New Mexico Best of 2007/US 550/Arroyo Penasco Retaining Wall

摘要

The construction team on this project found a unique solution to erosion control: roll out used tires to stop an arroyo from eroding a right of way. The 490,000 dollars project began June 2006 and was completed September 2006. Along US 550 northwest of San Ysidro, the meandering Arroyo Penasco, with vertical banks, was cutting into the highway right-of-way, so much so that in just one year it had devoured 15 ft laterally, leaving the right-of-way fence suspended 30 ft in the air.
