The High Capacity Line (in Spanish Línea de Alta Capacidad, commonly known as LAC) is a BRT (bus rapid transit) system for the city center of Granada (Spain) integrated into its urban bus network.

Its main objective is to provide a high frequency service to the center district, complementing the Granada Metro and the rest of urban bus lines.

Its management and ownership, as the rest of urban bus lines, corresponds to the area of mobility of the Mayor of Granada.

In these four kilometres of tour are located the major concentration of shops and hostelry, monuments and centres of cultural interest or administrative.

They have four doors that allow the entrance and exit of passengers, one of them with a ramp to allow access for people with reduced mobility.
