I-280/Route 21 Interchange Improvements Project Recognized by ENR New York as 2019 Best Highway/Bridge Project

Michael Baker's I-280/Route 21 Interchange Improvements project in Newark, New Jersey, has been recognized as ENR New York’s Best Highway/Bridge Project of 2019.

With average daily traffic (ADT) of more than 80,000 vehicles, I-280 is a major east-west corridor that connects the NJ Turnpike with the Garden State Parkway through Newark, New Jersey’s largest city. The $95M complex, urban interchange reconstruction addressed long-standing concerns regarding the safety and efficiency of the interchange, which included correcting geometric deficiencies, improving safety along the corridor, providing missing interchange movements between an interstate highway and a principal arterial, optimizing the existing Route 280 throughput without adding through lane capacity, and improving the condition and reliability of the corridor.

The project team replaced and constructed four new bridges, rehabilitated two bridges within the interchange, widened and shifted the Interstate to add shoulders, constructed three missing moves, and eliminated two direct Interstate ramps onto local roads to alleviate the poor condition and geometric concerns associated with the existing ramps and mainline structures.
