Lima's Metro Line 2 project comprises 27 km of all-underground Line 2, plus an 8 km underground spur to the airport which will make up the first section of Line 4. Thirty-five new stations are being constructed, seven of them mined and the rest constructed by cut and cover. The MDL2 consortium is to design, finance and build the new line and to operate and maintain it for the following 30 years.
