NORTH HERO - GRAND ISLE
DRAWBRIDGE CONSTRUCTION UPDATE - 4/28/2022

Traffic Impact

US Route 2 at the temporary drawbridge is open to two lanes of traffic. The contractor is working during the day from 6:30 AM to 5:30 PM, Monday through Saturday. They are also working a night shift from 5:30 PM to 4:00 AM, Monday through Friday, and 3:00 PM to midnight on Saturdays. Night work is planned to continue through May 15th.

 

The temporary bridge has a speed limit of 25 mph. There are tight curves approaching the temporary bridge, and trucks are advised to reduce speed to 15 mph. Bicycles should use caution while crossing the bridge.

 

The work zone speed limit is enforced, and individuals have been ticketed for excessive speeding. Obeying the speed limit is extremely important for everyone's safety.

Notice to Mariners

The navigational channel is closed from December 6, 2021 through May 14, 2022. The drawbridge will resume seasonal openings on May 15, 2022. At that time, we will be keeping one leaf of the draw span closed while construction progresses, and lifting the other to allow vessels to pass through the channel. This arrangement will provide 40 feet of horizontal clearance and unlimited vertical clearance. Additional measures such as signage, a second bridge tender, law enforcement, and barges will be in place.

Construction Activities

On the west side of the existing bridge, the contractor is continuing to bolt the toe girder diaphragm connections. They also installed the bascule walkway steel that provides access to the span locks as well as the exterior bascule walkway steel. Next week, they will continue bolting the bascule steel walkway and diaphragm bolting. They will also set the taillocks which apply a mechanical load to the counterweight. The counterweight assists with securing the bridge when it is in the down position.

 

On the east side of the existing bridge, the contractor is pouring concrete for the counterweight. They also removed the generator pad formwork. Next week, they will continue bolting bascule diaphragms to the toe girders.

PROJECTED COMPLETION: Winter 2023
