The project team says technology played a central role in the $68.3-million plan to construct five dual bridges within an 11-mile section of the planned 1,500-mile Continental 1 international trade corridor, connecting Canada with Florida.

Converting the functionally obsolete cloverleaf interchange connecting I-70 and U.S. Route 19 into Pennsylvania’s first diverging diamond interchange required a traffic control plan to minimize disruptions to the tens of thousands of motorists who travel through the area daily.

The project called for a major traffic change, replacing a congested signal-controlled intersection in a primary commercial corridor with a three-lane roundabout.

Replacing the concrete open spandrel arch bridge that had served as Pittsburgh’s eastern gateway for nearly a century was more challenging than the original construction.

Located 25 miles north of Fort Worth in Haslet, this intermodal railroad project involved track construction, pavement, ditch grading and placement of culverts.

Using innovative techniques and careful planning and sequencing, the project team replaced the BNSF railway bridge over busy I-235 with minimal traffic disruptions and within two-thirds of the contract time.

Utah State Route 132 is one of Sanpete County’s busiest roads.
