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.

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.

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.

Yes, the color of your nearby fire hydrant matters...

...and here's why. You will find White, Red, Yellow and Violet colored fire hydrants pretty much everywhere.  But there's a reason for this - and it's because of the National Fire Protection Association (NFPA).  This association has issued guidelines for color coding standards for fire hydrants.  These color codes from the body of the hydrant, top of the hydrant, and in some municipalities the outlet caps are designed to allow fire fighters to know what type of system, water flow rate (Gallons Per Minute or GPM), and level of water pressure.  This guideline is known as NFPA 291 and is intended to be used universally throughout the United States. The NFPA guidelines are specific to the body and the top cap of the hydrant.  If a hydrant is WHITE or YELLOW - it means that it is connected to a public/municipal water system.  If a hydrant is RED - the hydrant is connected to a private system, typically a well.  These are most common in rural or unincorporated areas

Legend of the Ridge Route; a history of crossing the mountains between the Los Angeles Basin and San Joaquin Valley from wagon trails to Interstates

Over the past two decades I've crossed the Interstate 5 corridor from Los Angeles north over the Sierra Pelona Mountains and Tehachapi Range to San Joaquin Valley what seems to be an immeasurable number of times.  While Interstate 5 from Castaic Junction to Grapevine via Tejon Pass today is known to most as "The Grapevine" it occupies a corridor which has been traversed by numerous historic highways.  The most notable of these highways is known as the "Ridge Route."  This article is dedicated to the Ridge Route and the various highways that preceded it.  This blog is part of the larger Gribblenation US Route 99 Page.  For more information pertaining to the other various segments of US Route 99 and it's three-digit child routes check out the link the below.

Establishing the numbering conventions of California's chargeable Interstates

The Federal Highway Aid Act of 1956 brought the Interstate Highway System into existence which would largely be constructed by Federal Highway Administration fund matching.  The Interstate Highway System was deliberately numbered to run opposite the established conventions of the US Route System.  While the Interstate Highway numbering conventions are now well established there was a period during the late 1950s where they were still being finalized.  This blog examines the history of the establishing of the chargeable Interstate Highway route numbers in California.  The above blog cover depicts the Interstate Highway route numbers requested by the Division of Highways in the Los Angeles area during November 1957.  The establishment of the numbering conventions of California's chargeable Interstates The Interstate Highway System was not created in a vacuum by way of the passage of the 1956 Federal Highway Aid Act.  The beginning of the Interstate Highway System can be found in the
