Interstate 980

This past month I drove the entirety of Interstate 980 upon returning to the San Francisco Bay Area.


I-980 is a short 2 mile long connecting Interstate in downtown Oakland which connects I-880 eastward to I-580/CA 24.

The route that eventually became I-980 was legislatively defined in 1959 a refinement to Legislative Route Number 226 between what was US 50 and CA 17. This change to LRN 226 first appears on the 1960 State Highway Map.

During the 1964 State Highway Renumbering LRN 226 between US 50/I-580 and CA 17 was designated as part of future freeway alignment of CA 24.

By 1970 the route of the CA 24 freeway opened from Caldecott Tunnels west to downtown Oakland.  CA 24 at the time terminated just west of I-580 at Martin Luther King Jr. Way in downtown Oakland.

I-980 was designated as a future Interstate corridor by 1976 according to CAhighways.org.

The current route of I-980 was transferred from CA 24 in 1981.  The change is reflective on the 1982 State Highway City Insert.

By 1986 the full route of I-980 between I-880 and I-580/CA 24 was completed.

My approach to I-980 was from the Jackson Street ramp in downtown Oakland.  From Jackson Street I jumped onto I-880 northbound and took the ramp to I-980 east.  I-980 east is signed as a connecting route to CA 24.






The First Unitarian Church of Oakland, Pardee Home, Oakland China Town and Oakland Convention Center are signed from Exit 1A on I-980 east.  17th Street and former US 40 on San Pablo Avenue are signed as being accessible from Exit 1B.




Access to the Paramount Theatre is signed for Exit 1B.






Traffic is advised past Exit 1B to use I-580 west to reach I-80 from I-980 east.


CA 24 east traffic is advised to stay left from the east terminus of I-980 whereas I-580 traffic exits to the right.  I was headed onto I-580 west and turned off I-980 towards San Francisco.

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n

One Long Drive - Allegheny County's Orange Belt

When I trace my early interest in traveling and the hobby of roadgeeking, I always go back to where I grew up. Pittsburgh, Allegheny County, PA 48, and the Orange Belt. I grew up on Route 48 in Elizabeth Township on the Orange Belt. One of my family's favorite stories of me growing up is when I was around three years old - so 1980 - I told one of my aunts, "It's not that hard to get to our house - we live on the Orange Belt!"  The Allegheny County Belt System is one of the many things that are uniquely Pittsburgh. A series of existing roadways - minor and major - developed in post-World War II Allegheny County to navigate the region. Never intended to be a "beltway" in the modern sense - a full freeway encircling a city - the Allegheny County system is more like a wayfinding system connecting you throughout the county. It is uniquely Pittsburgh - it's been asked about , written about , and videoed .  On a recent visit home, I decided to drive the entire

Mosquito Road Bridge

The Mosquito Road Bridge is a wooden suspension span crossing the South Fork American River of El Dorado County.  The Mosquito Road Bridge incorporates elements in it's foundation which date back to 1867 making it likely the oldest highway bridge in California still is in service for it's original purpose.  The Mosquito Road Bridge can be found approximately 6.5 miles northeast of downtown Placerville.    Author's Note; Gribblenation's 2,000th published blog This blog serves as the 2,000th published entry on the Gribblenation blog site.  Ironically the the 2,000th blog entry closely aligns with the 20th anniversary of Gribblenation.  Adam and Doug recently discussed the history of Gribblenation on the Gribblenation 20th Anniversary Podcast: https://anchor.fm/gribblenation/episodes/Gribblenation-20th-Anniversary-Podcast-ep2nh8 For my own part I (Tom) have been part of Gribblenation since late 2016, it has been an honor to be part of one of the longest lived highway pages
