Since the latest news have mentioned that the Pacific Highway in California has been closed down for a longer time due to a bridge beeing damaged, I have decided to post my own pictures from that I shot back in October last year while driving from Los Angeles to San Francisco on that coastal road.

First highway 101 between Los Angeles, going through Santa Barbara and Santa Maria:









At San Luis Obispo I left highway 101 and started driving on CA-1:

On the side of the road:



Continuing on CA-1:



The beautiful coastal road starts where the mountains rise directly from the ocean:

This is not Bixby bridge, but still good looking:





Spectacular scenery:

Finally I have reached Bixby Creek Bridge:



The clouds were very low and moving fast, but I managed to take some decent shots of the bridge in the few seconds when they were not covering the bridge.



Unfortunately I don't have more pictures from Big Sur area north of Bixby bridge as my car broke down immediately after I left Bixby bridge...

This photo was taken from the SH 130 interchange, evidently the mainline lanes split to SH 130 and SH 71. It seems unusual to have only two through lanes on SH 71, considering it is one of two highways between Austin and Houston. The frontage roads have higher capacity than the mainline, which is unusual.

It doesn't seem to have been built with a future freeway to the east in mind.

There's not enough traffic to justify more. Which just shows how insane this project was to begin with.

That is incorrect.

The 2015 AADT on the presently built stretch of toll road was between 57,000 and 98,000 vehicles. East of SH 130, it carries 51,000 vehicles per day.

Even with 51k AADT, it could be that most of that turns so there's not really enough through the junction to justify more than one lane.

Why not mark two or three lanes anyway? One possibility is to save on construction and/or maintenance costs. Shoulders are often built to a lower level of strength and durability than running lanes, and are not resurfaced with the same regularity.

Another possibility is to facilitate the merge/diverge where there's a high proportion of turning traffic. Here the M3 outside London, UK is marked down to one (rather wide!) running lane westbound, though the carriageway is wide enough for three lanes plus hard shoulder. This is because there are very high turning volumes from the M25, and a more orderly merge can be achieved with a double lane gain. Maybe something similar is happening at SH 71/SH 130.

Until now through traffic used the frontage roads (which are two lanes in each direction). Combined, there is sufficient capacity through the 71 / 130 interchange, but it seems weird not to build a standard four lane divided through there, because that's exactly what they did at US 290 (Manor) and US 79 (Hutto).

Well again there are no exits to downtown which the current viaduct has. The result will be even more cars using I-5 and surrounding roads instead of the tunnel. If you think a toll doesn't change driving habits look at the mess created when the 405 HOT lanes opened.

Little Rock

A new double-span arch bridge opened to traffic today in Little Rock, Arkansas. It spans the Arkansas River and replaces an older bridge. It is part of Broadway Street / US 67.

One of my wishes is to drive down 101 down the coast to California. Great photos!

More traffic on surrounding roads, but I don't know about I-5. The viaduct is a poor bypass of it, due to it's lights on both ends. Seattle's traffic situation is already messed up, I don't think the tunnel would make things much worse.

The tunnel was probably the best long term solution for the aging viaduct. It could have been done cheaper though.

Hwy 1 is one of the best drives ever. I always wanted to drive Hwy 1 from SF to LA but once I had a few days off I decided to go camp at Death Valley but I choose the long route..I drove Hwy 1 from San Francisco to San Luis Obispo and from there to Death Valley..12 hrs of pure awesomeness! I sacrificed few hours of camping at my destination but at the end was worth it. I would do it all over againg with no regrets

I've found quite a strange interchange design, which could be called a 'Kentucky cloverleaf':

https://www.google.co.uk/maps/@36.99.../data=!3m1!1e3
https://www.google.co.uk/maps/@36.89.../data=!3m1!1e3
https://www.google.co.uk/maps/@37.87.../data=!3m1!1e3

I can only think that these were full cloverleafs that have been reduced to four ramp interchanges in bizarre fashion, leaving weaving on the freeway mainline, though why Kentucky would choose to do that, I cannot say.

This hypothesis seems to be supported by the land around the second and third examples. Whatever the case, these interchanges have been as they currently are since at least the 90s according to Google Earth historical imagery.

The reason they exist is to have just one toll-plaza serving all the ramps, and the mainline too. They were built like that and the only thing that has been changed is the toll booths are now gone.

That makes sense. So is the appearance of a cloverleaf-like shape in the land around the second and third examples an illusion? Or were they originally cloverleafs, then reduced in this fashion to accommodate the toll booths?

I don't think they used to be full cloverleafs, it was built this way so that all movements would pass through the tollbooth underneath the overpass:

Interesting. So is this just a Kentucky thing?

Kentucky built many tolled parkways back in the day. I guess it's possible for other states to have (had) similar toll booths.
