A portion of a major north-south route through Washington County will be closed for the summer for construction work.
County transportation officials will widen Manning Avenue in the Stillwater area, from two lanes to four lanes. To do that, they plan to close about a mile stretch that runs from 62nd Street N. to 75th Street N. (also known as County Road 12).
Traffic will be detoured on Lake Elmo Avenue (also known as County Road 17) and 75th Street.
The section will be closed, starting in early June. Officials are hoping to reopen it by Oct. 15.
Only residents living along the road will be able to use it during construction.
In addition, County Road 12, located west of Manning Avenue, will be closed for roughly two weeks in early June, at the beginning of the project.
An open house to discuss the project will be held from 4 to 7 p.m. Thursday at the Washington County Government Center, room 560, 14949 62nd St. N. in Stillwater.
Joe Lux, senior transportation planner for the county, said the road was built in 1961 and planners at the time envisioned it could support about 3,000 cars a day over the next 20 years.
