Monday, April 11th, 2016
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.

Bremerton, WA: The Manette Bridge Documentary

That friend was simply known as the Manette Bridge.

Report Card for D.C.’s Infrastructure

Report Card for D.C.

AMERICAN SOCIETY OF CIVIL ENGINEERS (ASCE)
NATIONAL CAPITAL SECTION
The District of Columbia has 265 bridge structures; 226 of the bridges are owned by the D.C. Department of Transportation (DDOT) and the remaining 39 are owned by the National Park Service (NPS). The average age of a bridge in D.C. is 58 years, and 80% of the bridges will need to be replaced or rehabilitated in the next 10 years. However, the District made significant strides to reduce the number of structurally deficient bridges from 8% to 3% in just three years. Despite this progress, more than 220,000 trips are taken over a structurally deficient bridge every day and a quarter of bridges have at least one major component in fair condition.
