Delaware Toll Hikes and New Billing Rules Take Effect Aug. 15, 2025

Drivers using Delaware’s major highways are seeing new toll rates and updated billing procedures as of mid‑August. According to the Delaware Department of Transportation (DelDOT), toll rates on Route 1, Interstate 95 and U.S. 301 increased at 12:00 a.m. on Aug. 15, 2025. For example, a trip along the full length of Route 1 now costs $5.00 with an E‑ZPass and $6.00 if paying by mail, up from $4.00 and $5.00 previously. Rates for I‑95 and U.S. 301 have also risen by similar margins. The agency said the adjustments will fund capital improvements and maintenance projects along these heavily travelled corridors.

In addition to higher rates, DelDOT is changing how drivers without an E‑ZPass account are billed. Motorists who pass through an E‑ZPass lane without a transponder will no longer receive a violation notice; instead they will automatically be mailed an invoice for the toll amount due, which must be paid within 30 days to avoid penalties. This policy is designed to reduce confusion and streamline collections. DelDOT encourages frequent travellers to obtain an E‑ZPass, noting that transponders remain free to new customers who sign up by Aug. 31 and that E‑ZPass users pay the lowest toll rates. The agency’s release reminds drivers to keep their account information and vehicle registration up to date to ensure proper billing.

To help customers budget for these changes, DelDOT has launched an online toll calculator that allows drivers to estimate toll costs before they travel. The tool is available on the state’s website and includes all toll facilities in Delaware. Because the rate hike may add significant costs for commuters and vacationers, travellers should check the calculator when planning routes and consider alternate roads if cost is a concern. With the new invoice system and free transponders through Aug. 31, now is a good time for drivers to transition to E‑ZPass and avoid surprise bills.
