Fernbrook road work Work on Fernbrook Lane south of Hwy. 55 in Plymouth will reroute traffic Saturday and Sunday. The intersection of Fernbrook Lane and 27th Avenue N. will be closed for underground utility work.

The work is part of the larger Fernbrook Lane reconstruction project, which runs from 27th Avenue N. to 34th Avenue N. It's "the first significant improvement to the road since 1978, when the road was widened from two lanes to four," the city says. It should improve traffic flow, enhance safety and protect water quality, according to City Engineer Bob Moberg.

Call 763-509-5500 for more information.
