You've removed about 3 foot of white space and two lines of of text, of course the 2nd sign is smaller

If you redo the 2nd sign with the same useless white space and the "1 1/2 miles" legend, and the "To" above the shields then you end up with a sign that only a little bit smaller - i.e. the difference of the height of the arrows which is probably only about 1ft. Hardly something to get excited about.

RE: the NC 540 sign... I believe they have all that space there for future expansion when the road gets extended down to Apex and Holly Springs (and Clayton once they finally decide to put the southern part of the beltway in motion).

North Carolina's good for that... Greensboro shows much of the same with the I-73 construction.

True, but the arrow-per-lane sign at the actual split should look no different than the sign 1.5 miles out. The 3-or-4-lanes problem isn't really a problem if the roadway is only 3 lanes wide. Common sense says the middle lane has "the option". If I were to draw an advance guide sign the way they do things in California, all I would do is replace the angled up arrows with downward pointing arrows with no distance mentioned on the sign.

As someone from the area and who has driven through the Midtown Tunnel a few times, I say "it's about freakin' time."

That was a project that should have taken place the exact same time that they built the Pinners Point Interchange. Instead they waited to do it in pieces, and it further showed the need for a faster connection to that part of Norfolk.

This thread showcases info and photos on roads in the US and Raleigh was brought up because the new segment of the Triangle Expressway and 540 opened up.

Going back to the 40-540 sign I drew earlier which was actually an exit direction sign, here are the two corresponding advance guide signs. The first one is the 1 1/2 mile advance guide sign...


The second one would be placed 3/4 to 1 mile from the exit and would feature downward pointing arrows to give lane guidance...


And lastly, the exit direction sign I posted earlier...


IIRC, CalTrans usually does not include down arrows AND a distance on a single advance guide sign especially where there is a lane drop and an option lane.

Can you re-draw this sign
http://www.markyville.com/aaroads/40-540_nc-apl.png
with the same legend as this sign
http://www.markyville.com/aaroads/40...-style-adv.png
i.e remove the unnecessary white space, align the route markers and cardinal directions next to either other, and remove the distance

that way we can actually compare what the real difference in dimensions is - i.e. about a foot in height, if that

Ask and you shall receive ! I just whipped this up before I head off to work...

If you remember, the original I said was approximately 20 feet 6 inches, the sign I just drew is approximately 15 feet 6 inches... a savings of 5 feet! To me this sign is still too large because the maximum overhead guide sign height is only 10 feet in California (per CalTrans policy).

US 36 West of this bridge has controlled exits at a lot of points and looks like it was to be made into a 4-lane highway but I don't know why it never happened. I drove it one day just exploring NE Kansas and SE Nebraska. I exited at Hiawatha and headed North into Nebraska so I'm not sure how far West the setup for 4-laning goes. Google street view provides some good views of what I'm describing East of Hiawatha, KS

St. Joseph is on the Missouri River, not the Mississippi, but yes, the photo was taken during floods.

Thanks

So what size are the arrows on that sign? They must be about 7 feet high if there's a 5 feet difference between the "old" and "new" styles with the same legend?

The double arrow is 66 inches tall and the right and left arrows are 45 inches tall. I drew these arrows based on the interim spec from the Standard Highway Signs and Markings (SHSM) book.

Chisholm Trail Parkway, Texas

The construction of the 28 mile Chisholm Trail Parkway (CTP) began officially today. The toll road will connect I-30 in Forth Worth with US 67 in Cleburne and will open in mid-2014.

Approximate route:

I don't know if it's only me, but that seems like a mighty strange option for a toll road. I might understand the I-30 to I-20 connector, people might pay for that, but what's the use of extending it all the way to Cleburne?
