IHC has been building highways for state Departments of Transportation (DOTs) since 1947. We have won numerous awards for quality, partnering and project management. Our highway projects have ranged in size from less than $1 million to over $30 million. Over the last ten years our primary DOT customers, served from our division offices, have included Michigan, Colorado, Wyoming, New Mexico, Oklahoma, Kansas, Texas, and Arkansas. Internationally, in conjunction with Cemex, we have constructed roads and concession toll roads in Mexico, introducing modern slipform methods for PCCP in a technology transfer program initiated by Cemex with Mexican transportation officials.
