Interstate 805

By
Recently while visiting the San Diego Area I drove a portion of Interstate 805 in northern San Diego to California State Route 163.


I-805 is a 28 mile spur route of I-5 which begins in northern San Diego and ends near the Mexican Border in the southern extent of the City in San Ysidro.  I-805 was approved as a chargeable Interstate in 1958 and was added to State Highway System as Legislative Route Number 241 in 1959 according to CAhighways.org.

The planned route of I-805 on LRN 241 first appears on the 1960 State Highway City Insert.

According to CAhighways.org construction of I-805 began in 1966 and was completed by 1975.  The 1970 State Highway Map City Insert shows I-805 under construction between CA 274 south to CA 15 (future CA 15) and in Chula Vista.

I-805 is shown as fully completed on the 1975 State Highway Map City Insert.

My approach to I-805 was on southbound I-5 in northern San Diego.  I-805 is known as the "Jacob Dekema Freeway" and was named after a long term Division of Highways/Caltrans engineer who served from 1938 to 1980.




Signage on I-805 south indicates I-8 is 10 miles away and the International Border on I-5 as 30 miles away.


Exit numbers on I-805 descend starting from Exit 27 at Mira Mesa Boulevard/Sorrento Valley Road.


Many freeways in San Diego including I-805 contain somewhat ornate modern bridge designs such as the Eastgate Mall overpass.



Exit 25B on I-805 south accesses Miramar Road and La Jolla Village Drive.


Exit 24 on I-805 south accesses Governor Road.


The first major junction on I-805 south is at Exit 23 which accesses CA 52/San Clemente Canyon Freeway.




Exit 22 on I-805 south accesses Clairemont Mesa Boulevard.


At Exit 21 I-805 south accesses Balboa Avenue which is former CA 274.  All of CA 274 was deleted in 1999 and relinquished by 2001.


At Exit 20 I-805 meets former US 395 on CA 163/Cabrillo Freeway.  I turned south on CA 163 and headed towards downtown San Diego.

2018 Mojave Road Trip Part 2; The deadly desert highway (California State Route 127 and Nevada State Route 373)

By
After leaving Barstow via Old Highway 58 my next destination was in Death Valley.  To access Death Valley from rural San Bernardino County required a trek on north on Interstate 15 to California State Route 127 which becomes Nevada State Route 373 at the state line. Along I-15 I encountered the road sign oddity that is Zzyzx Road about eight miles south of Baker.   Zzyzx Road is a four mile road that used to go to the Zzyzx Mineral Springs and Health Spa.   The spa was founded in the 1940s and the owner made up the name "Zzyzx" to claim it was the last word in the English Language.  The spa has been shut down since the 1970s and is now part of a Desert Studies Center for California State University. The southern terminus of CA 127 in Baker is located at I-15 exit 246.  CA 127 is a 91 mile north/south highway which runs to the Nevada State Line in Inyo County.  CA 127 is called Death Valley Road from I-15 northward.  South of CA 127 ...

Finding the Pre-Emption Road of New York State

By
  The Pre-Emption Road (or rather a series of roads named Pre-Emption Road) follows a survey line called the Pre-Emption Line, drawn in the early days of the United States. The story begins with Massachusetts and New York having competing land claims to modern day Western New York State that have their roots in colonial charters granted by the British. After the Revolutionary War ended, this land became the frontier of the nation and its settlement became a priority for the new American government. During this era, there were a lot of competing land claims that needed to be settled. It was no different with the land claims between New York State and Massachusetts. On November 30, 1786, Massachusetts and New York sent representatives to Hartford, Connecticut to resolve their competing land claims. In less than three weeks, the representatives had reached a compromise. Massachusetts would receive pre-emption rights, meaning the right to sell the land after the Indian title ...

What's In a Name?: When the Roads Really Do Tell a Story

By
  Our tagline on the Gribblenation blog is "because every road tells a story". Some roads tell different stories than others. Along our travels, we may see historic markers that tell us a little story about the roads we travel or the places we pass by. Some historic markers are more general, as to telling us who lived where or what old trail traversed between two towns. During my travels across New York State and other states or provinces, I pass by many historic markers, some with interesting or amusing references to roads. I wanted to highlight a few of the markers I've seen along my travels around the Empire State and help tell their stories. Those stories may be as specific as explaining the tales of a tree that was used to help measure a distance of eight miles from Bath to Avoca in Steuben County, as referenced on the Eight Mile Tree historical marker above. They may also help point the way along historical roads first used centuries ago, or may help tell a local l...
