Allentown, PA - March 20th, 2026 - Motorists traveling across the Delaware River bridges connecting the Lehigh Valley are being advised to prepare for potential, albeit minor, travel delays as the Pennsylvania Department of Transportation (PennDOT) and the Delaware River Joint Toll Bridge Commission (DRJTBC) initiate a series of routine safety inspections. The inspections, scheduled to commence next week, are a critical component of maintaining the structural integrity of these vital transportation arteries, but are expected to cause temporary lane restrictions and, in some cases, brief closures.

While PennDOT officials are keen to emphasize that disruptions are anticipated to be minimal, the sheer volume of traffic that utilizes these bridges daily - particularly during peak commuting hours - means even short delays could have a ripple effect across the regional road network. The DRJTBC, responsible for several of the key crossings, has a long-standing commitment to proactive maintenance, and these inspections are a testament to that dedication.

Which Bridges Are Affected?

The advisory currently covers all Delaware River bridges within the Lehigh Valley, including the I-78 bridge (George Van Gorden Memorial Bridge), the Route 22 bridge, and the various local bridges connecting communities like Easton, Phillipsburg, and Allentown. Each bridge will be subject to a thorough assessment of its structural components, including the deck, support beams, cables, and foundations. Specific inspection dates for each bridge have not yet been finalized and will be announced via PennDOT's 511PA service, the DRJTBC website (https://www.drjtbc.org/), and local news outlets.

What Do the Inspections Entail?

The inspection process is far more complex than a simple visual check. Teams of highly trained engineers and specialized inspectors will employ a variety of techniques, including visual inspection, non-destructive testing (NDT), and, in some cases, underwater inspections. NDT methods, such as ultrasonic testing and ground-penetrating radar, allow inspectors to identify potential flaws or weaknesses beneath the surface of the bridge materials without causing damage. Underwater inspections require specialized diving teams and equipment to assess the condition of the bridge foundations.

"These aren't just drive-by inspections," explains Dr. Eleanor Vance, a structural engineering professor at Lehigh University, specializing in bridge infrastructure. "They're incredibly detailed and methodical. Inspectors are looking for everything from minor cracking and corrosion to more significant structural defects. Early detection is key to preventing more serious problems down the road." Dr. Vance added that regular inspections allow for timely repairs, extending the lifespan of the bridges and preventing costly and disruptive emergency repairs.

Why Are These Inspections Necessary? The Delaware River bridges are essential for the economic vitality of the Lehigh Valley, facilitating the movement of goods, services, and people. The region has seen significant population and economic growth in recent years, increasing the strain on existing infrastructure. The bridges are subjected to constant wear and tear from heavy traffic, exposure to the elements, and the natural process of material degradation. Routine inspections are mandated by both state and federal regulations to ensure public safety and prevent catastrophic failures.

How Can Motorists Prepare?

Motorists are strongly encouraged to check traffic conditions before embarking on their journeys. The 511PA service (available online at https://www.511pa.org/ or via the 511PA app) provides real-time traffic updates, including information on bridge closures and lane restrictions. The DRJTBC website also offers detailed information on bridge conditions and planned maintenance activities.

Drivers should allow extra travel time, especially during peak commuting hours. Consider alternate routes if possible, and be prepared for potential delays. Staying informed and exercising patience will help minimize inconvenience.

The PennDOT and DRJTBC are committed to providing accurate and timely information to the public. Further details regarding specific bridge closures and inspection timelines will be released as they become available. The agencies emphasize that the short-term inconvenience of these inspections is a small price to pay for the long-term safety and reliability of the region's vital transportation infrastructure.
