US Route 23 Business in Ann Arbor, Michigan

By


US Route 23 Business in Ann Arbor was a corridor established in 1959 over much of the original surface routing of mainline US Route 23.  From Mainline US Route 23 the Business Route follows M-14 over the Huron River, Main Street, Huron Street and Washtenaw Avenue.  The general surface routing was inherited from M-65 and M-17 prior to the establishment of the US Route System in 1926.  Pictured as the blog cover is southbound Main Street in downtown Ann Arbor approaching Huron Street.  




Part 1; the history of US Route 23 in Ann Arbor

The routing now occupied by US Route 23 Business in Ann Arbor was originally part of M-17 and M-65.  M-17 and M-65 were original State Trunklines designated during 1919.  The westbound Trunkline followed Washtenaw Avenue, Huron Street and Jackson Avenue through Ann Arbor.  M-65 entered Ann Arbor via Main Street and terminated at M-17 at Huron Street. 

M-65 and M-17 can be seen intersecting in downtown Ann Arbor on the 1924 Rand McNally Auto Trails Map of Michigan.  


The US Route System was formally established by the American Association of State Highways Officials (AASHO) on November 11, 1926.  Downtown Ann Arbor served as the junction of US Routes 23 and 12.  US Route 23 southbound entered the city following what was M-65 via Main Street and intersected US Route 12 at Beakes Street.  Both highways multiplexed south along Main Street and split at Huron Street.  US Route 12 continued west on Huron Street towards Jackson Avenue whereas US Route 23 continued east to Washtenaw Avenue past Ann Arbor city hall.  US Route 23 continued southeast via Washtenaw Avenue to Ypsilanti.  

US Route 23 and US Route 12 can be seen passing through Ann Arbor on the 1927 Rand McNally Junior Map of Michigan. 


The Michigan State Highway Department submitted an application to the AASHO dated May 4, 1959, requesting numerous changes to the routing of US Route 23.  Included in the request was a submission to relocated US Route 23 onto the then new eastern Ann Arbor bypass freeway and the establishment of a Business Route on the original surface alignment.  The request was approved by the AASHO Executive Committee on June 11, 1959.  







US Route 23 Business can be seen passing through the former mainline surface routing in downtown Ann Arbor on the 1965 United States Geological Survey Map of eastern Ann Arbor.  




Part 2; a drive on US Route 23 Business in Ann Arbor

US Route 23 Business silently follows M-14 west of the US Route 23/M-14 (US Route 23 Exit 45) over the Huron River to Exit 3 onto Main Street.  



US Route 23 Business follows Main Street towards downtown Ann Arbor.  At Kingsley Street/Beakes Street the highway intersects what was the original routing of US Route 12.  



US Route 23 Business continues south on Main Street and makes a left-hand turn onto Huron Street.  US Route 23 Business southbound is multiplexed with Interstate 94 Business along Huron Street and Washtenaw Avenue.

Did Caltrans just kill the G26 cutout US Route shields?

By
The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...

Hawaii Route 50

By
Hawaii Route 50 is the longest Sign Route on the island of Kauai at 32.6 miles.  The entirety of Hawaii Route 50 is overlaid atop Kaumualii Highway from Lihue west to the Pacific Missile Range Facility at Barking Sands. Hawaii Route 50 is one of the original 1955-era State Highway designations on Kauai.  Much of the Kaumualii Highway corridor was constructed during the sugar plantation boom of the late Hawaiian Kingdom.  The first tee beam bridge in Hawaii would be constructed along the Kaumualii Highway in 1911 at the Hanapepe.  Much of this highway would be modernized to two-lane standards through the 1930s and 1940s.

Ghost Town Tuesday; Nichols, FL

By
A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida.  One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region.  For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate.  Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century.  Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area.  The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...
