Florida Friday; Bridges in Jacksonville

Back in 2013 I was working out of Jacksonville on occasion.  That being the case I was able to checkout much of the bridge network crossing the St. Johns River. 

The Mathews Bridge is a cantilever bridge carrying Florida State Road 115 over the St. Johns River from downtown Jacksonville.  The Mathews Bridge opened in 1953 and is approximately 7,736 feet in length.  Despite the maximum 152 foot clearance down to the St. Johns River the structure was struck by a military ship in 2013 which led to a one month closure. 


South of the Mathews Bridge is the Hart Bridge.   The Hart Bridge is a truss bridge carrying FL 228 and US 1A from downtown Jacksonville over the St. Johns River.  The Hart Bridge opened in 1967 and is approximately 3,844 feet in length.  The maximum clearance for the Hart Bridge above the St. Johns River is 141 feet.


Northeast of the Hart and Mathews Bridges is the Dames Point Bridge carrying I-295 traffic over the St. Johns River.  The Dames Point Bridge is a cable stayed structure which was completed in 1989.  The Dames Point Bridge is approximately 10,646 feet in length and has a maximum clearance of 175 feet.

Route 75 Tunnel - Ironton, Ohio

In the Ohio River community of Ironton, Ohio, there is a former road tunnel that has a haunted legend to it. This tunnel was formerly numbered OH 75 (hence the name Route 75 Tunnel), which was renumbered as OH 93 due to I-75 being built in the state. Built in 1866, it is 165 feet long and once served as the northern entrance into Ironton, originally for horses and buggies and later for cars. As the tunnel predated the motor vehicle era, it was too narrow for cars to be traveling in both directions. But once US 52 was built in the area, OH 93 was realigned to go around the tunnel instead of through the tunnel, so the tunnel was closed to traffic in 1960. The legend of the haunted tunnel states that since there were so many accidents that took place inside the tunnel's narrow walls, the tunnel was cursed. The haunted legend states that there was an accident between a tanker truck and a school bus coming home after a high school football game on a cold, foggy Halloween night in 1

US Route 299 and modern California State Route 299

US Route 299 connected US Route 101 near Arcata of Humboldt County east across the northern mountain ranges of California to US Route 395 in Alturas of Modoc County.  US Route 299 was the longest child route of US Route 99 and is the only major east/west highway across the northern counties of California.  US Route 299 was conceptualized as the earliest iteration of what is known as the Winnemucca-to-the-Sea Highway.  The legacy of US Route 299 lives on today in the form of the 307 mile long California State Route 299.   Featured as the cover of this blog is the interchange of US Route 101 and US Route 299 north of Arcata which was completed as a segment of the Burns Freeway during 1956.   Part 1; the history of US Route 299 and California State Route 299 The development of the State Highways which comprised US Route 299 ("US 299") and later California State Route 299 ("CA 299") began with 1903 Legislative Chapter 366 which defined the general corridor of the Trinit

Former California State Route 190 at the bottom of Lake Success

East of the City of Porterville the alignment of California State Route 190 follows the Tule River watershed into the Sierra Nevada Mountains.  In modern times California State Route 190 east of Porterville climbs south of the Lake Success Reservoir towards Springville.  Much of the original alignment of California State Route 190 within the Lake Success Reservoir can still be hiked, especially in drier years.  Pictured above is the original alignment of California State Route 190 facing northward along the western shore of Lake Success.  Part 1; the history of California State Route 190 through Lake Success The corridor of California State Route 190 ("CA 190") east of Porterville to Springville follows the watershed of the Tule River.  The Tule River watershed between Porterville and Springville would emerge as a source of magnesite ore near the turn of the 20th Century.  The magnesite ore boom would lead to the development of a modern highway in the Porterville-Springville
