An audit by state Comptroller Tom DiNapoli identifies more than $12 million in cost overruns at new I Love NY rest areas and welcome centers.

The audit finds the state Department of Transportation failed to properly plan for construction of the facilities.

In one case, a sewer system was initially left off the plans for a Long Island rest stop, leading to $7 million in cost overruns.

The DOT disputes the findings, in part because one of the auditors is accused of placing a GPS tracker on a DOT employee's car while the review was underway.  

He now faces stalking charges and was removed from the audit before leaving the comptroller's office.

DiNapoli's office said the DOT is using the case to discredit the entire audit.
