GUILDERLAND — Winn Construction began work on March 17 to replace the bridge on State Route 146 over the Normans Kill. 

The bridge is located between Tawasentha Park and Ostrander Road.

The state Department of Transportation project is anticipated to take two years to complete. 

A temporary bridge with two lanes of traffic will be installed and all properties in the area will remain accessible to residents and emergency responders, according to a notice from the town.
