I agree, but in reading project concept reports for the widening of I-85 north of Atlanta, I discovered that the existing vertical alignment of I-85 is substandard, the values for K factor for vertical curves having been raised a while back. I find this especially annoying given that the section of I-85 in question is noticeably less hilly than older segments in NC and SC which have been widened as you describe.

And...

DUH, YA THINK?!?!?!

So, between that and the condition of the pavement and subgrade, that's probably why they did a full rebuild.

ALDOT says no timetable set for I-22/I-65 interchange.

http://www.al.com/news/birmingham/in...le_set_fo.html

This project was supposed to be completed back in October 2014. Another target date was August of this year, but that is not likely to happen either. Talk now is that ALDOT is looking at a Spring 2016 completion date.

I-5 in North Seattle: Redux

A year ago this month, I traveled up and down the I-5 corridor in North Seattle to capture it on my camera, en route to a World Cup viewing party. This time around (with significantly less snow on Mount Rainier), I've returned with my DSLR to do the same!

Do the motorways cope with traffic in rush hours in Seattle or PM6-7 is a constant jam

The Seattle area has considerable reverse commuting patterns.

Greater Seattle has a lot of freeways, but eventually traffic has to deal with either I-5 or I-405 to get somewhere. They run north-south and the urban area has expanded north and south as well. Somewhat like greater Salt Lake City or Miami.

Absolutely, what I noticed in Seattle's freeways is that usually one way sits empty while the other is jammed.

It doesn't help that the number of lanes on each side is cut by half once a day. Going north on I-5 is normally OK until the express lanes merge.

I have seen tower cranes used on other transportation projects in the States.

Reminds me of the interchange at 8 Mile & Woodward in Detroit. It was referred to as a "super-highway" back in the day.

I-84 Waterbury, CT

Malloy: Mixmaster replacement to cost $10 billion

Gov. Dannel P. Malloy says replacing the stacks of highway bridges that comprise the Mixmaster interchange in Waterbury will cost $10 billion based on the latest estimate.

The State Bond Commission today approved $1 million for a design and engineering study for reconfiguring the geometry of the Route 8 and Interstate 84 interchange, notorious for its cumbersome left-lane entrance and exit ramps.

The state Department of Transportation has determined the deteriorating conditions of the highway stacks rule out its complete rehabilitation.

“The Mixmaster is going to have to be replaced,” Malloy said after chairing the bond commission meeting.
Full report: http://www.rep-am.com/articles/2015/...e017690365.txt

$ 10 billion (!) for an interchange replacement? My goodness they can construct 38 High Five Interchanges in Texas for that kind of money. What is wrong with the Northeast?

The combination of Kafkaesque regulations and unions who get paid nearly $100/hr to work at a fraction of the pace that can be accomplished anywhere else in the country. I mean I have no problem with a guy wanting to get paid, but when you think 2 hours of real work is enough for a full day and you want overtime to get off your ass any more than that then I start having a problem. I say this as an engineer who just moved to the NorthEast and started to experience this shitshow first hand. Now I finally understand how all those infrastructure projects in places like New York and Boston end up costing 10x what they would in any other civilized country.

I-5/SR 525 in Lynnwood and Mountlake Terrace

Southwest Snohomish County forms the core of Seattle's northern suburbs, where the growth of suburban sprawl continues to explode. The I-5 corridor in particular has filled out with retail (centered around Alderwood Mall, not pictured in this set) and will see light rail service beginning in 2023. It features an elaborate HOV system for buses and carpoolers, with 3 direct access ramps and several of the state's largest park-and-ride lots.

164th Street SW

This interchange, once the southern terminus of SR 525, features a half-completed HOV direct access ramp. The north side of the ramp (which serves Ash Way Park and Ride) has been the subject of a few small proposals over the years since it forces buses to/from Everett on ST Express route 512 to loop around the interchange.
