Lees and Riverside Replacement

As part of Ottawa's Light Rail Transit project, the existing underpass bridges at Lees Avenue and Riverside Drive required rapid removal and replacement with new structures to allow for the widening of Highway 417.

OTTAWA, ON

As part of Ottawa's Light Rail Transit project, the existing underpass bridges at Lees Avenue and Riverside Drive required rapid removal and replacement with new structures to allow for the widening of Highway 417.

Entuitive served as the Bridge Engineering and Construction Engineering Consultant on this project to remove and install bridge superstructures via Self Propelled Modular Transporter (SPMTs) rapid replacement technology.

The removal and replacement of the Riverside Drive Underpass on Highway 417 required the rapid lift of a new two-span continuous concrete bridge superstructure between staging area and the permanent location.

Each instance of bridge rapid removal and replacement was completed within the very short time frame of two overnight highway closures.

The installation of the new Lees Avenue Underpass on Highway 417 was completed by the rapid lift of a prefabricated two-span continuous steel bridge superstructure from the staging area to the permanent location. This stage of construction had the distinction of involving the heaviest super-elevated bridge units (2100 tonnes) in North America at the time, using Rapid Lift Technology.
