Will there be a park and ride lot on I-75 and Pines Boulevard?

  • A Park and Ride Lot at the Pins Boulevard Interchange was evaluated during the PD&E Study, but it was not included as part of the preferred alternative. An additional evaluation of the area around the Pines Boulevard Interchange would be necessary to determine a future alternative.

Will there be Express Bus services on the 75 Express Lanes?

  • Express Bus services along the 75 Express Lane is planned to begin after the opening of the Express Lanes. FDOT is currently working with local partners to define who will operate the service, determine routes and times of operation.

What is weathering steel?

Weathering steel is a group of steel alloys (material made of two or more metals) which were developed to eliminate the need for painting, and form a stable rust-like appearance if exposed to the weather.

Are all steel bridges at the I-75/HEFT interchange going to be weathering steel?

Yes, they will. The project consists of four steel bridges. The locations are listed below:

  • I-75 Southbound Express Lanes to Turnpike Northbound & Southbound
  • Turnpike Southbound to I-75 Southbound and Miami Gardens Drive
  • I-75 Southbound Express Lanes to Turnpike Southbound
  • Turnpike Northbound to I-75 Northbound Express Lanes


What is the reason for using weathering steel?

Painting and repainting bridges can be expensive. For information, see below FDOT’s historic budget for repainting structural steel bridges:

  • 2012: $28,500,000
  • 2011: $27,400,000
  • 2010: $25,000,000
  • 2009: $25,500,000
  • 2008: $26,300,000

 Repainting a bridge involves the following:

  • Mobilizing equipment
  • Traffic control plans & detours
  • Removal of existing paint & surface preparation
  • Containment and environmental monitoring
  • Disposal of hazardous waste
  • Inconvenience and expense to the traveling public due to traffic slow downs

The use of weathering steel provides an initial cost saving range from 7-10% compared to painted steel. FDOT spends $25-$30 million each year repainting existing bridges in addition to the initial painting costs associated with new steel bridges. Weathering steel can eliminate maintenance costs of painting structures with no reduction in service life.  The use of weathering steel is consistently evaluated as a primary choice for structural steel girders unless there are environmental conditions or overriding aesthetic considerations.  

The use of weathering steel at the I-75/HEFT interchange will avoid traffic delays since these structures will not require repainting. In order for an existing bridge to be rehabilitated or repainted, it requires the closure of multiple travel lanes and shoulder lane.


In addition, an estimated $3,595,000 can be expected on savings for the bridges noted on the table above for the repainting of these structures. Note that steel bridges are typically repainted multiple times during the life of the bridge. Therefore, it provides significant savings to the Florida Department of Transportation and tax payers.

Weathering steel has been proven to be effective for corrosion control, low maintenance and cost effective. The minimal future maintenance requirements of weathering steel bridges greatly reduces both the direct cost of the maintenance operations and the indirect costs of traffic delays.

Is weathering steel as durable as painted steel?

Weathering steel is as durable as painted steel. The structures design life will not be impacted by the use of weathering steel and will meet the 75 years requirement.

General Construction Questions

How can I find out about future construction projects in my area?

  • You can contact the FDOT District Four Public Information Office at 1-866-336-8435 to learn about any future projects in your area 

What kind of impacts can I expect during construction?

  • During construction FDOT works hard to minimize any project-related impacts.Some impacts you might experience during construction are as follows: increased dust, additional noise, reduced speed limits, temporary detours and/or lane closures, heavy machinery and equipment moving in and around the construction zone, and project personnel moving in and around the project area.

How do I file a vehicle damage claim?

  • Call the highway patrol at *347 to file a police report, and if possible, take photos of the damage once you are located in a safe area. The motorist should contact the I-75 project's public information office at 954-584-2754 or send an email to The public information officer will send a claim form to the motorist. Once the form is returned along with the police report, the claim will be forwarded to the contractor for investigation. The contractor will then investigate this claim and respond directly back to the party making the claim. This is a Third Party claim between the contractor and the owner of the vehicle. FDOT is solely responsible for monitoring the claim to ensure it is closed out in a timely manner. 

What can I do to get safely though the construction roadwork?

  • Below are tips to make it easier to navigate through construction zones:
    • Allow For Extra Travel Time – Allow more time to reach your destination due to detours and lane closures
    • Check 511 - For real-time information dial 511 or visit
    • Stay Alert – Expect anything to occur when entering a work zone
    • Pay Close Attention – Signs and work zone flaggers save lives
    • Turn on Your Headlights – Workers and other motorists must see you
    • Don’t Tailgate – Unexpected stops frequently occur in work zones. Speeding fines double when construction workers are present
    • Don’t Speed – Note the posted speed limits in and around the work zone
    • Keep up With the Traffic Flow – Dedicate your full attention to the roadway and those traveling around you
    • Don’t Change Lanes in the Work Zone – The time saved just isn’t worth it
    • Minimize Distractions – Avoid changing radio stations and using cellular phones while driving in the work zone
    • Expect the Unexpected – Keep an eye out for workers and their equipment
    • Be Patient – Remember the work zone crewmembers are working to improve your future ride.

ITS Questions

What is ITS?

  • ITS stands for Intelligent Transportation Systems. The ITS Program uses advanced electronic technologies to manage the transportation infrastructure efficiently and provides motorists with safer, more reliable roadways. ITS is currently comprised of Closed Circuit Television (CCTV) Cameras, Dynamic Message Signs, and Roadway Detectors. The technology allows traffic managers at the regional Traffic Management Center (TMC) to operate and manage several interrelated services 24/7 that are helping to improve our existing transportation system, such the Road Ranger Service Patrol Program, the new 511 Traveler Information System and the 95 Express.

What are the benefits of ITS?

  • The ITS Program reduces congestion to provide safer and reliable roadway travel conditions. By using this advanced technology to manage the traffic, the ITS Program is maximizing the efficiency and overall capacity of our existing roadway systems. It helps by relieving traffic congestion and reducing the need to build or widen additional roadways. The ITS Program also provides our transportation system with services such as traffic management, incident management and traveler information.

Sound Barrier Questions

What are sound barrier walls? 

  • Sound Barrier walls are an exterior structure designed to block out the noise from any vehicles on the nearby roadway.

How will I know if my home and I qualify to receive a sound barrier wall?

  • Traffic noise studies are conducted when one or more of the following conditions occur:
    • An existing roadway is expanded with through lanes
    • An existing roadway alignment is significantly altered
    • A new roadway is proposed.

The decision on whether or not to provide abatement is made using the criteria described above.  To view if your community falls within the respective areas that will be receiving a sound barrier wall, click on the corresponding segment link below.
