The new two-mile extension of the Lockport Expressway and a one-mile widened stretch of Millersport Highway will open with a ceremony at 10 a.m. Dec. 21, according to the state Department of Transportation.
Daniel Hearn, engineer-in-charge, said the $20 million project will open about 10 months ahead of schedule.
"We had good weather and we had a good contractor -- Cold Spring Construction," he said.
The new portion of the I-990 extends from the current terminus at North French Road to New Road, with Millersport widened for another mile. Work has been under way for about 18 months.
