Wisconsin Transportation by the Numbers

Cost to Wisconsin Motorists of Deficient Roads

TRIP
TRIP estimates that Wisconsin roadways that lack some desirable safety features, have inadequate capacity to meet travel demands or have deteriorated pavement conditions cost the state’s residents approximately $6 billion annually in the form of additional vehicle operating costs (including accelerated vehicle depreciation, additional repair costs, and increased fuel consumption and tire wear), the cost of lost time and wasted fuel due to traffic congestion, and the financial cost of traffic crashes.

Streetfilms: The Pulaski Bridge Protected Bike Path Is (Finally) Open!

The Pulaski Bridge had become dangerously congested over the last few years as more and more bikes, pedestrians and runners have crammed on to its narrow shared path. The solution? Remove one lane of the roadway and give the space to a bi-directional cycle track giving the older combo lane to the exclusive use of pedestrians.

Figure 1: United States NPMRDS Roadway Network

AMERICAN TRANSPORTATION RESEARCH INSTITUTE
Trucks transported nearly 10 billion tons of freight representing over two-thirds (68.8 percent) of total domestic tonnage shipped1, and traveled more than 279 billion miles on the nation’s roadway network in 2014.2 Due to the critical role of safe and reliable truck movements in sustainable economic growth, it is essential to continually monitor and evaluate the efficiency of the national roadway system. A key impediment to nimble supply chains is the level of traffic congestion experienced on U.S. roadways, and the subsequent costs that are incurred due to this congestion.

Guest on The Infra Blog: Henry Petroski, Historian & Author of The Road Taken: The History and Future of America’s Infrastructure

Henry Petroski Professor of Civil Engineering in Pratt School of Engineering

Henry Petroski is an Aleksandar C. Vesic Professor of Civil Engineering at Duke University, as well as an author and historian. His most recent book is titled The Road Taken: The History and Future of America’s Infrastructure.

Roads that aren’t paved correctly should not be paid for. They should be redone. If we have something, work done in our house and it’s not done right, we expect the contractor to redo it. We don’t just write another check. I believe unfortunately that too many times the government that represents the people and spends the people’s tax money does do just that.

Outstanding Engineering - Michigan's "96fix"

96fix was the largest single-season construction project in state history. Reconstruction of the seven-mile stretch of the 40-year-old freeway included the rehabilitation of 37 bridges, installation of LED lighting and storm sewers, and safety improvements. The $153 million project was completed early and under budget, and brought I-96 in line with current standards. Innovative technologies included visual modeling to gain public support for closing the freeway during construction and 3-D design model for fine-tuning paving work. The process saved taxpayer dollars, cut freeway closure time, and improved pavement quality and safety.
