The United States has the largest road, highway, and bridge network in the world. It includes approximately 4 million miles of state and local roads, 136,000 miles of federal highways & 604,000 bridges. These networks are vital to the nation’s economy due to the ability to freely move people, goods, and services. Most road and bridge networks have exceeded their useful lives and need to be rehabbed or replaced. There is an overwhelming need to find and repair deficient roads and bridges to ensure America keeps moving. Having a non-destructive means of inspecting road and bridge assets will give owners a cost-effective means of prioritizing repairs. EnTech® makes sure your road and bridge networks are sustainable.
