The multi-level Turcot Interchange (Turcot) is an element of paramount importance in Montreal’s road network, with an average of 300,000 vehicles daily. It interconnects three highways, one of which leads to downtown Montreal.

Commissioned in April 1967, Turcot is a cast-in-place concrete box-girder structure. It covers an area of 100,465 square yards (84,000 square meters) and its ramps total 4 miles (7.7 km) in length. The repaired ramps were generally 50 to 90 ft (15 to 28 m) aboveground. Adding to the difficulties, work areas overhung other ramps and streets where uninterrupted traffic flows 24/7. Also, five major railway tracks where freight and passenger trains circulate 24/7 are located under Turcot.

After 45 years of extensive service, severe damage from the use of deicing salt, and delayed maintenance and rehabilitation work, Turcot is scheduled for demolition and reconstruction from 2015 to 2020. However, extensive and urgent remedial work was necessary to ensure Turcot’s integrity and the safety of its users until it is no longer needed.

Extensive demolition and repair work was performed on the pillars, exterior walls, and underside of the structure for six ramps, including resurfacing, from September 2011 through October 2012. The total length of repaired running surface was 6000 ft (1825 m), for an area of 22,045 square yards (18,433 square meters), requiring 3015 cubic yards (2304 cubic meters) of latex concrete. Custom-made equipment was designed and built for the leveling, finishing, grooving, and curing of the latex concrete.

The project represented a great logistic challenge both during the preparation of the site (including planning of road traffic detours, coordination with the railway company, and supply of water and electricity throughout the site) and during the execution of the work (such as major concerns for the safety of workers and motorists, treatment of wastewater, and removal of debris).
