Engineers gave Houston-area infrastructure a passing grade Tuesday, but it wasn’t a report card to make a parent – or a taxpayer – beam with pride.

The American Society of Civil Engineers Houston branch assessed the structural and economic viability of roads, transit, solid waste, wastewater and drinking water facilities.

Drinking water systems received a D, and roads and highways got a D+. Bridges, flood control and transit scored a C-, while solid waste received a C and heavy rail systems – freight rail and Amtrak – a C+.
