Hawaii Route 310


Hawaii Route 310 is a 3.6-mile State Highway located on the Island of Maui.  Hawaii Route 310 begins at the junction of Hawaii Route 31/Hawaii Route 311 in Kihei and heads westward along Maalaea Bay toward a terminus at Hawaii Route 30.  Hawaii Route 310 follows North Kihei Road through it's entire routing and was once part of Hawaii Route 31.  The cover photo of this blog is an eastward view of Hawaii Route 310 facing towards Maalaea Bay, Kihei and Haleakala.  


Part 1; the history of Hawaii Route 310

The Island of Maui seemingly was not part of the original World War II era Hawaii Route System.  Circa 1955 the United States Bureau of Public Roads renumbered the Hawaii Route System.  The 1955 Hawaii Route Renumbering saw most of the conventions utilized by the current Hawaii State Route System established.  Primary Hawaii Routes were given two-digit numbers whereas Secondary Hawaii Routes were given three-digit numbers.  The Hawaii Routes were assigned in sequence for what Island/County they were located on coupled with what Federal Aid Program number they were tied to.  In the case of the Island of Maui it was assigned numbers in the range of 30-40.  

Hawaii Route 31 as originally defined began at Hawaii Route 30 and followed what is now North Kihei Road and South Kihei Road into Kihei.  From Kihei the routing of Hawaii Route 31 is unclear and may have had a gap between Makena east towards Hawaii Route 37/Kula Highway.  From Hawaii Route 37/Kula Highway the routing of Hawaii Route 31 continued east via Piilani Highway towards Hawaii Route 36 in Hana.  Hawaii Route 31 as originally configured can be seen on the 1959 Gousha Map of Hawaii.  Hawaii Route 31 is noted to be a secondary highway.


During the 1960s the Hawaii Route system was simplified, and numerous segments of important roadways were adopted from the counties.  According hawaiihighways.com North Kihei Road was adopted as State Highway whereas South Kihei Road remained maintained by Maui County.  According to hawaiihighways.com North Kihei Road was reassigned as Hawaii Route 310 but remained field signed as Hawaii Route 31.  

During 1981 the first segment of the State Maintained Hawaii Route 31 on western Piilani Highway in Kihei opened.  During April 1981 Hawaii Route 310 was extended 0.1 miles to reach the new alignment of Hawaii Route 31 in Kihei at western Piilani Highway.  


Part 2; a drive on Hawaii Route 310

Eastbound Hawaii Route 310 originates from Hawaii Route 30/Honoapiilani Highway near Maalaea.  


Hawaii Route 310 eastbound descends towards the waters of Maalaea Bay.  Traffic on Hawaii Route 310 can access Kealia Pond the and Kealia Coastal Boardwalk.  








From Kealia Pond, Hawaii Route 310 continues eastward and intersects former Hawaii Route 31 South Kihei Road.  





Hawaii Route 310 eastbound terminates at the intersection of Hawaii Route 31 and Hawaii Route 311 at the outskirts of Kihei.

The rogue G28-2 California State Highway Spades

In this short blog we look at the somewhat rare but not unheard-of rogue G28-2 California State Highway Spades affixed to guide signs. Part 1; what is the G28-2 California State Highway Spade?  The  Caltrans Manual of Uniform Traffic Control Devices Sign Chart from 2014  ("Caltrans MUTCD") dictates the types of signs and highway shields permitted for traffic control use in California.  California is known for it's more ornate cut-out shields which are used for, US Routes, Interstate Highways, and State Routes.  These shields are intended to be applied as standalone reassurance signs but aren't explicitly limited to said function and occasionally appear in error on guide signs.  The common shields which are typically found through California are: US Route:  G26-2 Interstate:  G27-2 State Highway:  G28-2 The Caltrans MUTCD provides alternative shields for, US Routes, Interstate Highways, and State Routes.  These alternative shields are intended for guide sign usage.  Th

Former Greater Pittsburgh International Airport Terminal

For just over four decades, the former main terminal of Greater Pittsburgh International Airport was the city's gateway to the world.  Located nearly 20 miles west of Downtown Pittsburgh, the Joseph Hoover-designed terminal would see millions of travelers pass through its doors.  Known best for the terrazzo compass in the main lobby, the terminal had many other distinguishing features.  The well-landscaped entrance led up to the curved stepped design of the terminal. Each level of the terminal would extend out further than the other allowing for numerous observation decks.  The most popular observation deck, the "Horizon Room", was located on the fourth floor. The former Greater Pittsburgh Airport Terminal - October 1998 From when it opened in the Summer of 1952 until its closing on September 30, 1992, the terminal would grow from a small regional airport to the main hub for USAir.  The terminal would see numerous expansions and renovations over its 40 years of

Highways in and around Old Sacramento; US 40, US 99W, CA 16, CA 24, CA 70, CA 99, CA 275, and more

This past weekend I was visiting the City of Sacramento for a wedding.  That being the case I decided to head out on a morning run through Old Sacramento, Jibboom Street Bridge, I Street Bridge, Tower Bridge, and path of US Route 40/US Route 99W towards the California State Capitol.  My goal was to retrace the paths of the various highways that once traversed the Old Sacramento area.
