The Arterial under the Route 8 bridge will be down to one lane of traffic from 9 a.m. to 3 p.m. every day through Friday, as crews work on the bridge replacement project.
The bridge is on the Utica-New Hartford line.
There are also long-term lane closures on the bridge, including overnight and on weekends.
Starting last week, the state Department of Transportation closed three ramps on and off the bridge, so workers could start the project.
The ramps include:
- Route 5/8/12 southbound to Route 8 southbound
- Route 8 northbound to Route 5/8/12 southbound
- Route 5/8/12 northbound to Route 840 westbound
