By Greg Winfree and Zachry Grasley This article was originally published in The Hill, August 20, 2018. This year, we mark 11 years since the Interstate 35 bridge in Minneapolis collapsed into the Mississippi River, killing 13 people and injuring 145 more. For anyone not living there, or otherwise not personally affected by that tragedy, […]

The practice of burying or placing utility lines without adequate documentation has caused large-scale problems across the country. It’s also helped create a new program devoted entirely to the issue. The Utility Engineering Program, formed last year at the Texas A&M Transportation Institute (TTI) to capitalize on the Institute’s two decades of leading-edge research and […]

Roadways don’t build themselves. They require careful planning, construction and regular maintenance, all of which require work zones designed to keep both workers and travelers safe. Sometimes those measures fail. According to the Texas Department of Transportation (TxDOT), in 2017, there were 27,148 work zone crashes in Texas. Of those, 199 were fatalities, and 813 […]

ENCOUNTERING the same construction zones day after day, month after month, it’s only natural for travelers to ask “Why does this have to take so long?” Thanks to a growing reliance on creative thinking, it no longer does. That thinking is at the root of accelerated construction, an effort launched in Texas in 1998 and […]

According to the Texas Department of Transportation’s (TxDOT’s) Accelerated Construction Guidelines, a typical major highway project might take anywhere from 8 to 15 years. TxDOT says decreasing the time it takes to complete the preconstruction phase alone can save $100,000 to $500,000. The construction phase of transportation improvements is often thought of as the determining […]

“This is Texas together on the road to zero,” said Robert Wunderlich, director of the Texas A&M Transportation Institute’s (TTI’s) Center for Transportation Safety as he opened the 2018 Traffic Safety Conference in Sugar Land, Texas. The conference, supported by the Texas Department of Transportation, was held August 8–10. TTI hosts the Traffic Safety Conference […]

The 2018 Texas Child Passenger Safety Conference was held June 24–26 in San Marcos, Texas. About 300 child passenger safety seat technicians (CPSTs) and safety advocates heard firsthand from Michele and Brooke Ice, mother-daughter keynote luncheon speakers, who spoke on the importance of the work they do. Michele credits CPSTs with saving her daughter’s life […]

The old adage, “Cheap, Fast, Good: Pick Any Two,” applies to most things. Defying this commonly held belief, rehabilitating a roadway with cold-in-place recycling (CIR) can actually be faster and cheaper than traditional methods and still yield outstanding results. CIR is a single operation. An existing deteriorated hot-mix asphalt (HMA) layer is recycled and treated, […]
