Weight restrictions on Route RNT 59B are raising concerns among sand transporters. The measure could lead to reduced supply and increased construction costs. Few vehicles carrying sand on the Ramena route comply with the weight limit. A ministerial decision temporarily limiting the total weight of vehicles on the temporary national road (RNT 59B) between Antsiranana and the rural commune of Ramena has sparked reactions among transporters in Antsiranana. These concerns stem from a transmission letter numbered 309, dated September 2, regarding this limitation. To prevent premature road deterioration and its infrastructure, and pending publication of regulatory text officially setting maximum weight on this route, provisional measures have been implemented. Heavy vehicle owners and drivers specializing in sand transport from Ramena feel particularly affected by this new measure. For them, this limitation represents a significant constraint on their activity and could disrupt Antsiranana's supply. Since sand is essential raw material for construction work, reduced transport volumes could create market tensions. The tonnage limitation fuels discussions around sand transport in Antsiranana. For the Public Works Ministry, the objective is primarily preventing premature road deterioration. Repeated circulation of heavy vehicles carrying loads exceeding road capacity could accelerate pavement and infrastructure deterioration. Weighing and inspection operations may also be conducted at appropriate sites. Transporters, sellers, and construction actors fear reduced supply, increased trips, and ultimately higher prices. Market repercussions are already emerging. If the measure aims to protect the road, its consequences are affecting transporter activity. Any supply disruption could impact the construction sector. For transporters, less sand per trip means more rotations to meet demand. One transporter estimates sand prices in the city could exceed the current 30,000 ariary due to increased rotation costs. According to sector professionals, the number of trucks capable of meeting new limits would be insufficient for current demand. Facing difficulties, multiple meetings with stakeholders continue without consensus emerging. The actual weight of trucks is also debated among transporters, with vehicle specifications and loading capacities contested. Some professionals mention possible conflicts of interest between operators, suspecting some seek advantage from new regulations to strengthen market position. Some transporters even mention market concentration risks, with foreign operators accused of influencing public decisions, though these accusations lack supporting evidence. "I've transported sand from Ramena since 2019. Heavy vehicles carrying containers have circulated in this commune for a long time, not just sand. Why is this decision only now?" asks Eliazara José Randrianary, active in sand transport. The transporter believes current limits could penalize operators who invested in high-capacity vehicles to reduce trips and prevent sand price increases. Another consequence: some transporters say they're forced to seek new supply zones. Among mentioned locations is the rural commune of Ambolobozo, 60 km from Antsiranana.
