What Exactly Is Miami Getting With The $800M Signature Bridge? A Breakdown

With FDOT now given the green light to move forward with the Signature Bridge project, here is a look at what exactly is being done.

In total, $802 million is being spent – but not all on the bridge itself. The breakdown is:

  • I-395 Reconstruction (FDOT) – $556 million
  • SR 836 Improvements (MDX) – $186 million
  • SR 836 Westbound Connector (FDOT) – $35 million
  • I-95 Pavement Reconstruction (FDOT) – $25 million

At the ground level, a 55-acre park known as Heritage Trail will be created. The highway span will be elevated from its current 19 feet to 63 feet at NW 3rd Avenue, allowing more sun to shine down.

Traffic flow on the highways, including on the Dolphin Expressway, will be significantly improved with a complete rebuild adding more capacity and better ramps. Highlights include a viaduct that will allow eastbound drivers on the 836 to bypass the Midtown Interchange altogether, while another lane will be added for those connecting to northbound I-95 – a problem area for decades. Confusing left-hand exits will be eliminated altogether.

While the benefits of burying the highway in an underground tunnel were widely recognized, it was deemed too expensive, disruptive, and risky. The cost would have ballooned by an additional $1.3 billion, bringing total cost to over $2 billion. It would also mean shutting major traffic arteries during construction and permanently eliminating Miami Beach’s evacuation route during storm lockdowns.

The second-ranked team had included MCM, a contractor involved in the FIU bridge disaster. With the bid challenge ended, FDOT is now free to conclude a contract with the top-ranked team and begin work on a project that has been years in the making.

So much more than ‘just a bridge’. It will become an icon and create a great impression on those arriving from the port on cruise ships.

The i95n to 836 westbound connector is huge.

The 836 east to i95 north connector should be a part of this. That alone would save millions a year in car and truck delays. TNM.. are you confident that it’s not included??

They are doing an east bound to I-95 connector. I have read about it several times on the MDX site. It will be on the right side of the highway eliminating the need for those entering the highway at 12th to have to cross over to the left.

So hundreds of millions of dollars available to build a new highway viaduct over existing 836 but no money to build a few short miles of Metromover or rail. SMH.

No public transport option in this equation. Hope Miami Beach builds HUGE parking decks for all the visitors this new highway will allow. Miami Beach keeps discouraging drivers on their strip of land and DOT is now building them a elevated roadway to encourage more and more vehicles on the roads.

Beautiful park underneath.. creates green space and connects the Omni, A&E district with Park West, MiamiWorld Center and downtown.

“The highway span will be elevated from its current 19 feet to 63 feet at NW 3rd Avenue, allowing more sun to shine down.”

– Although I still feel a tunnel between Downtown and Brickell should have been built first. The fact that this bridge will be elevated to 63 feet makes a difference. The current height of 19 feet is just too low and makes the overpass aesthetically dreary. Let’s hope the park will also be nice and have shaded areas and that it will be used by residents and not only by vagrants… Hey! One can hope 🙂

No one wants to hang out under a massive horribly noisy expressway whether it’s 19 feet or 63 feet in the air. Look at I-95 on the south side of Miami River. It is far higher than 63 ft. The land is worthless and no one goes there. They tried to put in basketball courts which some people use but it’s all still a dead space.

Those Basketball courts are always busy at night, and Jose Marti Community center is active.
Much better to have space under 836 than the current mounds of dirt.

A lot of necessary improvements to highways: I-395, SR 836, I-95 Concrete, Signature Bridge, plus + 55 acre park underneath I-395.

So instead of tearing down highways we’re going to get a much bigger and expanded highway (albeit elevated) through downtown.

Great article to show where the improvements are going!Hopefully all can quit calling it the “$802M Bridge”. Only drawback is that this is a major reconstruction to the interchange and even worse, massive traffic headaches ahead. But the clock is ticking, lets get this project going.

A billion dollar boondoggle. IT IS A LAND-BRIDGE I’m a waterfront city. Am I the only one that finds this to a huge waste? So sad. Congratulations Miami on the approval of your “Big Dig”…I look forward to the comedy (and tragedy) of errors to come.

No, you arent the only one.
Just like the people that whined, bitched, and moaned about the Port Tunnel…
“Eeeeewwww…. it’s a waste of money…..eeeewww…. it’s just going to leak…..eeeewwww Miami is stupid”.
Engineers, men of action, and other producers always have to carry the weight of those comments from whiners.
Then, great things get done.
Rather than appreciate the work of the thoughtful few, the whiners just move on to whine and complain about something else.

They are STILL implementing and constructing the express lanes on 95! And that’s a minor project compared to this one.

TOO MUCH VISUAL CLUTTER! Imagine this thing will sit yards away from both the Arsht Center, Frost Museum and nearby condo towers. There’s already plenty of architecture there. If the intent was to clear the area of the obtrusive I-395, this will do the same and then some. This is a case for Less is More!

Our city should use the money to improve public transportation, extend the metrorails, and build better bike Lanes. This another way for miami to “peacock”. I think we are still making the Bayside observation tower…. Sigh.

From all the failures that the city of Miami always does, this is the worse ever.. did you just read that is gonna cost 800 million dollars? with the country in crisis right now and water levels rising, there is so many other things that this money could be spent with. like creating a train or subway system that actually works like in the major cities in the US to improve traffic. This architecture is not even original, it totally copied the JK bridge in Brasilia, the capital of Brazil. Google its pictures.

Honestly, for 1.3 billion more, they should put it underground. Wait another 5-10 years, save another $500 million and finance the rest and put it underground.

Putting this underground would be an actual huge improvement.

This is just a makeover.

I used to joke that as soon as they are finished rebuilding the highways they start over again – but it’s not a joke. Has 836 never not been under construction? One big project after another.

This project will be such a headache for those going to/from South Beach.
