New Diversion Plan for Port Louis Street Closed by Landslide
A revised traffic diversion takes effect Monday 16 June on Rue Monseigneur-Leen in Port Louis, where a landslide forced road closures and caused major congestion.
Drivers navigating central Port Louis are facing a new set of traffic rules from Monday 16 November 2026, as authorities roll out a revised diversion plan for Rue Monseigneur-Leen, a road closed after a landslide damaged a section of the carriageway.
The street, which runs through a busy part of the Mauritian capital, was shut following the ground movement that made it unsafe for vehicles. The closure has since created significant congestion in the surrounding area, affecting commuters, businesses and public transport routes that depend on that corridor.
Repair works have been awarded to Transinvest Construction Ltd, a local civil engineering firm. The contract is valued at an estimated five million rupees. While works are ongoing, traffic managers have been adjusting diversion routes to try to ease the pressure on nearby streets.
The new plan coming into force on Monday represents a revision of the original detour arrangements, suggesting that the earlier routes were not adequately reducing bottlenecks. Authorities have not yet indicated a completion date for the repairs, meaning the diversions could remain in place for some weeks.
Rue Monseigneur-Leen is named after a Catholic bishop and connects parts of central Port Louis, making it a commonly used route for both private vehicles and commercial traffic. Its closure has had a knock-on effect on parallel streets, which have absorbed the additional volume of vehicles.
Landslides are not uncommon in parts of Mauritius, particularly during periods of heavy rainfall. Steep gradients and saturated soil in and around Port Louis can make road infrastructure vulnerable, and the capital's narrow historic street grid offers limited flexibility when a key route is taken out of service.
What this means for drivers and residents: anyone passing through the affected area of central Port Louis from Monday should expect altered traffic flows and allow extra travel time. The revised diversion is designed to distribute congestion more evenly, but significant disruption is likely to continue until the road is repaired and reopened. Motorists are advised to check local traffic updates and consider alternative routes where possible, particularly during morning and evening peak hours.
