18 Miles
170 Sq. Mile Watershed



The expansion of this 18-mile, heavily-traveled corridor from four to six lanes (one lane in each direction) now makes commuting a lot easier for motorists on I-10 from Las Cruces to the Texas border near El Paso. The overall project included two new bridges at the I-10/I-25 Interchange, two replacement bridges, and the expansion and rehabilitation of a fifth bridge. Additionally, the project included a major drainage analysis encompassing a total watershed of 170 square miles and the design of more than 140 culvert extensions within the median. Molzen Corbin managed the design project, which involved more than 60 technical design professionals within a team of six companies, and brought the project to completion on time under extremely tight deadline pressures.
