Engineering experts have declared the retaining wall at Quai Paquet in Lévis at the end of its useful life [1].

The degradation of the structure poses a potential risk of collapse, forcing the city to restrict public access to certain areas to ensure safety.

According to a report released July 24 [3], the steel retaining wall dates back more than 75 years [4]. Experts identified significant erosion, deformation, and structural fatigue as the primary causes for the wall's failure [4]. These conditions have compromised the integrity of the quay, necessitating immediate precautionary measures.

As a result, a 15-metre section of the quay has been closed to the public since January [2]. This specific zone was shut down following the discovery of important deformations in the structure [4].

Despite the partial closure, the City of Lévis said that approximately 70% of the site remains accessible [1]. The city intends to keep the majority of the quay open to allow summer programming to continue for residents and visitors [1].

The city and its contracted engineering experts are now assessing the long-term requirements for the site. The current closure of the 15-metre segment serves as a buffer while the city determines the next steps for repair or replacement of the aging steel structure [2].

“The retaining wall of the Paquet quay has been declared at the end of its useful life.”

The situation at Quai Paquet highlights the challenge of maintaining aging municipal infrastructure in waterfront environments. The 75-year lifespan of the steel wall suggests that the city is facing a systemic replacement cycle for its maritime structures, where natural erosion and material fatigue eventually outpace routine maintenance.
