Former California State Route 106


California State Route 106 was a short lived post-1964 Sign State Route.  California State Route 106 was defined over what had been Legislative Route Number 190 between California State Route 38 near Redlands to California State Route 30 near Highland via Boulder Avenue and Orange Street.  California State Route 106 was consolidated into California State Route 30 via 1972 Legislative Chapter 1216. 



The history of California State Route 106

What was to become California State Route 106 (CA 106) entered the State Highway System during 1933 as part of Legislative Route Number 190 (LRN 190).  The original definition of LRN 190 was as follows: 

"LRN 9 (US Route 66) near San Dimas to LRN 26 (US Route 99) near Redlands via Highland Avenue." 

LRN 190 was not assigned one of the original Sign State Routes which were announced in the August 1934 California Highways & Public Works.  The future alignment of CA 106 appears on the 1934 Division of Highways Map as LRN 190 on Orange Street between Highland-Redlands.  


LRN 190 on Orange Street appears on the 1935 Division of Highways Map of San Bernardino County.  Between Highland Avenue and Orange Street the alignment of LRN 190 is shown making numerous jogs, including Baseline Street.  


The November/December 1947 California Highways & Public Works announced the construction and paving of a new bridge on LRN 190/Baseline Street had been budgeted for the 1948-49 Fiscal Year. 


A contract to construct the realignment of LRN 190 between Baseline Street and Orange Street was announced in the November/December 1948 California Highways & Public Works.  


The realignment of LRN 190 connecting Highland Avenue to Orange Street via Boulder Avenue appears on the 1950 Division of Highways Map.  


The January/February 1955 California Highways & Public Works announced a contract to expand LRN 190 between CA 30/LRN 207 to Baseline Street to a four-lane divided highway.  


An adopted freeway alignment for LRN 190 between Highland and Redlands was announced in the July/August 1963 California Highways & Public Works.  The Highland-Redlands Freeway alignment of LRN 190 was selected by the California Highway Commission during their May-June 1963 meetings.




As part of the 1964 State Highway Renumbering the Legislative Route Numbers were dropped in favor of field signage.  Legislative Route Numbers which didn't have Sign State Routes were assigned them.  In the case of LRN 190 between Highland and Redlands it was assigned as CA 106.  The original definition of CA 106 was "Route 38 near Redlands to Route 30 near Highland."  CA 106 appears for the first time on the 1964 Division of Highways Map.



CA 106 was short lived as 1972 Legislative Chapter 1216 transferred it to a realigned CA 30.  CA 30 can be seen replacing CA 106 between Highland and Redlands on the 1975 Caltrans Map.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l

Mines Road

Mines Road is an approximately twenty-eight-mile highway located in the rural parts of the Diablo Range east of the San Francisco Bay Area.  Mines Road begins in San Antonio Valley in Santa Clara County and terminates at Tesla Road near Livermore of Alameda County.  The highway essentially is a modern overlay of the 1840s Mexican haul trail up Arroyo Mocho known as La Vereda del Monte.  The modern corridor of Mines Road took shape in the early twentieth century following development of San Antonio Valley amid a magnesite mining boom.  Part 1; the history of Mines Road Modern Mines Road partially overlays the historic corridor used by La Vereda del Monte (Mountain Trail).  La Vereda del Monte was part of a remote overland route through the Diablo Range primarily used to drive cattle from Alta California to Sonora.  The trail was most heavily used during the latter days of Alta California during the 1840s. La Vereda del Monte originated at Point of Timber between modern day Byron and Bre

Route 75 Tunnel - Ironton, Ohio

In the Ohio River community of Ironton, Ohio, there is a former road tunnel that has a haunted legend to it. This tunnel was formerly numbered OH 75 (hence the name Route 75 Tunnel), which was renumbered as OH 93 due to I-75 being built in the state. Built in 1866, it is 165 feet long and once served as the northern entrance into Ironton, originally for horses and buggies and later for cars. As the tunnel predated the motor vehicle era, it was too narrow for cars to be traveling in both directions. But once US 52 was built in the area, OH 93 was realigned to go around the tunnel instead of through the tunnel, so the tunnel was closed to traffic in 1960. The legend of the haunted tunnel states that since there were so many accidents that took place inside the tunnel's narrow walls, the tunnel was cursed. The haunted legend states that there was an accident between a tanker truck and a school bus coming home after a high school football game on a cold, foggy Halloween night in 1
