Rovira Tunnel Works Hit by Unexpected Rock City officials explained the overrun with a list of seven factors. The primary issue was encountering rock far harder than anticipated during drilling for new evacuation galleries. This discovery required additional measures and caused significant delays.
But it wasn’t just geological surprises. The project scope also changed. However, mobility manager Ricard Font stated that initial plans for a three-month full closure were altered. Instead, one of the two tunnel tubes has been kept open for outbound traffic towards Ronda de Dalt, minimising disruption.
Political Reactions and Broader Transport Context The budget revision passed with support from most opposition groups, except Vox. However, the approval didn’t come without criticism. However, junts argued the increase showed poor initial planning.
The tunnel’s renovation is a key piece of local infrastructure.Its cost overrun follows a pattern of complex urban projects facing budgetary pressures. The works, carried out by a temporary union of companies Acciona and Copcisa, beat ten other bidders for the original contract.
According to the original report in El Periódico, traffic management is currently focused on the ascending tunnel tube, which is closed, while the tube towards Guinardó remains open during daytime hours.
