A bridge rehabilitation project in Danbury has started.  The Triangle Street bridge is located near the intersection with Lee Mac Avenue and over the Still River.  The work started yesterday.  The width of the traffic lanes, one in each direction, over the bridge has been reduced to two ten-foot wide lanes.  The speed limit is now 20 miles per hour.  Delays should be expected and drivers are recommended to avoid using the bridge.  Detour signs are set up to direct drivers to use alternate routes.
