There's confusion among some commuters along the Hutchinson River Parkway after exit signs switched up right before their eyes.

Within the past few weeks, the State Department of Transportation changed the numbers on the exit signs along the parkway.

The DOT says it is installing new retro-reflective, mileage-based exit signs along the parkway from the Bruckner Interchange in the Bronx all the way to the Connecticut state line.

Along with the upgrades and replacements to these exit signs, they say they're also doing this to directional signs along the ramps.

Some residents say not enough notice was given, and it's causing confusing commutes.

"I think that it's a big issue for the public, I mean if you're traveling and you're using your GPS like you did this morning, and you didn't know where you were going, it could cause an accident and quite frankly it should be addressed, says Carrie Giammarino of Scarsdale.

The areas the DOT transitioned exit signs to a mile-based exit numbering system includes the Hutchinson River Parkway, the Taconic State Parkway and Interstate 84.

The State DOT also says that a primary consideration is to keep a consistent exit numbering system to avoid confusing drivers, but some residents say that is not working.

Giammarino tells News 12 she missed her exit, which is now Exit 9 but was previously Exit 17, while driving on the Hutchinson River Parkway last week. She adds that she wasn’t alone in this in that nearly a half-dozen other cars after her were also missing the exit and even tried to back up onto the parkway.

Commuters are advised to be aware of the change in signs and to double-check their GPS as they move along the parkway.
