The ramp from Mesaba Avenue to southbound I-35 will close at 9 p.m. Thursday to allow crews to safely remove the concrete bridge deck that spans over the ramp, according to the Minnesota Department of Transportation.
Work will continue throughout the night and the ramp will reopen at 5 a.m. Friday.
The detour will take motorists west onto Superior Street, then onto lower Michigan Street, then west to 27th Avenue West where they can take the I-35 southbound ramp.
