Do I Need E-ZPass for Intercounty Connector? 2025 Update
While E-ZPass is not mandatory to use the Intercounty Connector (ICC), it's highly recommended due to significant cost savings. The ICC operates as Maryland's first all-electronic toll road, meaning you'll pay either through E-ZPass or receive a bill by mail with substantial surcharges.
Key Reality: Without E-ZPass, you'll pay Video Toll Rates (VTR) that are 150% of base toll rates with a minimum $1 and maximum $15 surcharge above base rates. A full-length rush hour trip costs $3.86 with E-ZPass versus $5.79+ without it.
2025 Update: The ICC continues variable pricing with peak rates Monday-Friday 6 AM-9 AM and 4 PM-7 PM. Current toll rates remain at the lowest end of approved ranges, making E-ZPass even more valuable for regular users.
