US 101, Golden Gate Bridge, San Francisco, CA

A new movable barrier system is being installed at the Golden Gate Bridge this weekend. It will separate directions (hence reduce head-on collisions) and provide more peak hour capacity (4 lanes instead of 3).

Haven't they had reversible lanes (peak 4-2) for decades on the Golden Gate already? As far as I know that was the case the last time I drove across in the late 90's.
The movable barrier is a great improvement though.

I think they had movable tube pylons in the pavement. It was quite a job to move them manually all the time.

Too bad they couldn't have painted them red like the bridge or something. Looks ugly.

Like the unelected little old lady on your coinage?

You do realize that's George Washington, right?

That zipper is so beautiful and clean. So is that moveable barrier. Everytime I look at the one on I-30 in Dallas I cringe. Such bad condition and crumbling and the zipper trucks look like they've been in accidents with cars.

US 460, Virginia

VDOT, FHWA AND U.S. ARMY CORPS OF ENGINEERS MAKE PROGRESS ON ENVIRONMENTAL WORK TO IMPROVE U.S. 460 CORRIDOR IN SOUTHEASTERN VIRGINIA

Recommended Preferred Alternative identified

The Virginia Department of Transportation (VDOT), the Federal Highway Administration (FHWA) and the U.S. Army Corps of Engineers have identified an alternative that appears to be the Least Environmentally Damaging Practicable Alternative to improve the U.S. 460 corridor in southeastern Virginia.

The recommended Preferred Alternative would improve 17 miles of U.S. 460 from Suffolk to west of Zuni. A new four-lane divided highway would be built from the U.S. 460/58 interchange in Suffolk to west of Windsor. From west of Windsor to west of Zuni, the existing U.S. 460 would be upgraded to a four-lane divided highway and include a new bridge across the Blackwater River to eliminate long standing flooding problems.


full press release: http://www.virginiadot.org/newsroom/..._u.s.78870.asp

It was originally planned to construct a toll road all the way from Petersburg to Suffolk, but that plan was scrapped last year. This plan only addresses a part of the original project scope. It's not clear whether this would be a toll road, or an untolled road.

The rest of the route could also be reconstructed into a divided highway. That would cost far less than a new alignment freeway, but will address the safety issues. Most of current US 460 is a four-lane undivided highway.

Illiana Expressway

The newly inaugurated governor of Illinois, Bruce Rauner, signed an executive order to freeze all discretionary state spending, in order to review them. That includes Interstate projects that have not yet commenced, including the Illiana Expressway.

Press release: http://www3.illinois.gov/PressReleas...3&RecNum=12944

The Illiana Expressway is a planned east-west toll road between I-55 in Illinois and I-65 in Indiana. It would run south of Chicago. It's a controversial project.

I'm usually in the 'pro-construction' camp, but it is unclear what problems the Illiana Expressway will resolve, and it is likely not viable as a toll road due to low usage. Similar toll projects have repeatedly shown overly optimistic traffic and revenue forecasts (a practice some experts call lying).

It runs too far south of Chicago, in an area that has seen very little growth. Although it runs through fast-growing Will County, growth in that county is not near the Illiana corridor, in fact, there has been practically no growth towards the Illiana corridor over the past 20 years.

This is a good view to show just how big of a diameter you need for a double-deck single tube tunnel. The A86 Duplex in Paris has a smaller diameter and only a 2 meter (6.5 ft) clearance.

Two different styles of state route marker. That's the sort of thing it wouldn't hurt to standardize. (I mean, have all Utah markers look the same, not switch to boring Euro-alphanumeric-color-coded-rectangles. Yuck. :-P )
