Miami drivers are still paying for the Signature Bridge project with something more personal than money: time.
The $866 million I-395/SR 836/I-95 project remains under active construction, with lane closures, highway shutdowns and Downtown Miami detours continuing into October.
The Florida Department of Transportation currently lists December 2029 as the estimated completion date—more than three years away.
IMPORTANT CURRENT UPDATE
The Signature Bridge project remains under active construction. FDOT currently lists an official construction cost of $866 million and an estimated completion date of December 2029.
Multiple closures and detours are scheduled through October 2, while the daytime NW 14th Street closure is currently scheduled to continue through October 30.
Check the official project page before traveling because construction schedules may change.
That means the changing traffic patterns affecting I-395, SR 836, I-95, Biscayne Boulevard and nearby Downtown Miami streets are not ending soon.
Here is the project’s current status, which routes are being affected and what Miami drivers and visitors should know.

Miami Signature Bridge: Current Status
- Official construction cost: $866 million
- Construction started: April 2019
- Current estimated completion: December 2029
- Main roads involved: I-395, SR 836 and I-95
- Contractor: Archer Western–de Moya Joint Venture
- Agencies: Florida Department of Transportation and Greater Miami Expressway Agency
- Current phase: Active construction
- Immediate concern: Lane closures, complete overnight road closures and local detours
The project extends along SR 836 from NW 17th Avenue through the SR 836/I-395/I-95 Midtown Interchange and toward the MacArthur Causeway. The I-95 portion extends between NW 8th and NW 29th streets.

What Is the Signature Bridge Project Supposed to Do?
The project is larger than the six-arch Signature Bridge shown in renderings.
It includes the complete reconstruction of I-395, improvements to SR 836 and concrete-pavement reconstruction on portions of I-95.
Plans include a double-decked section of SR 836 intended to create a more direct connection to the MacArthur Causeway while separating some through traffic from local entering and exiting vehicles.
The finished project is intended to improve safety, traffic flow and connections between Downtown Miami, Miami Beach, PortMiami and surrounding neighborhoods.
Those long-term promises, however, must be balanced against the disruption drivers are experiencing during construction.
Which Miami Roads Are Being Affected Right Now?
FDOT’s current schedule includes multiple closures and detours between September 27 and October 2, 2026.
I-95
Up to two lanes may close overnight on northbound and southbound I-95 between NW 8th and NW 29th streets.
I-395
Eastbound and westbound I-395 lanes may close overnight between I-95 and Biscayne Boulevard.
SR 836
Portions of eastbound and westbound SR 836 are scheduled for overnight lane closures and complete closures.
The eastbound closure at NW 17th Avenue requires drivers to exit and follow a local detour before reconnecting with I-95, Biscayne Boulevard or the MacArthur Causeway.
Biscayne Boulevard
Nighttime closures may affect Biscayne Boulevard between NE 11th Terrace and NE 14th Street.
Daytime single-lane closures may also occur in this area.
Downtown streets
Additional closures and detours affect portions of:
- NW 14th Street
- NW Miami Court
- NW 1st Place
- NW 2nd Avenue
- NE 13th Street
- North Bayshore Drive
NW 14th Street between NW 3rd Avenue and NW 1st Place is currently scheduled to close Monday through Saturday from 8:30 a.m. to 4 p.m. through October 30 for the erection of precast roadway segments.
Construction schedules can change because of weather, special events and operational requirements. Drivers should check FDOT’s current project page before traveling.
Why Has the Project Become So Controversial?
The Signature Bridge was expected to become a recognizable part of Miami’s skyline while improving one of the region’s most complicated highway connections.
The controversy centers on three issues:
1. The extended timeline
An earlier completion target was 2024. The official estimate is now December 2029.
For residents who use these roads regularly, that means several additional years of construction activity and changing traffic patterns.
2. The cost
The official construction cost is currently listed as $866 million, compared with an earlier reported figure of approximately $818 million.
The official budget should not be confused with separate contractor claims reported in ongoing litigation.
3. The daily disruption
Miami already struggles with congestion, unpredictable travel times and limited transportation alternatives.
Lane shifts, overnight closures and downtown detours add another layer of uncertainty for commuters, residents, visitors, cruise passengers and airport travelers.
What Do the Project Lawsuits Allege?
Lawsuits reported in 2026 include allegations involving design errors, concrete problems, delays and more than $400 million in claimed additional contractor costs.
Those allegations are part of legal disputes and should not be interpreted as a confirmed increase in the official construction budget.
FDOT continues to list the project’s construction cost as $866 million.
This distinction matters: the officially listed project cost and the additional amounts claimed through litigation are not automatically the same thing.
Miami Residents Can Meet the Project Team on September 30
A monthly project stakeholder meeting is scheduled for Wednesday, September 30, 2026, from 10:00 a.m. to 11:00 a.m.
Residents can attend in person at the construction field office at 1007 Parrot Jungle Trail or register for virtual participation.
A separate project-team pop-up is scheduled from 11:00 a.m. to 1:00 p.m. at Paramount Miami Worldcenter, in front of “The Globe,” at 850 NE 2nd Avenue.
Residents can use these events to ask about:
- Current construction progress
- Upcoming lane closures
- The December 2029 timeline
- Changes affecting their neighborhoods
- Planned work around Downtown Miami
- How the finished highway configuration is expected to improve traffic
What Should Miami Drivers Do?
Drivers do not need to understand every engineering detail, but they should plan for changing conditions.
Check the closure schedule
Review the official project page before nighttime or early-morning travel. A familiar ramp or road may be unavailable even if it was open the previous day.
Use live navigation
Real-time navigation can help identify crashes, unexpected backups and temporary construction detours.
Do not rely entirely on a route saved several months ago.
Leave a larger travel buffer
Allow additional time when traveling toward:
- Downtown Miami
- Miami Beach
- PortMiami
- The MacArthur Causeway
- Wynwood
- The Adrienne Arsht Center
- Kaseya Center
- Miami International Airport through Downtown routes
Cruise passengers and airline travelers should avoid planning an arrival with little room for construction delays.
Follow posted detours
Do not enter a closed road or attempt to drive through a construction area because a navigation application has not updated.
Temporary signs and directions from traffic personnel should take priority.
Will the Finished Project Be Worth It?
That question explains why the Signature Bridge continues to generate such strong reactions.
Supporters see a major infrastructure investment that could improve safety, remove problematic traffic movements and create a recognizable new Miami landmark.
Critics question whether the eventual transportation improvements will justify the cost, years of disruption and extended completion schedule.
Both perspectives lead to the same practical reality: Miami residents must continue navigating the construction while waiting to see whether the completed project delivers its promised benefits.

The Bottom Line
Miami’s Signature Bridge is not merely a future skyline feature. It is part of a much larger reconstruction affecting I-395, SR 836, I-95 and several Downtown Miami streets.
The official project cost remains $866 million, and completion is currently estimated for December 2029.
Until then, closures, detours and changing traffic patterns will remain part of traveling through central Miami.
Drivers should review current conditions before leaving, allow additional time and follow official detour instructions.
The larger question remains open:
After years of construction and an $866 million price, will the completed project be worth the wait?
