Mexico's Nuevo León state government will invest 1.64bn pesos (US$138mn) in a bus rapid transit (BRT) system for state capital Monterrey.
The system, known as Ecovía, will run over 30km from the city's Lincoln avenue to Ruiz Cortines.
The BRT line will involve 112 buses running through 40 stations, serving 160,000 passengers each day, according to a state government release.
The project will also involve reorganizing 47 existing public transport routes in the city, said the state government's head of sustainable development, Fernando Gutiérrez.
The federal government is providing 610mn pesos for the transport project through national development bank Banobras.
The system is due to begin operating in 2012.
