Here's a photo of it's construction from the Birmingham News



Do you have any further information?
Construction on the interchange started in 2011, I think they are currently on schedule, but I think they havent started on the extension to US 31 though.

There was a discussion between MSDOT and ALDOT on discontinuing US 78 west of Birmingham. I think the plan is when I-22 is completed, US 78 will remain on its original routing in Alabama.

As it should. I think it's a disservice when US routes are decommissioned when Interstates are built over/alongside them. They're the easiest alternate routes to follow in case of congestion, IMO.

The congestion was awful. You can see just how heavy the traffic is from the rest stop. The road is 2 x 2 through this portion.

I think widening I-15 Victorville - North Las Vegas should be fairly cheap (1 extra lane per direction).

I guess they will be HOT lanes (so also non-2+ users can use them when they pay) so they can get the money back. And the traffic that will take the new lanes won't be taking the older lanes so they will be relieved from traffic.

Yeah, the new lanes they are building on I-635, will be HOT lanes which will be free for carpools, but solo drivers will have to pay a toll which is based on traffic levels/time of day.

I-10 / Loop 375, El Paso, Texas

Another cloverleaf is eliminated in Texas, replaced by a large stack interchange.

It's the I-10 / Loop 375 interchange in eastern El Paso. The first phase opened today. The second phase includes the other direct connectors.

I don't for obvious reasons... MUTCD violations, white guide signs, metric, improper typefaces, etc. Was this mockup meant to replace standard variable message signs (VMS) or supposed to be an exit direction signs with a small VMS integrated into it? Why are the control cities white-on-black? This kind of thing might work in Europe but not here.

I believe I-15 between Victorville and Barstow is already 6 lanes (3 each way). The only 4-lane section of I-15 is between Barstow and the California-Nevada stateline and I do wish Caltrans would get their rear-in-gear and widen that section of freeway.

What's wrong with metrification? If Canada could do it why not the USA? Now the US is the last important country which does not follow metric units.

Here's my drawing of signs in the previously posted photo that eliminates all of the European elements and brings it, more or less, in line with the current MUTCD although this might be a case where the new arrow-per-lane sign would be used...


Note: Just looked at the original drawing and there's an error in my drawing. Accident isn't 4 miles ahead, the backup is 4 miles long before SR-520. Oh well...

I'm not going to bother with this because all it results in is a flame war. All I will say is the U.S. is not going metric anytime soon.

What are the chances of US doing some serious improvement of I-40 through the Appalachians? It is a very twisty road, with tight curves. They could build some new alignment with more tunnels and high viaducts.

Actually, it is quite impressive US has so few non-urban highway tunnels.

I actually prefer the European forward signs. The American down signs are retarded.

Yeah that is kinda sad that they don't wanna follow the metric system.
And for the signs they don't have to be europeanized. They can follow something simillar to the new South Korean System:




Or the Ontarian system
