An I-540 Preview

With the next segment of I-540 about a month away from opening to traffic, I took a small ride out to Western Wake County and took a look at the highway before it opens.

Note: The official exit number is within the parentheses. An error in signing plans caused the exit numbers to be 20 miles off.

Exit 47 (67): NC 55
This exit will be a six ramp partial cloverleaf interchange. This will be the current end of I-540.

Approaching I-540 from NC 55 West in Morrisville.

This time I am on NC 55 East at the interchange. I-540 will include the 'Future' designation. This is because of a rule that says Interstates must end at a National Highway System (NHS) route. NC 55 obviously is not a part of the NHS.

Exit 49 (69): Davis Drive/Research Triangle Park

This exit is an expansive Y-shaped interchange linking I-540 to the heart of Research Triangle Park. The interchange flows into Kit Creek Drive which provides quick access to Davis Drive.

Kit Creek Drive ends as the ramps to/from I-540 begin/end.

A wide view of the expansive I-540/Davis Drive Interchange.

Folks leaving RTP to get on I-540 will come to this split on the on ramp. What's interesting is that the 'Future' tab is missing here.

A full 22x zoom looks over a mile north/east on I-540 towards NC 54 and I-40. I didn't have my tripod with me or the Future East 540 shield that sits behind the 1/2 mile guide sign for NC 54 would be clearer.

Exit 50 (70): NC 54

The last of the three new exits for I-540 will be for NC 54 just on the Northeastern edge of RTP. Unlike the interchange at NC 55, signs aren't up for I-540 nor is the highway opened to four lanes.

Heading east on NC 54 approaching the I-540 interchange. The new travel lanes on the right aren't quite ready for NC 54 East to move onto them. The interchange with I-540 will be a partial cloverleaf known as a folded diamond.

Closed off and unpaved ramps to/from I-540 East at NC 54.

Nice pics! Any sign that they have started land purchase for the next part of the western leg?

There hasn't been any, yet. Once and if the NCTA gets funding from the General Assembly, the land purchases on the Western Wake Expressway will begin.

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n

Former US Route 50 and the South Lincoln Highway from Folsom east to Placerville

The corridor of Folsom of Sacramento County east to Placerville of El Dorado County has been a long established corridor of overland travel dating back to the California Gold Rush.  The Folsom-Placerville corridor was once part of the path of the Lake Tahoe Wagon Road which became the first California State Highway and later the South Lincoln Highway.  In time the South Lincoln Highway's surface alignment was inherited by US Route 50.  The Folsom-Placerville corridor also includes the communities of; Clarksville, Shingle Springs and El Dorado. Part 1; the history of the Lake Tahoe Wagon Road, South Lincoln Highway and US Route 50 through Folsom-Placerville Folsom is located on the American River/Lake Natoma of eastern Sacramento County.  That lands now occupied by the City of Folsom were part of Rancho Rio de los Americanos prior to the finding of gold at Sutter's Mill during 1848.  During the California Gold Rush the lands of Rancho Rio de los Americanos were purchased by Jose

Legacy of US Route 466 Part 3; Morro Bay to Shandon via Rocky Canyon

Part 3 of the US Route 466 Legacy series consists of the roadways that made up the highway between Morro Bay and Shandon of San Luis Obispo County.  The San Luis Obispo County segment of US Route 466 is notable due to it having been carried via a dirt segment through Rocky Canyon from 1933 to 1958.  Pictured in the cover photo of this blog is former US Route 466 facing westward into Rocky Canyon. Part 1 and Part 2 of the US Route 466 Legacy Series can be found below: Legacy of US Route 466 Part 1; California State Route 46 Legacy of US Route 466 Part 2; Tehachapi to Bakersfield  Part 1; mapping early US Route 466 in San Luis Obispo County As discussed in Part 1 of the US Route 466 Legacy series the western terminus of US Route 466 ("US 466") from it's inception until truncation in the 1965 was located in Morro Bay at California State Route 1 ("CA 1"). US 466 between Morro Bay and Shandon had two two primary alignments through it's history.  The initia
