The grooved California concrete highways are famous, they were made like that on purpose and have been that way forever (at least 30+ years)

There is a section of Autoroute 440 in Laval, Canada that has that same kind of surface. But newer concrete paved freeways in Quebec have smooth concrete for whatever reason, I guess the grooves didn't give much benefit.

Actually, those grooves look like they were made when the concrete was poured and are there to provide additional traction when it rains. Water on smooth concrete is a recipe for disaster. The only real issue with this type of grooving is an increase in road noise.



That's like comparing apples to oranges. Asphalt roads, like those in the Arizona pictures, do not need to be grooved because of their porous nature.
Wouldn't it increase fuel consumption due to smaller contact patch?

I had ambition of posting some photos of grooved concrete from various US states yesterday, but didn't find the time, but, a lot of states use longitudinal tined concrete. It reduces road noise compared with conventional longitudinally tined concrete. It can be retrofitted onto an existing concrete slab using diamond grining, however, most often the tining is actually applied to wet concrete at the end of the screed.

The grooves are there to help drainage and to reduce the risks of hydroplaning. Yes. But the slots are for supporting load.
Load transfer restoration (LTR), also called retrofitted load transfer, refers to the placement of load transfer devices across joints or cracks in an existing jointed concrete pavement. This increases the transfer of loads across these discontinuities, thereby reducing pavement deflections and subsequent pumping, faulting, and corner breaks.

Houston area toll roads

The HCTRA operated toll roads in the Houston area become more user friendly for sporadic users. Very soon, drivers who don't have a toll tag can pay the toll on the redesigned HCTRA website.

Originally, the electronic toll roads could only be used with a transponder / tag. Motorists without a transponder were automatically in violation, and had to pay for that. This is different from many other agencies who have license plate tolling (for example the NTTA in the Dallas-Fort Worth area has a system called 'ZipCash').

Because of the language used when voters approved establishing HCTRA, saying the agency shall collect tolls at the time of tollway use, the agency doesn’t send bills for unpaid tolls and only notifies people with violations. The first violation comes with an additional $5 fee on top of the tolls owed, with the second and subsequent violations costing $33.

Evans said people who pay before receiving a notice, referred to as a “missed toll” can go online once the system is active and pay the tolls, plus a $1.50 administrative fee. The crucial part of paying tolls is to do so before they become violations, she said.​

Tampa Bay Express


TBX passes in overnight vote; $6 billion in funding approved

After hours of public comment, the Hillsborough County Metropolitan Planning Organization has voted to move one step closer to getting funding for the Tampa Bay Expressway project.

The board voted 12 to 4 early Thursday morning to approve $6 billion in funding for TBX, which is designed to add toll express lanes on Interstates 4, 75 and 275 in Hillsborough County to help reduce traffic congestion on the county's busy freeways.​

Full report: http://www.abcactionnews.com/news/h...ws/decision-day-for-controversial-tbx-project

This megaproject consists of 80-90 miles of new toll lanes (express lanes) along I-4, I-75 and I-275 in the Tampa Bay area. It's one of the largest express lane projects in the U.S.

Very necessary, but extremely unpopular within the City of Tampa. I'm still not sure why, though.

This is a project that will cost billions, not improve traffic, and tear through the center of the city. What is needed is an alternate highway that goes east-west. Here in Seattle the tolled express lanes on the 405 made traffic worse for example.

Many express lane projects have been very positive for traffic flow though. I think the performance of the I-405 express lanes is more of an exception than a rule.

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).

I don't think that that will work. It is just a stop-gap that will be quickly filled. A larger, deeper, multi-modal program is needed.

Some of the elements, like the airport interchange reconfiguration, are probably worthwhile, but I question the need for express lanes along an existing freeway.

Wrt to houston, I wish there was a uniform license plate tolling system for the whole state and you didn't have to stress with tags at all.

I was in Houston last month and while heading back to college station I sat in traffic for a good 2 hours on 290. Should've taken the grand Parkway but couldn't because I don't have a tag. It's nice that this is changing.

Gateway Expressway Animation - April 2016.

Hopefully this will get built. Look and enjoy

The Gateway Expressway is decades overdue so it will be very welcomed. The tolled express lanes are ridiculous, they are taking away an existing general purpose lane to toll it. They did the same thing here in Seattle on the 405 and all it did was make traffic worse. Greed at its finest, they made millions more than expected though. :bash:

A general purpose lane or HOV lane? Normally these tolled express lanes / managed lanes / HOT lanes are a conversion from an HOV lane to a tolled lane.

Converting regular lanes into toll lanes wouldn't be very popular.
