60 years. The practice of bridge rehabilitation is well-established in Ontario. Through the 1990s, standards were introduced for integral abutments, semi-integral abutments, and flexible links slabs between simply-supported spans to improve a bridge’s durability in initial construction or rehabilitation. Accelerating bridge construction by reducing time on site is a current focus. The MTO has tried many forms of prefabrication.
