I-20, Atlanta, GA

A major buckle has closed I-20 westbound 'indefinitely' near Gresham Road in Atlanta, due to a gas leak.

I-20 is one of the two major detour routes for the collapsed bridge of I-85.

...actually, yes. There is only one more highway in that corridor, apparently.

Maybe they should look at a temporary commuter rail line for help? Of course, if it works, it can be permanent.

This must be a boon for MARTA. I wonder how much revenue the city has, and will continue to collect from this. Not saying it's a good thing, of course. The freeway shutdowns have most likely been bad for the region's GDP.

probably negative if they are boosting service with expensive overtime, rented vehicles, emergency repairs etc etc

Interstate 69

Possible alternatives for the I-69 Ohio River crossing at Evansville, Indiana.

I-71 Jeremiah Morrow Bridge, Ohio

The old span of the Jeremiah Morrow Bridge in Ohio was demolished today using explosives. It is the tallest bridge in Ohio and part of I-71 between Cincinnati and Columbus.

The implosion did not go entirely as planned, one segment did not go down, a second attempt later today brought that section down as well.

I-10 Houston

There are 33 lanes planned on I-10 / I-45 in Downtown Houston. This is part of the $ 7 billion Downtown Freeways reconstruction and I-45 express lanes.

33 lanes??? WTF! That's crazy.

The widest section of highway near me is 10 lanes including exit lanes, and that's only for a mile.

They plan to remove I-45 around Downtown. As a compensation, I-10 and I-69 will be expanded. I-69 will be constructed in a 21 lane tunnel. I-45 will get express lanes all the way to Beltway 8 in North Houston.

I must say $ 6 - 7 billion doesn't sound particularly expensive for such a large urban project. I think this exceeds Boston's Big Dig in scope.

In Dallas, they are planning on a project to relocate I-30 entirely. By doing so, 345 and 45 would be demolished and 45 would tie into 30 as would 175.

The Dallas Horseshoe Project is pretty much complete now with minor road work. All bridges are in operation. Traffic has vastly improved as a result and it looks great, especially lit up at night.

Construction work has already started and is in progress to turn 175 in the center of Dallas into a city roadway by tying it into 45 toward the Trinity, which is in preperation for the overall realignment of I-30.

$2.8bn at 1982 prices probably sounded quite reasonable for the Big Dig. As it happens, converted to 2017 prices that $2.8bn comes to $7bn. And if you apply the Big Dig's 190% cost overrun to the Texan scheme (admittedly unlikely) you get a less reasonable sounding $20bn...

I-35E / US 67 Southern Gateway, Dallas, TX

The winner of the Southern Gateway segment 1 & 2A has been selected, Pegasus Link Constructors. They consist of Fluor and Balfour Beatty. They made a $ 589 million bid for the expansion of I-35E and US 67, known as the 'Southern Gateway' project.

With this project, they will expand I-35E to 5+2+5 lanes, with 10 GP lanes and 2 non-tolled reversible express lanes. In addition, US 67 will be expanded to 3+1+3 lanes, with a single non-tolled reversible express lane.

Pegasus Link Constructors is currently mopping up the 'Dallas Horseshoe Project', ahead of schedule and on budget. The Southern Gateway Project borders the Dallas Horseshoe Project, so they only need to move south to begin construction.

Segment 2B is a separate contract and is a regular six-lane widening of US 67. The whole Southern Gateway Project originally consisted of tolled express lanes, but the tolls were dropped in 2015 after public opinion and Texas lawmakers turned against the tolled expansion of many projects.
