Interstate 375 and Interstate 175

By
While I was finishing a photo-clinch of Interstate 275 I decided to make two short detours in St. Petersburg to do the same with Interstate 375 and Interstate 175.


I-375 is a 1.2 mile Interstate carrying the hidden Florida State Road 592 designation which spans from I-275 east to US 19A in downtown St. Petersburg.  I-175 just to the south is a 1.3 mile Interstate carrying the hidden FL 594 designation from I-275 to FL 687.

I-375 in it's present configuration opened to traffic in 1979.  Originally I-375 was slated to extend west of I-275 to a toll road facility that would be built to connect northward to Clearwater.  Ultimately these aspirations failed leaving something of a lame duck feeder freeway that I-375 is today.

My approach to I-375 was on I-275 southbound.  I took I-275 Exit 23A and turned onto I-375 east towards downtown St. Petersburg.


I-375 east is signed as the "C. Bette Wimbush Highway."


The view of downtown St. Petersburg on the ramp to I-375 is actually pretty scenic.


Traffic to Tropicana Field is directed to exit onto Martin Luther King Jr. Street while US 92/4th Street traffic is directed to continue eastward on I-375.




Traffic is given copious warning that I-375 east is about to end.  I-375 east ends at US 19A on 4th Avenue on unsigned FL 595 just short of US 92 at 4th Street.  I've often found it odd that US 92 was never extended over FL 595 westward to the mainline US 19 which would largely clear up the strange terminus points.  Even extending US 92 south on FL 687 to I-175 would make more sense.





I looped back onto I-375 west from US 19A on 5th Avenue.



There isn't much on I-375 west aside from a direct connection back to I-275.




I-175 opened to traffic in it's current configuration in 1980.  Originally the route that became I-175 was intended to become part of the much larger Pinellas Belt Expressway which would have extended west of I-275.

I headed south on I-275 to the junction with I-175 east at Exit 22.


Tropicana Field traffic is directed to use Martin Luther King Jr. Street/8th Street.  Downtown traffic to FL 687 on 4th Street is directed to stay on I-175 east.




The John Hopkins All Children Hospital is signed off the 6th Street Exit on I-175 east.



As I-175 east ends in downtown St. Petersburg at FL 687 on at 4th Street traffic is advised that the Dali Museum and Mahaffey Theater are ahead.




Traffic can almost immediately loop back onto I-175 east via 4th Street, 4th Avenue and 6th Street.





I-175 west essentially is a direct shot back to I-275.

Grand Loop Road of Yellowstone National Park

By
  Grand Loop Road is a 140 mile loop highway which traverses the interior of Yellowstone National Park.  Grand Loop Road connects all of the major attractions and geological features of Yellowstone National Park along with the entrance roads.  Grand Loop Road is a seasonal highway and despite some conjecture never has been part of the US Route System.   Part 1; the history of Grand Loop Road The majority of history pertaining to Grand Loop Road was taken from the below National Park Service article: Historic Roads - Yellowstone National Park (U.S. National Park Service) (nps.gov) Yellowstone was declared the first National Park of the United States on March 1st, 1872.  The first real highway to access Yellowstone National Park came in 1873 when a tolled facility was constructed from Bozeman, Montana via Yankee Jim Canyon to Mammoth Hot Springs.  Numerous attempts were made to fund construction of roadway infrastructure during the early years of Yellows...

The last 1956-63 era California Sign State Route Spade?

By
Along southbound California State Route 170 (the Hollywood Freeway Extension) approaching the Hollywood Freeway/Ventura Freeway interchange a white California State Route 134 Sign State Route Spade can be observed on guide sign.  These white spades were specifically used during the 1956-63 era and have become increasingly rare.  This blog is intended to serve as a brief history of the Sign State Route Spade.  We also ask you as the reader, is this last 1956-63 era Sign State Route Spade or do you know of others?  Part 1; the history of the California Sign State Route Spade Prior to the Sign State Route System, the US Route System and the Auto Trails were the only highways in California signed with reassurance markers.  The creation of the US Route System by the American Association of State Highway Officials during November 1926 brought a system of standardized reassurance shields to major highways in California.  Early efforts to create a Sign State Route ...

California State Route 70; the Feather River Highway

By
From 2017 through to early 2019 I drove the majority of the California State Route 70; the Feather River Highway from CA 89 southwest to CA 99. CA 70 is an approximately 178.5 mile state highway which starts at US 395 near the Nevada State Line and travels west through the Feather River Canyon to CA 99.  CA 70 is often referred to as the Feather River Highway" given it's close association with the river.  Historically CA 70 was previously signed as US 40A and CA 24.  The Legislative Routes prior to the 1964 California Highway Renumbering that made up the current route of CA 70 are as follows: -  Legislative Route Number 21 from US 395 westward to Oroville. -  LRN 87 from Oroville south to Marysville. -  LRN 232 from Marysville to the current junction with CA 99.  CA 70 was even dual signed with CA 99 into Sacramento on what was LRN 232 for a time. The change from US 40A/LRN 21/LRN 87/LRN 232 can be seen by comparing the 1963 State Highway Ma...
