Infrastructure Week is a week of education and advocacy highlighting the state of infrastructure in the United States and the projects, technologies, and policies necessary to make the US competitive, prosperous, and safe. This year, IWeek runs May 14 through 21.

The American Society of Civil Engineers released an Infrastructure Report Card grading United States roads with a D, saying US roads are too crowded, in poor condition, and chronically underfunded. ASCE reports an $836 billion backlog of highway capital needs, including repairs, expansions, and enhancements. As a part of Infrastructure Week, we’re encouraging America that it’s time to build and invest in our nation’s roads.

At Transtec, we find ways to make infrastructure cost less. We reduce taxpayer burden by designing pavements that last longer, are more sustainable, safer, and cost less to construct and to maintain. Since 2014, we’ve saved more than $370 million on highway projects, all while improving the quality of life for everyone who uses transportation. Here’s a look at five of our largest infrastructure projects:

1. Purple Line | Maryland

We developed an asphalt pavement design for the 16-mile, $2.4B light rail transit project. The public-private partnership (P3) project will provide rapid and reliable east-west travel to the Washington Metro area, and will provide direct connections to four Washington Metrorail lines, three MARC commuter rail lines, Amtrak Northeast Corridor, and regional and local bus services. Our innovative, cost-effective design will ensure a long-lasting roadway to support the new light rail tracks.

2. I-4 Ultimate | Orlando, Florida

The $2.3B I-4 Ultimate project included reconstruction of 21 miles of highway and the addition of tolled express lanes to improve traffic flow throughout the corridor. The new roadway is expected to increase safety, ride quality, convenience, and highway capacity. We served as the pavement designer for this award-winning P3 project, and our innovative asphalt pavement design led to reduced risk, increased performance, and significant cost savings.

3. Central 70 | Denver, Colorado

The Central 70 project is the largest infrastructure development project in the Colorado Department of Transportation’s history. It will reconstruct a 10-mile stretch of I-70, adding a new express lane in each direction, removing the 54-year-old viaduct, lowering the interstate, and placing a 4-acre park over a portion of the lowered interstate. Transtec provided an optimized pavement design to the $1.17B project.

4. SH 99 Grand Parkway Segments F1, F2, G | Houston, Texas

SH 99 Grand Parkway is a 184-mile highway circling the Houston metro area. It aims to improve mobility and increase travel capacity around the city. Segments F1, F2, and G are a 38-mile stretch of the highway built with one million cubic yards of concrete. We provided pavement designs and construction support to this $1.1B design-build project. Additionally, our concrete temperature and maturity monitoring system, COMMAND Center, was implemented on this award-winning project. COMMAND Center was used to monitor the internal concrete temperature of mass concrete elements during construction.

5. DFW Connector | Dallas, Texas

The DFW Connector project was an 8-mile reconstruction and improvement of four highways, two interchanges, and five bridges. The $1.02B project aimed to reduce congestion, accidents, and air pollution. We provided optimized pavement designs and materials and mix designs for mainlanes, frontage roads, and temporary roads. Our designs included asphalt, concrete, and reinforced concrete pavements, and significantly reduced the construction cost by $500,000.
