Lima’s Santa Rosa Tunnel on track, despite collapse

0

Part of the Santa Rosa Tunnel collapsed over the weekend, El Comercio reported.

According to the daily, some 800 cubic meters of rock detached from the Santa Rosa Hill on Sunday, partially blocking the entrance of the unfinished tunnel.

The incident is the second time a collapse hits the project, after work was interrupted in February 2011, when part of the tunnel collapsed during drilling.

However, Alvaro Espinoza, head of Lima’s Toll Administration (Emape), said the collapse would not further delay the project, and said the tunnel, which will link the districts of San Juan de Lurigancho and Rimac, is scheduled to be completed in 2014.

After the 2011 collapse, a review of the project was carried out by a Spanish consultancy firm, which recommended strengthening the tunnel’s embankments and ceiling.

However, according to Espinoza, the improvements to the tunnel’s infrastructure would only be implemented once work resumes in June.

"Fault lines will always be present in the hills. The key is to detect them in time,” Espinoza said according to Peru21.

"These improvements are included in 70 million soles budget, for this new project,” he added.
