St. Croix Crossing

Another photo of the St. Croix Crossing near Stillwater, Minnesota. It is an extradosed bridge, a new bridge type, only a few of these bridges have been built in the U.S.

Yes, finally a more unique, modern desgined bridge in the Midwest, more specifically Wisconsin, other than the tied-arch bridge in Superior, Green Bay and Milwaukee, or the I-41 causeway like in Oshkosh. But if one were to ask me my opinion on this particular one, a 4-lane bridge might be overkill.

Bayonne Bridge

Bayonne Bridge's new elevated roadway set to open

A new era for the Bayonne Bridge will begin Monday when the newly constructed elevated roadway on the 85-year-old arch bridge opens to drivers.

The new roadway, which was built 64 feet above the original bridge deck, hangs 215 feet above the Kill van Kull. The work is part of the Port Authority's massive "Raise the Roadway" project, which will allow larger container vessels to pass under the bridge and reach local ports.

"On February 20, we will make history,'' Steven Plate, the Port Authority's chief of major capital projects, said in a statement. "The Bayonne Bridge, a marvel of 20th century engineering, will become a groundbreaking innovation of the 21st century.''
Full report: http://www.nj.com/hudson/index.ssf/2...t_to_open.html

This is a very unique project as well. I cannot recall any similar project where they built the deck higher up in the span of an arch bridge. Though some bridges have been double-decked at a later point (the George Washington Bridge and Verrazano Narrows Bridge being prominent examples).

After an human error and serious mishap earlier on the project, SR-99 in Seattle is advancing fast. Bertha, the TBM excavating "the largest-diameter road tunnel in the World" as they claim, is about to break through the northern portal



The project is almost 2 years behind schedule, as a contractor left a hard-steel probe pipe very close to the southern portal, did not document it properly, and then the TBM got stuck/damaged when it hit the steel pipe.

It will be a double-deck tunnel, 2 regular lanes per direction and a full "should running" lane which I expect to be operated effectively as a third lane.

Some pics of the interior

That tunnel is the largest waste of money on a road project in Washington state history. The new tunnel will have reduced capacity, no exits to downtown, and has poor access to downtown where it exits on the north end. When considering they will add a toll this will make what is already one of the worst bottlenecks in the country on I-5 even worse since it will force cars onto I-5. It will be nice to have the ugly viaduct off the Seattle waterfront but they dropped the ball on this project. It's a cool engineering project nonetheless, but it won't do anything to improve Seattle's traffic issues.

California State Route 1

A bridge across Pfeiffer Canyon in the Big Sur has cracked significantly after floodwaters eroded away the support columns on February 15. The bridge is damaged beyond repair and must be replaced. CA-1 is the only road in this area, traffic needs to take a huge detour, so tourists can't drive the full length of the Pacific Coast Highway in the Big Sur.

1960s-1980s, from the looks of it.

A map showing the closure on Big Sur Pacific Highway:

I hope they will fix this issus soon. I have been lucky enough to be able to drive this entire highway last autumn. It's one of the best drives I have ever made.

So what would you have proposed? It is easier to complain about a problem than find a viable solution. The Seattle area is expected to add population equivalent to another Seattle in 20 years. More surface roads can not be built due to space and congested corridors, land and construction costs are rapidly rising in Seattle, earthquake damaged Alaskan Way Viaduct would cost billions to repair and is an eyesore as you have stated previously....yes, it's easy to complain but eventually you need to make difficult choices. Four million people depend on reasonable choices based on reality.

Oh yeah, uh-huh. Oh yeah, uh-huh.

It's my brother's birthday (yesterday). It's my brother's birthday (yesterday).

Note that it was inspected two years ago and found to be in perfectly satisfactory condition. So much for "neglected infrastructure". It just goes to show that more is probably needed even WITHOUT mother nature exceeding expectations.

Honestly, the connections on both ends of Route 99 are so poor already that I don't think many are going to be motivated to go on I-5 because of the toll. But yes, this project won't fix Seattle's traffic issues, it is a vanity project to open up the waterfront which currently is so ugly due to the viaduct.

The simultaneous closures of CA-1 Big Sur have completely cut off some small communities, which have no other road access. The second bridge closure also involves large slope movements /landslides. They will build a temporary bridge meant only for pedestrians and maybe light golf carts.

If I see correctly, the road section closer to the photographer, has 1 lane in each direction, plus hard shoulder on both sides. Why would they do that?

In other countries a road so wide would be marked as a 2+2 or even a 3+3 expressway (without such high safety standard, but still)...
