Hawaii Route 3400 (the amalgamation of former Hawaii Route 34 and former Maui County Route 341)


Hawaii Route 3400 is a 2.6-mile State Highway located on the Island of Maui in the Wailuku and Kahului areas.  Hawaii Route 3400 is comprised of portions which were once part of Hawaii Route 34 on Kahului Beach Road and Maui County Route 341 on Waiehu Beach Road.  Modern Hawaii Route 3400 now bridges Hawaii Route 32 at Kaahumanu Avenue in Kahului north to Hawaii Route 340/Maui County 330 at Kahekili Highway near Wailuku. 


Part 1; the evolution of Hawaii Route 34 and Maui County Route 341 into Hawaii Route 3400

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 34 was aligned from Hawaii Route 32 at Kaahumanu Avenue in Kahului west through Wailuku on a partially completed downtown bypass via lower Main Street and approximately half a mile of Waiale Road.  Hawaii Route 34 was connected to Hawaii Route 30 south of downtown Wailuku via non-state-maintained Koa Drive.  Maui County Route 341 was aligned north from Hawaii Route 34 at lower Main Street via what is now Waiehu Beach Road and Lower Waiehu Beach Road to Waiehu Beach Park.  The original configurations of Hawaii Route 34 and Maui County Route 341 can be seen on the 1955 United States Geological Survey map of Wailuku.  

According hawaiihighways.com a 1967 Hawaii Department of Transportation document recommended the removal of Hawaii Route 34 from the Federal-Aid Highway System and by proxy State Highway System.  This measure seems to have been taken due to Koa Drive never been taken on as a State maintained facility which meant Hawaii Route 34 never fully functioned as the bypass of downtown Wailuku it was intended to be.  

Despite being a mainline State Highway, it appears Hawaii Route 34 may have been always signed with "bypass" placards.  A 2001 era image of a Hawaii Route 34 shield along with a bypass placard can be seen on hawaiihighways.com here.  

1.5 miles of Maui County Route 341 (Waiehu Beach Road) from lower Main Street to Waiehu Stream and 4.3 miles of Kahekili Highway north of Waiehu Stream were to Camp Maluhia were recommended to be added to the State Highway System.  This led to construction of a new connecting branch of Waiehu Beach Road directly to Kahekili Highway.  This new construction led to the designation of Hawaii Route 340 which followed Kahului Beach Road (formerly lower Main Street) 1.1 miles, Waiehu Beach Road for 1.5 miles and replacing Hawaii Route 33 over Kahekili Highway for 4.3 miles.  Hawaii Route 340 can be seen on the 1983 United States Geological Survey Map of the Wailuku area.  



It is unclear when Hawaii Route 3400 replaced Hawaii Route 340 between Kaahumanu Avenue and Kahekili Highway.  Hawaii Route 3400 is shown to be interchange with Hawaii Route 340 on the 2017 United State Geological Survey map of the Wailuku area.  Hawaii Route 340 shields strangely are occasionally in place along modern Hawaii Route 3400.  


Part 2; a drive on Hawaii Route 3400

Hawaii Route 3400 begins via a right-hand turn from the terminus of Maui County Route 330 on Kahekili Highway onto Waiehu Beach Road.  



Hawaii Route 3400/Waiehu Beach Road eastbound intersects former Maui County Route 341 at Lower Waiehu Beach Road.  

Hawaii Route 3400/Waiehu Beach Road continue east to Kahului Beach Road and lower Main Street.  Hawaii Route 3400 makes a left hand turn onto Kahului Beach Road whereas Hawaii Route 34 would have once gone in both directions.  For unknown reasons the approach to Kahului Beach Road and lower Main Street is signed "junction Hawaii Route 340."


Hawaii Route 3400 continues east via Kahului Beach Road where it terminates at Hawaii Route 32/Kaahumanu Avenue (GSV image used).

Sunshine Bridge (Donaldsonville, LA)

Located about halfway between Baton Rouge and New Orleans in southern Louisiana, the Sunshine Bridge spans the lower Mississippi River near the city of Donaldsonville as part of the longer Louisiana Highway 70 corridor, which connects Interstate 10 and Airline Highway (US 61) with US 90 in Morgan City. In the years following World War II, the only bridges across the lower Mississippi River in Louisiana were located in the area of the state’s two largest cities – Baton Rouge and New Orleans. Postwar agricultural and industrial development along the river in this region led to the planning of a series of infrastructure projects in southern Louisiana that were aimed at spurring this development and modernization of the Delta region. One of these projects was known as the Acadian Thruway and was developed in the 1950s as a toll road intended to connect greater New Orleans with Lafayette and points west while providing a high-speed bypass of the Baton Rouge metro area. The Thruway, which

Old River Lock & Control Structure (Lettsworth, LA)

  The Old River Control Structure (ORCS) and its connecting satellite facilities combine to form one of the most impressive flood control complexes in North America. Located along the west bank of the Mississippi River near the confluence with the Red River and Atchafalaya River nearby, this structure system was fundamentally made possible by the Flood Control Act of 1928 that was passed by the United States Congress in the aftermath of the Great Mississippi River Flood of 1927 however a second, less obvious motivation influenced the construction here. The Mississippi River’s channel has gradually elongated and meandered in the area over the centuries, creating new oxbows and sandbars that made navigation of the river challenging and time-consuming through the steamboat era of the 1800s. This treacherous area of the river known as “Turnbull’s Bend” was where the mouth of the Red River was located that the upriver end of the bend and the Atchafalaya River, then effectively an outflow

Natchez-Vidalia Bridge (Natchez, MS)

  Located about halfway between Baton Rouge and Vicksburg near the city of Natchez, the Natchez-Vidalia Bridge crosses the lower Mississippi River between southwest Mississippi and northeastern Louisiana at the city of Vidalia. This river crossing is a dual span, which creates an interesting visual effect that is atypical on the Mississippi River in general. Construction on the original bridge took place in the late 1930s in conjunction with a much larger parallel effort by the U.S. Army Corps of Engineers to strengthen the area’s flood protection and levee system along the Mississippi River. One of the more ambitious aspects of this plan was to relocate the city of Vidalia to a location of higher ground about one mile downriver from the original settlement. The redirection of the river through the Natchez Gorge (which necessitated the relocation of the town) and the reconstruction of the river’s levee system in the area were undertaken in the aftermath of the Great Flood of 1927, wh
