Officials with the Minnesota Department of Transportation say State Highway 280 will reopen for traffic on Friday morning, so long as the weather cooperates.

Motorists also should be aware of an overnight lane closure on southbound Interstate 35W and westbound Highway 36 near Highway 280 from 10 p.m. Thursday, Aug. 20, to 5 a.m. Friday, Aug. 21. The closures are needed while crews remove road and ramp closure signage ahead of reopening Highway 280.

MnDOT decided to fully close the highway during construction, allowing crews space to complete the reconstruction quickly and safely. 

The highway carries between 50,000 to 60,000 vehicles a day. It’s a major channel for traffic and helps connect Interstate 94 in St. Paul and Highway 36 and Interstate 35W in Roseville.

After the State Fair, MnDOT officials said any additional work needed will only impact the roadway for short-term lane and ramp closures, when needed.

The 280 reconstruction is part of an overall multi-year project estimated to cost $34 million. This stage of the project, Roessler said, is expected to come in within its projected $24 million budget.

In two years, MnDOT will conduct additional work along the corridor to repair bridges over the highway. The left-turn lane from northbound Highway 280 to Broadway Street is also slated to be permanently closed in 2028 in an effort to prevent serious crashes.
