Interstate 375 and Interstate 175

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.

The original alignment of California State Route 1 in San Francisco

In 2019 the Gribblenation Blog Series covered the history of the Hyde Street Pier and the original surface alignment of US Route 101 in San Francisco.  Given the Golden Gate Bridge opened to traffic in May of 1937 coupled with the fact that the Sign State Routes had been announced in August of 1934 there were still some open questions regarding the original highway alignments in San Francisco.  Namely the question of this blog is; where was California State Route 1 prior to the completion of the Golden Gate Bridge?  Thanks the to the discovery of a 1936 Shell Highway Map of San Francisco and the California Highways & Public Works the answer can be conveyed clearly.     Part 1; the history of early California State Route 1 in San Francisco The genesis point for California State Route 1 ("CA 1") in San Francisco dates to 1933.  1933 was significant due to the State Legislature allowing the Division of Highways to assume maintenance of highways in Cities for the first time.

This blog is Part 3 of a three part series on of the Shoreline Highway segment of California State Route 1 and features a drive through Mendocino County.  Part 2 found below features a drive through Marin County.  California State Route 1 the Shoreline Highway Part 2; a drive through Sonoma County Chapter 4; California State Route 1/Shoreline Highway through Mendocino County Upon crossing the Gualala River and entering Mendocino County CA 1 northbound traverses into Gualala at Postmile MEN 1.2. The land which the community of Gualala now sits was part of a 1844 Mexican Land Grant to General Rafael Garcia between the Gualala River and Mal Paso Creek.  After the Mexican-American War the State of California invalidated Garcia's Land Grant which was made it available to homesteaders.  In 1861 Cyrus Robinson filed a claim under the provisions of the 1820 Land Act on land upon which the community of Gualala now sits.  Soon a saloon, hotel and ferry would develop which formed the basis of
