COLONIE & HALFMOON — One or two lanes on the Northway's Twin Bridges will be closed overnight for the next month, as a contractor installs a new, specialized concrete surface on the bridge, the state Department of Transportation said.
One lane will be closed about 8 p.m. each weeknight, after rush hour, and a second lane will be closed at 10 p.m., DOT spokesman Bryan Viggiani said. One of the closed lanes will re-open each morning by about 6 a.m., in time to accommodate the morning commute, and all three lanes are supposed to be open each day by 8 a.m., when heavy commuting volume starts.
At this point, DOT isn't recommending detours to avoid delays.
"The volumes (of traffic) at night, even this time of year, are low enough that there shouldn't be any impact," Viggiani said.
The work will be done in the northbound lanes, weather permitting, through the middle of next week, and will then shift to the southbound bridge starting Sept. 7.
The work is being done under a $3.35 million contract awarded to American Civil Constructors West Coast of Benicia, California. Viggiani said the California company submitted the lowest bid on the project, which involves installing a specialized concrete surface — called polyester polymer concrete — on the bridge.
Viggiani said the material is supposed to be more durable and flexible than conventional concrete, and the state has used it on other high-volume bridges.
Viggiani said no weekend work is planned, unless the contractor falls behind due to weather problems. The work is supposed to be finished by Sept. 30. There will be no work over the coming Labor Day three-day weekend.
The bridges — formally known as the Thaddeus Kosciuszko Bridge — carry the Northway across the Mohawk River between Albany and Saratoga counties.
