I believe there are some who would like to rebuild this entire section somewhat to the east, (reclaiming the river waterfront) and mostly underground, but with today's budgets won't happen anytime soon.

Is that I-95 at Pocahontas Parkway near Richmond? It's "odd" because the bridge carrying Pocahontas Pkwy over the James River needs to have an usually high clearance for an inland bridge because the river is navigable to ocean-going vessels all the way to Richmond!

Yep, I've seen videos of that interchange, it's huge. The fly-overs must be one of the tallest in the country.

I hear they are building a third highway loop around Houston. It's a State Highway 99 or Grand Parkway.

More info and detailed map here: http://www.grandpky.com/segments/default.asp



They are also expanding Highway 290.



http://abclocal.go.com/ktrk/story?se...cal&id=7647763
http://www.my290.com

Quote:
The overall vision for the US 290 Program includes:

* Freeway capacity reconstruction and widening from IH 610 to FM 2920 to create:
o Five general-purpose lanes in each direction from IH 610 to just west of SH 6, plus auxiliary lanes where appropriate
o Four general-purpose lanes in each direction from just west of SH 6 to near the proposed SH 99/Grand Parkway, plus auxiliary lanes
o Three general-purpose lanes in each direction from near the proposed SH 99/Grand Parkway to the west study limit, plus auxiliary lanes
o Two- or three-lane frontage roads in each direction throughout the corridor

ALSO:

* A four-lane, two-way managed lanes facility along Hempstead Tollway from IH 610 to the proposed SH 99/Grand Parkway
* Two non-tolled frontage road lanes in each direction to be reconstructed along Hempstead Tollway from IH 610 to Beltway 8
* US 290 METRO HOV operations moved to the Hempstead Tollway managed toll lanes
* Proposed high-capacity transit corridor located along Hempstead Tollway
* Bicycle and pedestrian improvements
Proposed expansion: http://www.youtube.com/watch?v=ggzmQo_qa0U
Beltway 8: http://www.youtube.com/watch?v=5-wmD_Sk0-E

Any other Houston roads planned for expansion?

I wonder what it's like to live in such a sprawled-out city as Houston. Is it even possible to get from any point to another in less than an hour?

Houston was actually the only city to reduce congestion between 1990 and 2005 or so. But you're right, the city is huge, but then again, the population is almost 6 million, which would be a world city with that size. The only thing different from east coast cities is that there are no dense residential areas at all. Everything are detached homes, because the city developed much later than east coast cities. Houston had only 300,000 inhabitants in 1930.

Houston, with its two (soon to be three) beltways, is actually less sprawled than Atlanta. Beltway 8 is only a few miles farther from downtown Houston than I-285 is from downtown Atlanta. Houston is big, but you can get from one end to the other in about an hour during most times of the day outside rush hour.

One does have to remember that (at least within the city limits of the City of Houston), there is no municipal zoning law, so residential developers have a fairly wide latitude on how densely they can build their developments whereas in the Atlanta area, the city and its suburban areas are heavily zoned and those jurisdictions have very low legal unit density limits.

Thus, to me, it is no surprise that metro Houston is more dense and less 'sprawled out' than metro Atlanta.

I wonder if this third beltway, if actually completed, will be built to Interstate standard. The name "Grand Parkway" is obvious, but I think with growth in the area, it can't simply be a narrow highway. Plus, would be nice to see a new Interstate designation.

Also, I read once that the Beltway 8 tollway is not even completed on the Northeast side of the city, it's just frontage roads.

Probably not fully interstate standard, but it will be limited access like Beltway 8 eventually. The Grand Parkway is being built with future limited-access upgrades in mind: meaning there are no access rights to the road itself to private businesses or small residential side streets, sufficient right of way exists from the beginning, and all intersections that are signalized are a certain distance apart and built with future overpasses in mind. Take a look at the southern half of the existing section of the road in Ft Bend County and you'll see what I mean.

That Northeast section of Beltway 8 is being upgraded to limited access as we speak. The new limited-access toll lanes (which will basically be the Sam Houston Tollway NE section) are under construction now. I think it's supposed to be complete next year.

The term "longest planned beltway in the world" is quite dubious.

Some projects I know (motorway/freeway status);

* Центральная кольцевая автомобильная дорога (CKAD) - Moscow: 522 km
* State Route 840 - Nashville: 287 km
* Grand Parkway - Houston: 274 km

The current longest full beltway is the A10 around Berlin, Germany, which is 196 km long. The M25 around London is slightly shorter at 188 km.

one more:
* Big Beltway of Warsaw (DK50/62, planned upgrade to freeway): about 300 km

Topic for beltways:
http://www.skyscrapercity.com/showthread.php?t=744080

This is for US I-states, like I-99 and I-238.
PS: Once, I drawn a 2nd beltway for Washington DC and called it I-666 .

So weird. And a waste of sign space.

^Really? You don't like them?

I think the new arrows do a much nicer job of explaining how a "decision lane" is going to split then the current signage.

I'll admit the ramp signage seems like overkill.

They're clearer indeed, but I prefer the German style-arrows. They just look better and require less space.
