MAJOR STRADDLE BENT REBAR CAGE INSTALLATION COMPLETED

OCTOBER 2026

On Sunday, October 11, crews completed the installation of a massive reinforcing steel cage for a new straddle bent along S.R. 836. Weighing about 127,000 pounds and measuring 130 feet long, the cage was carefully lifted by cranes and lowered into the formwork.

To complete this complex operation safely, crews brought in about 30 truckloads of material to build and level a stable working pad on the roadway for the cranes. The successful installation marks another important milestone in constructing the new double-decked S.R. 836 roadway.

Check out the video for a closer look at this impressive operation.

CONCRETE POUR ADVANCES THE NEW S.R. 836 DOUBLE-DECKED ROADWAY WEST OF THE MIAMI RIVER

OCTOBER 2026

The video shows crews completing a major concrete pour on October 3, for the new double-decked S.R. 836 roadway just west of the Miami River. The operation used one concrete pump and approximately 60 concrete trucks to place 590 cubic yards of concrete — roughly 2.4 million pounds — as crews continue advancing construction of the new elevated roadway.

CONCRETE POUR FOR THE WESTBOUND I-395 SIGNATURE BRIDGE SUPERSTRUCTURE

SEPTEMBER 2026

Construction continues to advance on the westbound I-395 Signature Bridge superstructure, with crews installing reinforcing steel, formwork, and post-tensioning ducts and placing concrete for the massive box-girder deck. The post-tensioning system will add strength as the deck is constructed and work with the bridge’s arches and stay cables to support the completed superstructure. Recent concrete operations have included pours for the deck, webs, and diaphragms that make up the box girder. The video shows one of the largest concrete pumps in the country in action during a recent pour on the westbound Signature Bridge superstructure. As work progresses, these sections are coming together to form the new westbound I-395 roadway.

SIGNATURE BRIDGE CONSTRUCTION FROM ABOVE

SEPTEMBER 2026

This drone video offers an aerial view of ongoing construction on the I-395 Signature Bridge. Arches 1, 2, 4, and 5 are closed, while crews continue work on the first of three cast-in-place structural elements for each of the two remaining arches, 3 and 6. Other work shown includes the installation of falsework, formwork, and reinforcing steel, along with concrete pours for the westbound Signature Bridge superstructure, which will ultimately be supported by the arches and stay cables.

MAJOR MILESTONE ACHIEVED AT SIGNATURE BRIDGE ARCH #6

JULY 2026

The project team recently reached another major milestone with the successful completion of the foundation pour for Signature Bridge Arch #6, located adjacent to the Phillip and Patricia Frost Museum of Science. This was the second-largest concrete and most complex foundation pour of the entire project and represents a significant step toward construction of one of the two remaining arches.

The foundation measures 120 feet long, 50 feet wide, and 16 feet deep, and required approximately 3,672 cubic yards of concrete, delivered by 408 concrete trucks, placed by four concrete pumps (with a fifth on standby). To ensure the concrete cures properly, crews installed an advanced cooling system consisting of more than 30,000 feet of tubing circulating chilled water from a large industrial chiller, with a backup chiller on site for redundancy.

STRADDLE BENT FORMWORK ERECTED

JULY 2026

The time lapse video shows the successful erection of formwork for the final straddle bent support structure, which will span the full width of eastbound S.R. 836. The formwork measures 134 feet long and weighs approximately 266,000 pounds. The operation required two heavy-lift cranes and the delivery of approximately 26 truckloads of limerock to construct a temporary crane pad. Once the work was complete, the material was removed, the roadway was cleaned, and all lanes were reopened to traffic. The next step in constructing the straddle bent will involve assembling and installing a reinforcing steel cage in preparation for the concrete pour.

ANOTHER MILESTONE ACHIEVED – COMPLETION OF THE INSTALLATION OF ALL PRECAST ARCH # 4 SEGMENTS

MAY 2026

On Friday, May 15, the project team completed the installation of all 65 precast arch segments for Arch #4 that soars 252 feet over Biscayne Boulevard. Each segment is unique and weighs approximately 90 tons.

INSTALLATION OF 90-TON PRECAST ARCH SEGMENT

AUGUST 2025

Crews carefully erect one of 65 precast arch segments that will form one of the six soaring arches of the I-395 Signature Bridge, a new Miami landmark in the making. A total of 345 precast arch segments will be used to complete all six arches.
