Arizona State Route 143 the Hohokam Expressway

This past week I fly above Arizona State Route 143 heading eastbound out of Sky Harbor International Airport.  AZ 143 is a freeway I frequented while living in the Phoenix area between 2001 to 2013.


AZ 143 is a short approximately 4 mile Freeway from 48th Street/Interstate 10 north over the Salt River to AZ 202/McDowell Road.  AZ 143 serves essentially as a connector freeway between I-10, AZ 202 and the east entrance of Sky Harbor International Airport.  AZ 143 is known as the Hohokam Expressway.

The legislative history of AZ 143 dates back to the late 1950s when the route was planned as a connector to the planned freeways in Phoenix.  AZ 143 opened to traffic in 1978 as a parkway which essentially the 40th Street entrance to Sky Harbor which was subsequently dismantled to make way for present terminal complex.  During the 1990s AZ 143 was converted to a freeway grade and recently had the interchange with AZ 202 replaced as of 2011.

AZ 143 in present configuration has only a partial ramp freeway-to-freeway interchange with I-10.  At present moment only I-10 east to AZ 143 north has an at-grade interchange while all other travel directions have freeway ramps.  Surface traffic on AZ 143 southbound becomes 48th Street.  The photo below is of I-10 westbound approaching AZ 143 northbound.


Northbound AZ 143 continues briefly beyond AZ 202 where it terminates at-grade at McDowell Road.  This northbound guide sign shows exits; 3B for Sky Harbor, exit 4 for Washington Street and Exit 5 for AZ 202.

Paper Highways; California State Route 1 through the Lost Coast

For all the accolades and praise that California State Route 1 gets for being a top notch coastal highway one fact tends to get overlooked; the highway was never finished!  In this edition of Paper Highways we look at the failed path of California State Route 1 through the Lost Coast.



Part 1; the history of Legislative Route 56 and California Route 1 through the Lost Coast

The Lost Coast region consists of the undeveloped coastal areas of Humboldt County, Mendocino County, and the King Range.  The Lost Coast region roughly spans from near Rockport in Mendocino County north to Ferndale of Humboldt County.  The Lost Coast region is known for having rugged terrain which rivals what is seen in Big Sur.  The Lost Coast has several small communities such as; Shelter Cove, Whitehorn, and Petrolia.

In 1933 Legislative Route 56 was extended south to LRN 2 (US 101) near Las Cruces and north to Ferndale to LRN 1 (also US 101).  Prior to 1933 the legislative description of LRN 56 had it's nort…

Where the hell is Hill Valley? (US Route 8 south/US Route 395 east)

Recently I made a visit to Universal Studios near Los Angeles.  While on the back lot tour I came across a piece of infamous movie-borne fictional highway infamy; the location of town square of Hill Valley, California on US Route 8/US Route 395.


The above photo is part of the intro scene to the first Back-to-the-Future movie which was set in 1985. To anyone who follows roadways the signage error of US 8 meeting US 395 in California is an immediately notable error.  For one; US 8 doesn't even exist anywhere near California with present alignment being signed as an east/west highway between Norway, Michigan and Forest Lake, Minnesota.  To make matters worse US 8 is signed as a southbound route and US 395 (a north/south highway) is signed as an eastbound route.  At minimum the cut-out US 8 and US 395 shields somewhat resemble what Caltrans used in the 1980s.

Assuming Hill Valley is located on what would have been US 395 by 1985 what locales would be a viable real world analog?  US 39…

US Route 99 to Visalia?...

Something that I noticed awhile back while doing map research regarding US Route 99 in Fresno was that the highway intended to be originally routed through the City of Visalia.



The early originally planned alignment of US Route 99 in Visalia

To be clear US 99 was never actually routed through Visalia and ended up bypassing the City in favor of a direct route from Goshen southeast to Tulare.  US 99 within San Joaquin Valley was aligned over Legislative Route 4 which in turn was added to the State Highway System as part of the 1909 First State Highway Bond Act.  LRN 4 for a time was aligned through Visalia via; Mineral King Avenue, Main Street, and Mooney Boulevard.  This early alignment of LRN 4 through Visalia can be seen on the 1924 Division of Highways State Map.


The initial draft of the US Route System was approved by the Secretary of Agriculture during November of 1925.  The US Route System with in California was approved by California Highway Commission with no changes recommended…
