Do you find mile-based exit numbering easier to navigate than sequential exit numbers?

The New York State Department of Transportation has launched a $1.1 million project to convert exit numbers on Interstate 88 to a mile-based system. This update covers the route from Port Crane to the I-90 interchange in Rotterdam to improve driver navigation.

Why it matters

Updating to a mile-based system aligns I-88 with standard practices used on most U.S. interstates and I-81. The change is intended to streamline travel and assist with emergency response across the six counties the highway spans.

The renovation project spans the entirety of the 117-mile Interstate 88 corridor across six New York counties. It is budgeted at $1.1 million, with crews currently prioritizing shoulder work for sign installation.

The players

New York State Department of Transportation

This state agency is responsible for the design, construction, and maintenance of New York's highway and bridge infrastructure.

The details

Existing signage will temporarily feature both the old and new exit numbers to assist drivers during the transition. Exits 1 and 2 will remain unchanged as part of the system overhaul.

1960s: Interstate 88 began service as an east-west corridor.
October 2026: The Department of Transportation initiated the signage project.

Roadmap

This transition aligns New York highway infrastructure with the Manual on Uniform Traffic Control Devices (MUTCD) standards used across the United States. Adopting mile-based markers reduces confusion for long-distance drivers by creating a predictable, universal system.

Drivers using Interstate 88 should prepare for potential shoulder activity as crews perform sign installations during daytime hours. Commuters should check local transit alerts for any temporary traffic adjustments during the rollout of the new exit numbers.

The takeaway

Drivers navigating I-88 should anticipate updated signage as the state moves toward a mile-marker system. Pay close attention to temporary signs that display both the legacy and new exit numbers until the transition is complete.
