This project concerns the execution of the works of widening and straightening of the CG1 from PK 8 +889,328 +385,000 to KP 9 (Zone Tolse), Parish of Sant Julia de Loria.

The type section is formed by a slope in rock in the mountain side, curbs of 3.0 m on both sides and four lanes of 3.5 m each.

Along the river did not receive any special action, since the ground and roadway limit unchanged.

For works execution we defined materials, their quality and method of measurement.

It took into account the energy and water needed to carry out the work. Also we use all materials and work necessary for the proper lighting and signaling of the work.
