It's not really comparable. I-395 runs through only 3 or 4 blocks of waterfront, I-95 in Boston was quite different. Besides there is already the elevated Metromover next to it (which is an elevated structure through much of downtown Miami).

Exactly it has little impact on the waterfront and you're right its much different than Boston and not worth it to put the highway underground.

From my own experiences driving though the area, that could very well have been a Sunday afternoon.

That's why they are currently constructing that three-lane reversible HOT facility in the median down to Stafford.

The choke point has always been well south of where the current HOV lanes end, though. Usually Fredericksburg.

There are plans to expand that section down to Richmond as well, by tolling the existing Interstate.

I think the bigger point is this: as long as that's only one of two north-south routes through that part of the state (the arterial, very suburban US 1 is the other), I-95 will continue to be congested. And as Northern Virginia suburbia/exurbia extends further south, so will the congestion.

I was going to say, whenever I'm in the Washington area on weekends, 95 in Virginia - as far down as Fredericksburg - is mentioned in the traffic reports.

There has been substantial population growth in the Fredericksburg area in the last 20 years. For example Spotsylvania County grew from 57,000 to 122,000 people between 1990 and 2010. Stafford County also doubled during that period, from 61,000 to 129,000 inhabitants. Add the city of Fredericksburg to it and you have an urban area with around 300,000 people. However, most employment is either in the Washington or Richmond areas. So people commute. Those are California-style commutes.

I-15 Project Neon, Las Vegas, Nevada

Check out this huge $ 1.8 billion / 3.7 mile mega project along I-15 in downtown Las Vegas. It's currently a 2x5 freeway.

I wonder if this will get build, I heard about this project long time ago.
I know they are building the express lanes on I15 from I215 to like Tropicana.

I hope they build this

Those would be at the northbound split between the two so-called "spurs"; you'd also see them at the split between the cars-only and cars-trucks-buses lanes, at the southbound split between the spurs....

I don't know how easy it is to tell from that photo what's going on, but the signs have panels in them; that's the default position. If one side is congested, or actually closed, they can change the panels to direct everyone the "good" way. In that situation, the background color on the warning panels is red.

Are the neon ones* the first VMSes in the world?

*The AARoads thread says they go back to the opening of the Turnpike in the '50s; what I've called the splits haven't existed that long - the "Western Spur" opened about 1970 - so I'm assuming the changeable-panel signs go back onlly that far.


EDIT/PS: note the beehive state highway markers in your Utah post.
Quoting myself because I just happened on this:

http://ops.fhwa.dot.gov/freewaymgmt/.../exhibit15.jpg

Judging from the angle of the left-hand ramp, this would be on the way out of a service area (or maybe entering at an interchange), not at the main split.

I-15, Utah

The massive widening project of Interstate 15 in Utah County, Utah was completed significantly under budget. The 24-mile section was widened with an additional 2 lanes in each direction, to as much as 2x6 lanes. The project had a budget of $ 1.73 billion, including land acquisition. The actual amount of money spent was $ 230 million lower than the budget.

Construction will commence next year to widen an additional segment south of Spanish Fork to 2x3 lanes to Payson. This project is very cheap, the budget is only $ 32 million and a right-of-way is already available in the median.

I-10, Louisiana

The state of Louisiana has put plans to widen I-10 in Baton Rouge on indefinite hold. The plan was to widen I-10 from the Mississippi River to the I-10/I-12 split. This is currently a six-lane freeway. Any widening would have required significant reconstruction and right-of-way acquisition because several segments of I-10 run across viaducts with no shoulders.

They now plan to improve traffic signals in this area, although there is no decent alternate surface street that runs adjacent to I-10.

As a Californian who has now lived several years in Europe, I don't understand why the vast majority of US freeways/interstates/expressways just don't look as good as their European counterparts.

I know the US system is for the most part older; but even in places where they have expanded recently, the road quality just doesn't seem as good or as smooth as most of the Western European freeways/motorways (for example, the above photos). Add to that, the continued obsession with building traffic lights on off ramps baffles me. I know our US patriotism runs deep, but surely there are things pertaining to highway building that the US can learn from Western Europe?
