Ongoing work on the Wellwood Avenue Bridge in North Lindenhurst will cause nighttime lane closings in both directions of Sunrise Highway beginning Wednesday, the state Department of Transportation said.

One or two eastbound and/or westbound travel lanes of Sunrise Highway near the bridge will be closed, weather permitting, between 10 p.m. and 6 a.m. on weekdays for about one month, DOT said.

Those closures are in addition to the intermittent, off-peak, daytime closures of Wellwood Avenue and Sunrise Highway that are already in effect weekdays between 10 a.m. and 3 p.m.

At least one travel lane in each direction of Wellwood Avenue and Sunrise Highway will remain open to traffic, DOT said.
