Description

Specialties

MDX’s commitment to Miami-​Dade County extends far beyond the construction and maintenance of our expressways. MDX is committed to providing equal opportunity for all businesses to participate in our procurement and contracting process by implementing checks and balances to ensure an open, transparent and competitive procurement environment, while promoting the local economy. In fact, MDX awards over 40% of contracts through its Five-​Year Work Program to small and local businesses, creating over 10,000 new jobs in the process.

MDX Cash Back Toll Dividend Program is MDX’s free customer loyalty program. MDX has evolved the Advantage program into a new one that is more beneficial to you. The new program is called the MDX Cash Back Toll Dividend. If you were previously enrolled in the MDX Advantage Program, you are automatically enrolled in the new Cash Back Toll Dividend Program. The way the new program works is simple. Each Fiscal year (July 1st to June 30th) after the close of its financial books, MDX will declare a toll distribution of dividends to members of the new dividend program. This is after the agency meets its financial obligations, including making its annual principal and interest payments, meeting its senior debt coverage ratio, and covering its operation and maintenance costs. MDX will return the toll revenues directly to its customers through the Cash Back Toll Dividend Program. The next open enrollment period will occur in 2016.

History

Established in 1994.

The Miami-​Dade Expressway Authority (MDX) was created by the State of Florida and the Board of County Commissioners of Miami-​Dade County to serve as an innovative transportation agency dedicated to the enhancement of mobility in Miami-​Dade County.

MDX is funded entirely by toll revenue. We receive no state or federal funds; no sales tax, gas tax, property tax or half-​penny sales tax. Tolls collected are reinvested for the planning, design, construction, operation and maintenance of five of the most critical roadways in Miami-​Dade County:

State Road 112/​Airport Expressway

State Road 836/​Dolphin Expressway

State Road 874/​Don Shula Expressway

State Road 878/​Snapper Creek Expressway

State Road 924/​Gratigny Parkway

Feel like I’m getting robbed every time I drive around Miami! Side roads are now consumed with traffic do to people trying to avoid all of the tolls, somehow MDX has pulled A fast one on the people of Miami. Found this Grassroots site NOMORETOOLS. US great idea to give us the Power to vote on tolls!!! MDX you should be ashamed for robbing your own people!!!

I received multiple bills in the mail from the Miami Dade Expressway Authority for toll violations. The initial problem is that the pictures included with the bills are of cars I’ve never owned or driven. One was a Dodge Caravan and the other is a Mini Cooper. My plate was registered to a 2012 Toyota Camry that I leased for my ex-​wife when we were married.
The plate was registered to me but when my ex-​wife turned the car in to the dealership when the lease was matured, it seems as if the plate was stolen from there or perhaps wherever the bank takes the car for processing. I know my ex had to get a new license plate because she needed one in her name and she purchased a Subaru not a Mini or a minivan.
I called the MDX and received instructions saying that I had to submit a Registration Cancellation form which I can get from a tag agency. I went to the tag agency to get the form but I was told I needed to supply proof that I no longer owned the car. My ex-​wife was kind enough to contact the dealership and a few weeks later I received paperwork showing the Toyota was returned on 10÷4÷2014. I took all of this back to the tag agency and was issued a Surrender LP/​Cancel Reg form dated 6÷15÷2015.
I called the MDX and they instructed me to download and fill out their Affidavit and return all the documentation I have to them via fax which I did. A few weeks later I received a letter from them stating they declined my dispute because the Surrender LP form was dated 6÷15÷15 and the violations were made prior to that date. They neglected to acknowledge the vehicle’s Lease return paperwork which predates any of the fines or letters I’ve received.
I called them up, waited 30 minutes on hold only to be told that now I’d have to get a notorized letter from the DMV stating the exact same thing all over again. Enough is enough! Why do I as a responsible citizen and tax payer have to be pestered because these people can’t put together the dots and see the big picture? I’ve spent plenty of time as has my ex-​wife along with handling these issues during my working hours. It’s a bill for $ 25.80 for goodness sake. It seems like that if MDX can’t get the money, they want their pound of flesh instead.

Scammers. I have sun pass and they keep billing me extra.
I keep getting bills and every time I call them, they say to call sunpass and sunpass says everything is good… Continuous circling

The system seems to be much improved now. We make several trips each year with a trailer in tow, so the discounts I get when using a transponder are well worth the $ 5 cost of the stick-​on one. Also, when I got a bill because I forgot to update a new license plate number at
, the bill automatically reduced from $ 3.50 to .$.55 when I updated my info online. That was much appreciated.
I think it’s been about two years since the last time I was billed for someone else’s vehicle — either the system is working better, or else that old junker is off the road now. :-)

Back in the 1990s, MDX was a far different organization. They did a pretty good job maintaining a few toll roads throughout Miami-​Dade County, and they were well and safely kept.
Flash forward to today. The safety and ease of use are gone. The money’s all being spent on ridiculous things like half million dollar effects lighting systems in toll gantries and super expensive non-​native imported palm trees. The only guiding factor in MDX project designs and maintenance seems to be increased profit from open road tolling, and elimination of alternate routes which people could otherwise use to get around the city. Roadway capacity seems to be sized merely to allow everyone to barely crawl down the road at 20 mph, getting tolled by the mile, and not really to get anywhere.
MDX has kidnapped us and holds us hostage for toll dollars to get anywhere.
The ongoing constant construction zones are ridiculous. You get half a second to make a lane shift before being dumped head on into a concrete wall!!!

Can someone in authority please launch the investigation already? These guys have unofficial policies in place to fraudulently charge the citizens and visitors of Miami-​Dade County. They should be shut down for criminal business activities.
After they sent me a bill for charges so late that I cannot verify whether they’re duplicate or not, I dispute the invoice so as to effect my lower SunPass price. They lower the bill, apologize, and then seven days later I get an invoice stating that my account is in collections and my vehicle on hold.
I disputed again…
(if you would like to copy/​paste/​edit/​use in your own disputes, I welcome you to, as it fits the max characters on the MDX submission form.)
I wrote this to them this morning:
I rec’d your 5⁄26 email: «since you are a SunPass customer, we have adjusted the account to SunPass rates lowering your balance to $ 7.10. We sincerely apologize for any inconvenience this may have caused!»
I accept your apology-​but, one week later, I attempt to pay, and yet I can’t!
You’ve reneged via invoice 6⁄2 & put my account in collections, my vehicle reg on hold.
I can’t pay the $ 7.10 that you’ve requested because you’re so hellbent on sending me to collections. How can you send me to collections when you’ve just admitted error & adjusted my bill in my favor???
You allowed less than a week btwn the notice of resolution and sending my account into collection/​vehicle hold. Not 10 days, not 15 days, not 30 days, a week! You owe me another apology for the incredible inconvenience having to waste more of my time.
It is alarming to deal with a government entity that behaves like Dr. Jekyll and Mr. Hyde. Please improve your consistency!

Same things that most people already wrote about this company.
I received a $ 39.10 bill (first time I get a letter although they claim I own payment adjustments and fees) and stating that my vehicle registration is on hold.
I traveled to florida last january and received bills from Florida Turnpike, Sunpass and Toll-​by-​plate, all of them with payment adjustment. Will it ever stop??? Is there any other company that can eventually reach me and say that I own them some money?
And yes, they have a picture of my car, all kinda blurry except by the plate which is shinning and well defined. Did they show the dates of occurence? No.
Very suspicious.
Can anyone do something, anything, about this company? It really seems corrupted.

MDX though it was cute to send me a $ 288 bill for 3 months worth of tolls, but is only giving me 2 weeks to pay. The lady explain to me when you reach a $ 3 threshold they send a bill. My question is why didn’t they send a bill before? I don’t think it is fair how they have been racking up my bill for 3 months, but only give me 2 weeks to pay. It is easier to pay a $ 20 toll invoice, but it is not easy to pay $ 288 at once, specially when you were not expecting this. It is sad how I called them before to make sure I did not have an outstanding balance and they said everything was ok. I have reached a point where now I start to record my calls with these idiots to be able to save my ass!!!
Don’t even think of trying to negotiate this with them because they won’t. The customer service is crap and they tell you nothing can be done to break this up even though it was an error on their end!!!

I received a debt collection notice for MDX… and I have never been to Miami in my life. I live out of state and have never driven on their roads.
When I call they are telling me I have a totally different license plate than I have. I also never received any invoices (as they claim) before it went to the debt collectors.
What a scam, now I have to go through this work to fix their mistake.

The same thing that happened to Mike D. of Fort Lauderdale 9⁄2013 is happening to me. No notice whatsoever, and all of a sudden I get a collections notice for $ 17.96, but have a balance of $ 75.34. The collections notice doesn’t even include my license plate number, so I thought it was a scam over the mail. I called the number on the statement but mdx answered. the agent was nice but not really helpful. He referred me to the website to see all the invoices they are talking about. They all include a picture of my license plate, but they don’t say where the toll violation occurred. So, are they billing made up toll violations?

Sunpass here, sunpass there. MDX here, MDX there. Are they two different fckng things? Why is it that I pay and paid all my sunpass balances on my transponder but yet I get bills from MDX?! When is this whole toll bullsht gonna stop? This city relishes in raping its residents. When its not the tolls, its the red light cameras. Nobody cares, nobody protests. Everyone I guess really likes wasting money for no reason. I travel towards North Florida past Gainesville and I seem to come across less tolls. I really hate this city.

The new tolls are ridiculous. There has to be a way to stop this. I am spending now almost $ 8.00 a day just to drive from Downtown to El Doral.

I hope that everyone that is in any way associated with MDX gets cancer… no, you know what, cancer doesn’t deserve that…
Miami is rated the most miserable city in the country and MDX is definitely a great big part of that… the tollmageddon that is happening here is unbelievable… the I-​95 never had tolls, the 836 used to be one east bound toll… now there are going to be 5 or 6? I-​95 has the lexus lanes that are useless as they are usually backed up before the regular 95 traffic… one east bound toll on the 112 is turning into 4 tolls, 2 in each direction… and they were even talking about tolling US-​1 kendall and killian drive?! soon you won’t be able to get anywhere without MDX raping you for more money… as if the gas and car insurance wasn’t bad enough…
and our public transportation is utterly useless… so it’s either pay it or just expect it to take 2 hours to get anywhere…

MDX are theives, you guys are building one more toll ont he 836 to further nail is in the behind as if driving in Miami was not expensive enough, traffic is just as congested as it has always been or worse, and my paychecks are going to you guys, 1200 dollars a year in tolls to commute from homestead to downtown Miami, horrible, and the fines and license suspensions is extortion at its best, we need free roads like in California

I hadn’t written a ranting, one star review in a while, but my recent experience with what MDX hath wrought inspired such a writeup. As it were, it’s not an empty rant. I was inconvenienced by a traffic jam due to their toll gantry construction.
You know the added congestion on 836, and the constantly switching lanes to the Palmetto? Yep, that’s their fault! The delays and new toll gantries on SR112, that close some lanes at night and day while they install the SunPass equipment? Yep, MDX fault as well! The added cost to drive, collecting money on roads that were operational and paid for before I learned to drive? You get the idea…
With the constantly increasing tolls you’d think traffic flow would have improved, or red lights would be synchronized. well they haven’t. In fact I have yet to see one useful product out of this agency. If I considered a tin foil hat a fashion accessory, I’d say the only purpose of MDX would be to discourage people from driving.
If MDX were a restaurant, they’d be a recurring star on a certain TV stations bad restaurant segment and shut down by the health department.

No stars for a ripoff scam that is MDX. My wife received a notice from a collection agency for $ 268 and a notice of suspended license for unpaid tolls. I’ve always had a Sunpass with a positive balance, but MDX claims the transponder must not have activated for some reason and had previously sent notices to my house. NOT TRUE. How convenient that we receive the letter from a collection agency now that it’s too late to contest in court, but we never saw any previous correspondence when we had the chance to pay just a fraction to clear this all up. THIS IS A SCAM against responsible citizens and needs to stop.
