Chile's public works (MOP) minister Sergio Bitar opened the US$46mn Llo-Lleo bridge along the access road to central region V's San Antonio port, the country's busiest, MOP reported in a release.
Repairs needed to be carried out on the bridge even before it was opened after MOP found a series of defects in the construction work last November.
The structure, built by Spanish concessionaire OHL, will allow trucks to bypass the town of Llo-Lleo.
The overall project cost US$210mn and included the construction of a four-lane highway connecting the Aguas Buenas feeder road to the port, including a tunnel known as Trinchera. Another road was built to connect the Independencia area with the highway known as Camino de la Fruta.
