Crystal River Works to Save Manatees and the Local Economy
Crystal River, Fla., is the self-proclaimed “home of the manatee.” An estimated 300,000 tourists visit Crystal River each year, many of them to see and experience the graceful manatees, the giant herbivores often referred to as “sea cows.” For a town with a population of only 3,100, such an influx of people represents an important economic boon for everyone in the area. The geography and ecology of the Crystal River region is perfect for manatees, which often weigh up to 1,300 pounds. Because...

Bridging the Gap Between Inspections and Decisions
Bridge safety hasn’t always been top of mind for legislators in the United States. The impetus for creating standards and collecting information on how structurally sound the bridges in this country was the collapse of the Silver Bridge in 1967, which spanned the Ohio River between Point Pleasant, WV, and Kanauga, Ohio. The tragedy claimed the lives of 46 people and caused the federal government to quickly mandate regular bridge inspections through the National Bridge Inspection Standards (NBIS)...
Self-Propelled Bridges: Offsite Superstructure Construction Reduces Interruption
The Wisconsin Department of Transportation (WisDOT) is in the midst of a major project to rebuild the I-94 North-South freeway, one of the state’s most frequently used roadways.

In addition to this freeway work, frontage roads and main arteries are being reconstructed and moved. In total, 17 interchanges are being completely redesigned,...
Connected Traffic—Learning from Smartphones to Develop Smart Cities
Back in the waning years of the 19th century, two innovative inventions were beginning their revolutionary paths to change the world. Telephones were just becoming available, and they brought with them the promise of instant and direct voice communication. Meanwhile, growing urban density and horse-drawn traffic created the need for safety and standards to keep streets safe, and the traffic signal was born. Despite not having much in common on the surface, telephony and traffic signals follow...

Rehabilitation with Minimal Interruption
The Wells Street Bridge holds the distinction of being the longest double-deck, double-leaf, bascule bridge built over the Chicago River, and it’s one of two remaining bascule bridges in the city that carries both highway and rail transit on dual levels. The Chicago Transit Authority (CTA) elevated railway occupies the upper level, and vehicle, bicycle and pedestrian traffic are on its lower level. The bridge’s main span is 345 feet long and 72 feet wide, with three lanes of vehicular traffic, a...
