Castillo de San Marcos National Monument


The Castillo de San Marcos has guarded St. Augustine for over 325 years.  The coquina stone structure took 23 years to build (1672-1695) and would see service until the turn of the 20th Century.  The fort would be under the command of four different countries, but it was never taken by military force.

The castillo would serve as the ultimate permanent replacement of nine prior wooden forts that existed in St. Augustine the century prior to the start of San Marcos' construction.  The fort was attacked twice by the British in the early 18th century, 1702 and 1739, yet the fort and the city would not be captured.  The fort would finally fall into British hands - and renamed Fort St. Mark - not by force, but by treaty in 1763.  In the Paris Treaty signed to end the Seven Years War, Britain gained Florida from the Spanish in return for Cuba and the Philippines.  A second Treaty of Paris would return Florida and the fort to the Spanish in 1784.

Spain would return the fort's name to Castillo de San Marcos and would hold the fort and Florida until 1821.  On July 20 of that year, the Spanish government would cede all of Florida to the United States.  The Americans would rename the base Fort Marion in honor of Revolutionary War General Francis Marion.   In December 1860 when Florida seceded from the Union and joined the Confederacy, Fort Marion was given to the Confederates in return for a receipt for the fort and all the contents inside.  The Union would regain the fort on March 11, 1862 after Confederate forces abandoned the fort and the citizens of St. Augustine surrendered to preserve their city.


For the remainder of the fort's operation , it served predominantly as a military prison.  Native Americans and deserters during the Spanish-American War would be imprisoned here.  In 1924, the fort was declared a National Monument, and nine years later it would be transferred to the National Park Service.  In 1942, Fort Marion was renamed Castillo de San Marcos in honor of its and the state's Spanish heritage. Today, the fort is one of the major tourist attractions in St. Augustine.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l...

Massena Center Suspension Bridge

The Massena Center Bridge, also known as the Holton D. Robinson Bridge, has had quite the tumultuous history. Situated on the Grasse River just east of Massena, New York in the hamlet of Massena Center, the Massena Center Bridge is a reminder of the efforts the community has made in order to connect over the river. The first and only other known bridge to be built at Massena Center was built in 1832, but that bridge was never long for this world. During the spring of 1833, the Grasse River dammed itself due to an ice dam, flooded and lifted the bridge off its foundation, destroying the bridge in the process.  The floods were frequent in the river during the spring, often backing up the river from Hogansburg and past Massena Center, but not to nearby Massena. After the first bridge disappeared, local residents had to resort to traveling seven miles west to Massena to cross the next closest bridge, and that was no easy task for a horse and buggy. However, it was many decades befo...

The Dead Man's Curve of Interstate 90 and Innerbelt Freeway in Cleveland

"Dead Man's Curve" refers to the transition ramp Interstate 90 takes between Cleveland Memorial Shoreway onto the Innerbelt Freeway in downtown Cleveland, Ohio.  Said curve includes a sharp transition between the two freeways which is known for a high rate of accidents.  Currently the curve (not officially named) has a 35 MPH advisory speed and numerous safety features intended to mitigate crashes.  When the Interstate System was first conceived during 1956, Interstate 90 was intended to use the entirety Cleveland Memorial Shoreway and connect to the Northwest Freeway through Lakewood.  The Innerbelt Freeway was initially planned as the northernmost segment of Interstate 71.  The extension of Cleveland Memorial Shoreway west of Edgewater Park was never constructed which led to Interstate 90 being routed through the Innerbelt Freeway.   Part 1; the history of Cleveland's Innerbelt Freeway and Deadman's Curve The Federal Aid Highway Act of 1956 was signe...
