Inflation is taking a toll on infrastructure projects across the U-S. Rising prices for materials such as asphalt, steel and iron pipes are driving up the costs to build roads, bridges, and water mains. The costs of some infrastructure materials have risen even faster than general consumer prices. State and local officials say inflation is diminishing the value of a $1 trillion federal infrastructure law signed by President Biden just seven months ago. Some officials say inflation has forced them to delay or scale back the scope of projects. Federal infrastructure funds have een allotted for flood prevention and the replacement of lead pipes in Detroit.
