Interstate 215/former Interstate-15 East and California State Route 194

This past year I drove the entirety of Interstate 215 in San Bernardino County and Riverside County.


I-215 is a 54 mile loop of I-15 beginning near Cajon Pass in San Bernardino County and ending to the south in Murrieta of Riverside County.  I-215 essentially serves as a limited access replacement of US 66/91/395 on Legislative Route Number 31 south towards I-10.  South of I-10 the route of I-215 follows what was US 91/395 on LRN 43 to US 60/LRN 19.  I-215 shares a brief multiplex of CA 60 near Riverside and what was US 60/395 on LRN 19 to what was US 395/LRN 78 towards Murrieta.


According to CAhighways.org I-215 was first approved as a Non-Chargeable Interstate south to I-10 as I-215 in 1972.  The route designation was swapped to I-15 East by 1973 with an additional portions of Non-Chargeable roadway added south to CA 60.  By 1982 the designation of I-15 East was reverted back to I-215.

The 1975 State Highway Map shows I-15E co-signed with US 395 (I guess that kicks the whole date of truncation to Hesperia even further into the 1970s) from Cajon Pass towards Sunnymead in modern day Moreno Valley. 


Of note, the map above shows the unsigned CA 194 aligned over all of what would become I-15E.  The designation of CA 194 (which was the second time this number was designated) was defined in 1974 and used as a hidden route number since suffixed highways are not allowed legislatively in California.  The hidden CA 194 designation of I-15E would disappear when the route was reverted back to I-215 in 1982.

The 1977 State Highway Map shows US 395 removed completely from I-15E/CA 194.  I-15E appears to have been completed signed on it's entire route by 1977 but clearly was using some temporary alignments south of Sun City (modern Menifee).  According to CAhighways.org I-215 wouldn't be completed to modern Interstate standards until 1996.



I-15E can be seen changed to I-215 by the 1986 State Highway Map, the 1982 Edition still shows the previous designation.  Of interest the non-Interstate standard portions of 215 south of CA 60 are shown as CA 215 on the 1986 map.

Yep, I remember when I was young it was I-15/US-395 to I-10 and then US-395 to the CA-91 interchange where it met with CA-60 and then continued south as US-395. Then it changed to I-15-E and then to I-215 for the freeway part and TEMP I-15-E and then CA-215 for the expressway part. It was confusing for this emerging road geek.

Ghost Town Tuesday; Mannfield, FL and the stairway to Hell

Back in 2015 I went searching the Lecanto Sand Hills for the original Citrus County Seat known as Mannfield.  Unlike Centrailia in Hernando County and Fivay in Pasco County I did find something worth seeing. Mannfield is located in the Lecanto Sand Hill section of Withlacoochee State Forest somewhat east of the intersection of Citrus County Route 491 and Mansfield Road. Mannfield was named after Austin Mann and founded in Hernando County in 1884 before Citrus County Split away.  In 1887 Citrus County was split from northern Hernando County while Pasco County was spun off to the south.  Mannfield was selected as the new Citrus County seat due to it being near the county geographic center.  Reportedly Mannfield had as many as 250 people when it was the County Seat.  The town included various businesses one might include at the time, even a sawmill which was common for the area.  In 1891 Citrus County voted to move it's seat to Inverness which set the s...

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...

The mystery of Hawaii Route 144 and temporary Hawaii Route 11

The 1959 Gousha Road map of Hawaii features two largely unknown references in the form of Hawaii Route 144 and Temporary Hawaii Route 11.  Both corridors are shown running from the boundary of Hawaii Volcanoes National Park east to Glenwood via Volcano Village.  At the time Hawaii Route 11 was using the so-called "Volcano Road" which was constructed as a modernization of Mamalahoa Highway during 1927-1928.  This blog will examine the two map references and will attempt to determine what they might indicate.  The mystery of Hawaii Route 144 and Temporary Hawaii Route 11 Hawaii Route 11 is part of Mamalahoa Highway (the Hawaii Belt Road) and is the longest Hawaiian State Route at 121.97 miles.  The highway begins at the mutual junction of Hawaii Route 19 and Hawaii Route 190 in Kailua-Kona.  From Kailua-Kona the routing of Hawaii Route 11 crosses the volcanic landscapes of southern side of the Big Island.  Hawaii Route 11 terminates at Hawaii Route 19/Ka...
