After nearly 30 years, Lima Metro Line 1 is finally complete. Work on Line 1 began in 1986 but was abandoned during the economic crisis of the 1990s. The project remained on hold until 2009, when construction finally resumed. Phase two was awarded in 2011, allowing for the July 2014 completion of Lima's first metro line to connect the city's peripheral districts.
One judge noted that Line 1 was a "highly complex project in a very dense urban area with lots of sensitivities." The project crosses through heavily populated sectors, highways, the historic district of Lima and the Rimac River. The project was completed in 36 months, three months ahead of the contractual deadline, for a total of $885.2 million. Several strategies, designs and technologies enabled the shortened completion time, including, during preconstruction, the relocation of water, electrical, gas and other utilities as well as 12.4 kilometers of overhead viaduct.
