Mexican infrastructure developer IDEAL has emerged as the likely winner of the federal government's Pacífico Sur highway concession package, after presenting the sole bid for the project.

The company offered 8.13bn pesos (US$693mn) to carry out the project, with an initial payment of 4.05bn pesos, paper El Semanario reported.

Grupo Hermes, ICA and OHL had all expressed interest in the concession, with the latter two firms submitting letters of apology, the paper said.

The concession is due to be awarded on May 12.

The project involves building the 111km Sur de Guadalajara bypass and 30km Tepic bypass, as well as operating the existing 169km Guadalajara-Tepic highway, which connects Jalisco and Nayarit states.

IDEAL was awarded the Pacífico Norte highway concession package in October 2009. The concession includes 242km of highways, of which several link to routes included in the Pacífico Sur package.

The Pacífico Norte and Sur concessions total 600km of highways and are part of the Farac federal highway re-concessions program.
