Each tube of the tunnel will have 600 LED lamps, costing US$860 each and 230 high-pressure sodium lamps, which will cost US$530 each. The lighting equipment is being supplied by 4196 Comatelec, with 4199 Cegelec providing electrical assistance and 4200 Clemessy will be in charge of supplying a management centre.
