Motorists will encounter single-lane traffic on Interstate 35 underneath the Lake Avenue Bridge in Duluth through Wednesday.

Minnesota Department of Transportation is reducing both northbound and southbound roads to single lanes so crews can do a routine inspection of the box girders on the bridge, according to a news release from MnDOT.

The single-lane closures will take place between 8 a.m. and 3 p.m. through Christmas Day.
