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: The Unbuilt New Orleans Bypass (Proposed I-410)

  There are many examples around the United States of proposed freeway corridors in urban areas that never saw the light of day for one reason or another. They all fall somewhere in between the little-known and the infamous and from the mundane to the spectacular. One of the more obscure and interesting examples of such a project is the short-lived idea to construct a southern beltway for the New Orleans metropolitan area in the 1960s and 70s. Greater New Orleans and its surrounding area grew rapidly in the years after World War II, as suburban sprawl encroached on the historically rural downriver parishes around the city. In response to the development of the region’s Westbank and the emergence of communities in St. Charles and St. John the Baptist Parishes as viable suburban communities during this period, regional planners began to consider concepts for new infrastructure projects to serve this growing population.  The idea for a circular freeway around the southern perimeter of t

Hernando de Soto Bridge (Memphis, TN)

The newest of the bridges that span the lower Mississippi River at Memphis, the Hernando de Soto Bridge was completed in 1973 and carries Interstate 40 between downtown Memphis and West Memphis, AR. The bridge’s signature M-shaped superstructure makes it an instantly recognizable landmark in the city and one of the most visually unique bridges on the Mississippi River. As early as 1953, Memphis city planners recommended the construction of a second highway bridge across the Mississippi River to connect the city with West Memphis, AR. The Memphis & Arkansas Bridge had been completed only four years earlier a couple miles downriver from downtown, however it was expected that long-term growth in the metro area would warrant the construction of an additional bridge, the fourth crossing of the Mississippi River to be built at Memphis, in the not-too-distant future. Unlike the previous three Mississippi River bridges to be built the city, the location chosen for this bridge was about two

Memphis & Arkansas Bridge (Memphis, TN)

  Like the expansion of the railroads the previous century, the modernization of the country’s highway infrastructure in the early and mid 20th Century required the construction of new landmark bridges along the lower Mississippi River (and nation-wide for that matter) that would facilitate the expected growth in overall traffic demand in ensuing decades. While this new movement had been anticipated to some extent in the Memphis area with the design of the Harahan Bridge, neither it nor its neighbor the older Frisco Bridge were capable of accommodating the sharp rise in the popularity and demand of the automobile as a mode of cross-river transportation during the Great Depression. As was the case 30 years prior, the solution in the 1940s was to construct a new bridge in the same general location as its predecessors, only this time the bridge would be the first built exclusively for vehicle traffic. This bridge, the Memphis & Arkansas Bridge, was completed in 1949 and was the third
