Minnesota is often called the Land of 10,000 Lakes, but it could also be called the Land of 20,000 Bridges. /

During the early days of the state, the Mississippi River and its many tributaries barred and disrupted transportation and commerce. To span these obstacles, communities battled to build and maintain bridges. Their efforts created a variety of bridge designs and purposes—from small hiking and biking bridges to concrete beams across rural rivers. Across the area, one can behold wonders like the beautiful Stone Arch Bridge, the La Crescent Swing Bridge, the Point Douglas Drawbridge, the elegant Winona Main Channel Bridge as well as other massive structures crossing the Mississippi.

Studying and photographing these amazing structures, local author Steve Gardiner celebrates the innovation and determination of Southeast Minnesota./      

With fewer than a thousand remaining in the United States, the covered bridges of Alabama are an important relic of the paths our ancestors took.

Alabama's covered bridges are reminiscent of a more romantic time, when people rode in horse-drawn buggies and couples stole kisses beneath their roofs. But they are also keepers of history - structures built by former slaves and Civil War soldiers. Such places are steeped in legend, including tales of ghostly children and the hanging of a sheriff turned outlaw. Just eleven historic covered bridges survive in Alabama - the oldest dating to the 1850s - but dozens of more recently constructed spans dot the landscape. Wil Elrick and Kelly Kazek provide photos and detailed information on more than fifty Alabama bridges, reveal the fate of the state's lost bridges and delve into the haunting legends surrounding these nostalgic structures.

Newport is a premier destination, but getting to the city has not always been easy.

For three centuries, ferries crossed Narragansett Bay's East Passage. That all changed on June 28, 1969, the day the Newport Bridge opened, and it closed the last remaining gap between Aquidneck and Conanicut Islands. Proponents of the bridge persevered political squabbles and delays for twenty-five years following World War II to make it a reality. The longest suspension bridge in the region incorporated several new technologies and construction techniques and changed the face of Rhode Island. Author James Ricci details the trials and tribulations that produced an iconic bridge.
