However, as part of the discussion on the AARoads Forum, I did create this sign drawing based on another member's suggestion that has some resemblance to your suggestion...



The only problem with this style is if the control city for CA-57 is "Sacramento" or "Philadelphia", it wouldn't fit on the sign.

I could use an up arrow sign. One thing I don't like and I try to avoid is the "Only" yellow box which looks akward. When the sign points accurately at every lane.
And BTW, for the part you said there are two arrows pointing at one lane, that depends on perspective. Like this picture:

That diagram appears to be from the 2003 MUTCD. The MUTCD was revised in 2009 and that diagram has been removed.

Looks like Maryland, minus the wretched Clearview. Highway Gothic 4 Lyfe.

I-5 Santa Ana Freeway, Norwalk, California

http://www.nbclosangeles.com/news/lo...190102061.html

Construction begins on a one mile segment of I-5 in Norwalk (southeast of Los Angeles) to widen the freeway from six to ten lanes. It's a part of the multi-phase widening of I-5 between CA-91 and I-710 to 10 lanes. This is one of the worst bottlenecks in California, nearly all other freeways in the region have 10 lanes, but a 6-lane bottleneck remained for a long time near the county line.

"Sacto" and "Phila." (I've actually seen "Phila" on BGSs. No clue about "Sacto" though.)

Lets not go there about the metric thing, unless you want 5-6 pages of utterly pointless flame war.

Yes, that was quite a slight in the way it was phrased.

And yes, the metric/miles discussion isn't that fruitful.

Now that we have established that having the metrication debate again is a complete waste of time and bytes...
Here is the new Zoo Interchange (I-94/I-894/US 45/Future I-41) in Milwaukee, WI set to start construction this spring:

I agree, Interstate 4 through Orlando is in need of a desperate makeover despite so many widenings that have taken place over the years.

First, the Kirkman Road exit that ties in with Universal Studios Orlando. Those left lane exits are a hazard, especially when you are coming to Universal from the Tampa/St. Petersburg area and - all of a sudden - you have to be in the left lane if the variable message signs tell you to use Kirkman Road. Moreover, if you are not headed to Universal but you are staying in lodging that is immediately adjacent to Interstate 4 and Kirkman Road and if you are coming from the west, if your lodging is on the right hand (east) side of Kirkman coming off of eastbound Interstate 4 you have to do a quick yet dangerous merge to the right. I know this because I stayed on a few occasions at a hotel in this immediate area.

Second, the interchange with FL Toll 408 at Interstate 4 in downtown Orlando. The double trumpet interchange that connects FL Toll 408 with Interstate 4 was built in the early 1970's and is functionally obsolete. The ramp movements that I have seen in the renderings when constructed will make transitioning from FL Toll 408 (also known as the East-West Expressway) to Interstate 4 and vice versa much smoother and without having to change lanes as you have to do now on the trumpet interchange.

Overall, the improvements will bring a lot of relief to Orlando area motorists who use these roads daily, especially during the morning and evening commutes. Moreover, the Florida DOT is timing the improvements right: Construction is set to begin in 2014, right about the same time that the first segment of SunRail (Orlando's commuter rail system) is opened. I apologize for being slightly off topic; wouldn't the Florida DOT highly encourage commuters to consider using SunRail while the reconstruction of Interstate 4 takes place? It's been done before in Florida: Tri-Rail (South Florida's commuter rail system) was originally supposed to be a temporary commuter rail service while reconstruction of Interstate 95 was taking place; right after all was said and done on Interstate 95 reconstruction in the Miami/Ft. Lauderdale area Tri-Rail became a permanent fixture in the South Florida commuter landscape.

re Tennessee: I-24 West Chattanooga to Monteagle, one of the most interesting aspects of that stretch is... while most states have a favored bridge type that's used throughout a project, almost all of the bridges over I-24 west of Chattanooga have slightly different designs. Nothing really crazy, just a little bit different. In 2012 I drove this stretch twice a week and took some photos I'll probably never post, but the narrative I composed in my head had much to do with how in Georgia it was easy to tell when the successive sections of the route (I-75) were built due to the uniform design features from the period during which they were built. In Tennessee, not so much. In fact, my only clue as to when I-24 was built was the dip through Georgia, where the bridge designs were clearly from 1965. OK, Georgia dates its bridges, too, but the ones carrying I-24 there have a railing design that was used only for a very brief period-- in 1964-65.

That grade west of Monteagle, near the end of the video, could really use a climbing lane in the eastbound direction. It's not unusual for truck drivers who are a little overoptimistic about how to drive that grade slow the traffic to 35 mph (50 kph) or so.

over optimistic about passing then entering the left lane? or do you mean slowing traffic to 35mph in the right lane?
we don't slow to 35 on purpose, we have the pedal to the metal(plastic) when going up hill, theres just a little bit of weight in our trailer being affected by gravity. That forces us to downshift otherwise the engine will stall from low RPM's (yes, sarcastic, condescending overtone, don't read too seriously) Yes there should be a truck climbing lane.

Now excuse me while I return to my FB games!

I can only imagine, I have to downshift into 4th when climbing that thing in my little car, sometimes 3rd if I feel like passing a vehicle doing less than 50 in the right lane.

It might not even be the fault of the truck drivers. Maybe a car suddenly decides that the right lane isn't moving fast enough and whips out in front of a truck, causing it to lose speed that it can't regain because of the grade.

Anyway, as we've all noted, a third lane would be really good to have there. Even one that ran only on the upper mile or so would be better than nothing, though that's where the current roadbed is narrowest.

At least the US doesn't suffer from the phenomenon that is "elephant racing". In the UK and rest of Europe, trucks are governed to a maximum speed of 56mph (90kph). In reality there will be trucks that will max out at speeds between 55 and 57 mph and this creates a frequent situation where trucks will try and pass each over with a speed differential of less than 1mph, but on roads where the speed limit for most vehicles is 70mph. So as you can guess these situations can each lead to long lines of traffic platooning behind trucks taking miles to pass each other and this can cause congestion on routes, not because of high traffic levels but to "elephant racing" which are effectively 55mph rolling roadblocks. This happens on 2 lane dual carriageways (4 lane divided highways) as trucks are banned from using the 3rd lane on wider highways. There have even been times that the truck that has been passed will have to re-overtake the truck that took more then ten minutes to pass it because it has a heavy load and the next inclines has robbed it of mementum. So the frustration begins all over again. Quite often, because all traffic ends up queueing in the outside lane behind the passing truck, other trucks will undertake in the clear inside lane then barge in (their method usually involves indication, and crating a gap to force themselves into), so again more elephant racing and more frustration as others struggle to get past to a clear road ahead.

The solution to that problem is banning trucks from overtaking on flattish sectors on busy 2x2 highways, confining them to the right lane.
