Another bridge shut down indefinitely due to structural deficiencies. If this gets severe, we could wind up having to spend a fortune on a replacement, in an era where we have to spend billions of dollars just to get our infrastructure in tiptop shape.

I don't know if this is a structural deficiency, or an extraordinary event. The bridge opened to traffic in 1981, most deficient structures are 15+ years older.

Some are guessing it has to do with how the foundations where laid 30 years ago. The superstructure itself is of a redundant design and except for some minor, normal wear and tear related surface cracks on a pier or two the bridge passed its last round of inspections with flying color.

Here is an interesting post by user "triplemultiplex" over on AARoads about the geology of the area:
Quote:
The bridge spans the mouth of the Fox River; it's an area that's a filled-in estuary. The industrial area under the bridge originally looked like the marshy area around the 41-43 interchange. Locally, it's going to be one of the deepest areas to bedrock. There is also going to be significant clay layers as the lower Fox River was the location of a significant pro-glacial lake until the Green Bay lobe retreated north of Door County. (Outlets for that lake formed the initial valleys for the Kewaunee and Ahnapee Rivers further east, incidentally.)

Get east and west of where this bridge is and bedrock would be quite shallow. The Niagara Escarpment is the most significant geological feature in eastern Wisconsin, for example...

Yes, the structure itself is ok, its either the foundation under the pier or the earth under the foundation that failed or settled more, so far.

Bedrock is estimated to be 140 feet below the surface. When the bridge was built, the metal pilings in the pier and into the ground were driven 100feet, and were "assumed" to have hit bedrock. This was mentioned on local GB, WI news Thursday night. The word assumed was used.

Having lived now in CA, I would say that the roads here are more impressive in photographs and videos (as well as to visitors) than they are in person, or at least persons having to depend on them. The best thing about them is probably the views of the nearby scenery. The road surfaces are busted, probably the worst of any sunbelt state, and comparable to many Northern states with freeze-thaw cycles. There's also a sense that a lot of capacity has been squeezed in that perhaps shouldn't be there. For example, in many places there are minimal shoulders. The entry ramps are also tiny, compared to what I'm used to in the suburban Midwest.

There's also garbage all over the sides of the road here, which you don't see in those videos. Even the nice parts of LA have crap all over the sides of the road.

Finally, in the cities the major expressways seem permanently congested at all hours.

Arizona, overall, probably had the best interstates, IMO. The expressways in Phoenix (as well as elsewhere in the state) were immaculate. I loved the spacious, well thought out design and they were a joy to drive.

I thought Arizona had nice highways too in the warm areas. Not as much in the higher elevations of Flagstaff though. Those highways are so lightly travelled and have little weather variation in most of AZ.

The new I-90 Dresbach Bridge project over the Mississippi River between MN & WI near La Crosse, Wisconsin; is well under way. The current bridge is being replaced due to it having a non-redundant design and not meeting modern geometric standards.

Looking towards MN:

The project is scheduled to be completed in 2017.

I-35E, Dallas - Denton, TX

The groundbreaking ceremony of the $ 1.4 billion I-35E project was held today. The project will widen I-35E by one lane each way and also adds a two-lane reversible toll road in the median. It is built in a way that it can add another 2 toll lanes in the median for a full scenario of 4+2+2+4 lanes.

Just curious...why isn't the eastern end of the northern beltway planned to end with I-20?

A section from I-59 near Clay to I-20 near Leeds has been shown in previous plans. I dont know if this segment was dropped.

Question:

Which road system in America (USA) has the most number of vehicular lanes??

Is it the I-10 in Texas? (as many as 26 vehicular lanes)

It depends on whether you count frontage road lanes. Many Houston freeways have frontage roads that go up to 3 or 4 lanes each way. But frontage roads cannot be considered part of the actual freeway.

Nice! I wonder why they're putting the state name back into the Interstate shield, I thought the new standard was to leave the state name out of the Interstate sign.

American roadgeeks (like on AA Roads...) call that - I mean leaving the state name out - "neutering." I noticed some states (Delaware, Tennessee...) neutering their Interstate markers as far back as the 80s. I believe neutering is the recommended standard but lots of states ignore that. I like non-neutered Interstate markers. (Just in my own travels in recent years*: Connecticut and West Virginia seem very consistent non-neuterers, Maine (slightly) and New Jersey less so... you'll have to search long and hard to find a non-neutered marker in Illinois, Ohio, New York....)

*Thanks to my last road trip, since becoming a car-owner again in 2009 (after years living in a downtown high-rise and only driving when I borrowed or rented one) I've driven in every state from Virginia and Kentucky north and from Illinois and Wisconsin east except Vermont. Plus Quebec and Ontario. This is just to say that I'm unfamiliar with the current state of the roads farther south and west.
