Interstate 17 in Arizona

A new project to add capacity on I-17 north of Phoenix appears to gain traction. $ 3 million has been allocated to design two reversible lanes in the median of I-17 from Black Canyon City to Sunset Point, a good 40 miles north of Phoenix. This is the stretch of freeway with long grades. I-17 climbs from 2,000 ft in Black Canyon City to some 3,200 ft near Sunset Point. The reversible lanes would be approximately 8 miles long. Construction is still 6-7 years away though.

Interstate 35 in Texas

A project to widen I-35 from four to six lanes south of Waco has been completed. The $ 169 million project widened 10 miles of I-35 between Bruceville-Eddy and Waco.

Depends on your location and willingness to pay.

If you live north of 522 and don't pay, likely it's way worse.

But if you live south of 522 and do pay, I'd gather it would be way better.

Its a general purpose lane. There are no HOV lanes in the Tampa Bay area, one thing which I think is a good thing.

Of course its better if you pay, but for anyone in the general lanes its worse. Not to mention increased traffic on I-5 and surrounding roads. I'm lucky that with my work schedule I can generally avoid the whole mess since you can use the HOV/HOT lanes after 7pm for free and without the HOV requirement.

And for bus riders and vanpool drivers, it's also working...

And why would a lack of HOV lanes be a good thing? You please both sides by (a) adding priority for buses and carpools and (b) not taking a GP lane to do so, in most cases.

they tend to cause a lot of accidents from speed differential
and typically are inefficient (they will speed up a few people, but if it was a general lane, everyone would speed up a little, but globally, more time will be saved)

Traffic flow in Tampa is horrendous to begin with. Improving throughput from the suburbs may actually help emissions, rather than harm them, by reducing standstill traffic.

Most of the takings for this project had already been enacted in previous projects. The most controversial section, 275 north of 4, doesn't appear to have more than a few dozen takings in its most recent iteration. It's unfortunate, but these properties had already had their ultimate value diminished when it was I-75 cutting through there 50 years ago.

Furthermore, I've noticed FDOT goes above and beyond many other jurisdictions in the Sun Belt as far as sound mitigation.

Cost is, and has always been, only an argument for those opposed to the project to begin with.

I'm failing to see how separating suburban through traffic from local traffic won't help traffic flow - and I'm saying this as someone who drove from Busch to Downtown on a regular basis in recent years. Everyone gets jammed at the I-4 bottleneck. Getting the suburban traffic out of the way will alleviate much of the issue.

No disagreement that an alternative east-west route is needed, but good luck getting Hillsborough Ave converted to a freeway - that's a political nightmare waiting to happen. Creating anything north of there, including the once-planned outer belt, will run into even worse suburban politics.

As far as I'm aware, these express lanes in the Tampa Bay Area are all planned to be new capacity, perhaps taking an HOV lane at worst (I'm not sure if the Tampa area actually has many HOV lanes).
There are no HOV lanes in Tampa - blew my mind when I moved there.

When I used to commute from Everett to Seattle I witnessed why they don't work. Basically at every on/off ramp traffic came to a stop as buses, vanpools, and cars cut across all lanes to get to the HOV lane. Traffic would flow much better if this didn't occur. HOV lanes also seem to encourage camping in the left lane which is for passing. There's a reason people joke that in Seattle the right lane is the passing lane. Very few countries outside of the US have HOV lanes, they just aren't efficient.

Exactly.

I have a GTG pass but not the HOT one. Luckily don't really need it.

The TBX project won't separate thru traffic from local traffic. You're assuming those people will use the HOT lanes which only a small percentage will. Your second point is valid, thats what created the mess in the first place.

Plenty of East Pasco and New Tampanians who will use those lanes to get to Disney/the beach 25 minutes faster, I'd say.

Well, during peak hours the buses generally are constrained to only using the HOV direct access ramps at places like Lynnwood TC and Broadway in Everett. The solution is obviously to build more of these and open up a limited few to carpools.

And the cutting-across is a huge issue, even in non-HOV situations like the 45th/Ship Canal-520-Mercer weave. The latter pair is particularly bad and probably contributes greatly to downtown traffic, and won't be solved anytime soon.

I hope they can move on to making the area around the junction look less like a concrete wasteland.

That's indeed going to be the case once construction is complete. Riverfront Blvd will be rebuilt and the old run down and parking lots around it will be demolished for a new wave of development.

Downtown Houston freeway realignment and removal plan

This should be interesting if carried onward as proposed by TxDOT. Maximum freeway lane point-count: 28 lanes!

I think it was already discussed back when the article was posted (and linked to) in april.

Anyone know if there's news?
