Paper Highways; unbuilt California State Route 100 in Santa Cruz

This edition of Paper Highways examines the unbuilt California State Route 100 in Santa Cruz.



The History of Unbuilt California State Route 100

The route that became CA 100 was added to the State Inventory in 1959 as part of the Freeway & Expressway System as Legislative Route 287.  According to CAhighways.org the initial definition of LRN 287 had it begin at LRN 5 (CA 17) and was defined over the below alignment to LRN 56 (CA 1) through downtown Santa Cruz.

-  Ocean Street
-  2nd Street
-  Chestnut Street

For context the above alignment would required tearing down a large part of the densely populated Santa Cruz.  A modern Google imagine immediately reveals how crazy an alignment following Ocean Street, 2nd Street, and Chestnut Street would have been.


LRN 287 first appears on the 1960 Division of Highways State Map.



In 1961 the definition of LRN 287 was generalized to; from LRN 5 via the beach area in Santa Cruz to LRN 56 west of the San Lorenzo River.  This new more generalized route description of LRN 287 can be first seen on the 1962 Division of Highways State Map.



During the 1964 State Highway Renumbering LRN 287 became CA 100.  The 1964 Division of Highways Map shows a similar route definition to what LRN 287 had in 1961.



CA 100 never had a formal route adoption but somehow it ended up being rescinded anyways in 1975 according to CAhighways.  One of the proposals for a freeway bypass of downtown Santa Cruz was building a parallel route to CA 1 north of Mission Street but it was highly contended locally.  Following U.C. Santa Cruz being established in 1965 some of the proposals for CA 100 had the corridor routed north of downtown and by the School Campus in the foothills of the Santa Cruz Mountains.

Despite the numerous proposals for CA 100 the route has never been Legislatively deleted.  CA 100 still appears on the 2005 Caltrans State Map with the same route definition it had in 1964.



Assuming CA 100 was constructed to the1964 definition it would likely split from the CA 1 freeway/CA 17 expressway junction south via the corridor of Ocean Street.  The theoretical split in CA 100 would likely occur at a shared interchange with CA 17 as seen below from current CA 1.

Breezewood - The Rise and Decline of a Highway Rest Stop

It's the Pennsylvania Turnpike Interchange most people hate - and with a passion.  The Breezewood Interchange - a junction of two Interstates (70 & 76) that became complicated due to archaic rules, rural politics and power, and an unwillingness to change.  At its romanticized best, this small unincorporated community of under 100 residents is a reminder of travel days of the 1950s-1970s; at its worst, it is a gradually dying relic of old motels and services that drivers are forced to slow down and drive through on their way to bigger and more modern destinations.

The Breezewood Interchange is an exception to the rule in the Interstate Highway System.  Depending on your direction, Interstate 70 joins or leaves the Pennsylvania Turnpike (Interstate 76) here.  However, unlike nearly every Interstate junction in the United States - Interstate 70 must traverse on a roughly 1/4 mile stretch of US 30.  A four lane highway complete with traffic lights, center turn lanes to cross traffi…

Just a good old fashioned roadgeeking trip

2020 as we all know has been a year unlike any other.   A number of planned trips for my family and for work have obviously been shelved.   So what can cure that itch to get out and explore.  For me, it was a simple four and a half hour loop north of my home.  
This was for me a good old fashioned roadgeek trip - an explore trip on some roads I hadn't checked out before.  In addition to checking out a few towns along some roads I have been on.  No expectations but the hope of discovering some new things and learn about them.
Route: Local Roads to NC 3 , NC 801, US 601, US 64, NC 901, NC 115, local roads home.
Part of the goal for the trip was to hopefully get additional towns and communities for the Carolina Crossroads project.  Fortunately, the trip didn't disappoint.  For the entire set on flickr - head here.

Bear Poplar was one of the more interesting community names.  Just down the road from here was a nice surprise.  The Mount Ulla community barn quilt is posted on the side o…

California State Route 283; former US Route 101 over the Rio Dell Bridge

This week we examine one of California's shortest State Highways; California State Route 283.  California State Route 283 includes the 1941 Rio Dell Bridge and is a former segment of US Route 101.  The photo below is the Rio Dell Bridge after the 1964 Christmas Floods which wiped out the northern approach span. 


California State Route 283 ("CA 283") is a 0.36 Mile State Highway between modern US Route 101/Redwood Highway and the community of Rio Dell in Humboldt County.  The key feature of CA 283 is the 1941 Rio Dell Bridge which was the second alignment of US Route 101.  The Rio Dell Bridge connected Scotia north over the Eel River via Wildwood Avenue to Rio Dell.  The Rio Dell Bridge is a steel truss design which 1,643.1 feet in length.  The Rio Dell Bridge is also known as; North Scotia Bridge, Eel River Bridge, Scotia-Rio Dell Bridge, Albert Stanwood Murphy Memorial Bridge, and the Eagle Prairie Bridge.  CA 283 is unsigned presently ranks as the second shortest State…
