Big changes are coming to Mobile’s skyline, but first, it’s time for groundwork—literally. The Mobile River Bridge and Bayway project has officially entered the steel pile load testing phase.
This early step in the construction process focuses on the most important thing a bridge needs: solid support. Crews are testing 72-inch steel pipe piles—giant tubes that will eventually hold up the new bridge’s main pylons. Before any concrete goes up or road decks get poured, these piles need to prove they can handle the job.
Testing for Strength and Safety
The testing isn’t just about strength—it’s about getting things right from the start. The Steel Pile Load Test Program helps engineers figure out exactly how much weight the piles can handle. It also gives them real-time data to fine-tune the final bridge design.
Crews are currently at work in two spots:
- West Pylon Site – Near the intersection of Eslava Street and Old Water Street
- East Pylon Site – Near Dunlap Drive, just west of the Austal facility
At each site, workers are leveling the ground, setting up heavy machinery, and installing piles into the soil. Once the piles are in place, they’ll apply enormous amounts of force to simulate what the bridge will experience over time. Think of it like a stress test—only on a massive scale.
Who’s Behind the Work?
The job is being handled by Kiewit Massman Traylor (KMT), a team of contractors working together to design and build the bridge. KMT has experience with major infrastructure projects, so this isn’t their first time dealing with giant steel piles or complex foundations.
The testing phase started in mid-June and is expected to run through August. Crews are on-site Monday through Friday from 6 a.m. to 6 p.m. Each location has its own timeline depending on weather, soil conditions, and equipment needs.
Traffic Impact? Minimal.
For anyone wondering about traffic delays, here’s some good news: the testing is happening off the main roads. The sites are set back far enough that drivers won’t feel much of a pinch.
Crews are doing their work quietly—well, as quietly as heavy equipment allows—and traffic is flowing as usual. No detours, no extra orange cones, and no sudden stops.
Of course, anyone passing by might spot cranes, piles of steel, and large rigs moving equipment into place. It’s all part of the process as the groundwork moves ahead.
Building Toward the Future
Once the testing wraps up, engineers will take the data and finalize the bridge design. That’s when the real construction begins—when pylons rise, beams get set, and the new Mobile River Bridge starts to take shape.
This project represents a major leap forward for the region’s transportation system. It’s about smoother drives, safer crossings, and new connections. But before all that can happen, the foundation has to be rock solid.
By checking the piles now, the team is making sure the bridge will stand strong for decades to come.
For now, the sounds of pile testing echo along the riverfront. Soon, those sounds will give way to the rhythm of full-scale construction—and eventually, to the hum of cars, trucks, and travelers crossing the bay on a brand-new bridge.
