Interstate 805

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.

As ridership and routes increase - the engine of North Carolina passenger rail trains will become a more common sight.

US Route 101 in Benbow, Garberville and Redway

The communities of Benbow, Garberville and Redway can all be found along US Route 101 within southern Humboldt County.  The former surface alignment of US Route 101 in Garberville and Redway once crossed the Garberville Bluffs along what is now Redwood Drive via a corridor constructed as part of the Redwood Highway during the 1910s.  US Route 101 through Benbow, Garberville and Redway was modernized by 1935.  US Route 101 would eventually be upgraded to freeway standards in Benbow, Garberville and Redway by extension of the Redwood Freeway during 1966-68.  As the cover photo the original grade of US Route 101 and the Redwood Highway can be seen at the Garberville Bluffs during 1934.  US Route 101 can be seen in the communities of Benbow, Garberville and Redway on the 1935 Division of Highways Map of Humboldt County .   The history of US Route 101 in Benbow, Garberville and Redway Benbow, Garberville and Redway lie on the banks of the South Fork Eel River of southern Humboldt County.  D
