So you think Super Bowl detours were bad? And last summer's Lowry Hill Tunnel project? Fasten your seat belts.
This week's ramp closures and detours are just a foretaste of what's coming in mid-June. That's when the Minnesota Department of Transportation will shut down the main ramp leading from northbound Interstate 35W into downtown Minneapolis — for four months.
MnDOT, city officials and many downtown employers are bracing for epic traffic jams and urging commuters to take transit or work at home — and even dangling huge parking discounts for carpools.
The I-94/I-35W interchange is being rebuilt as part of a $239 million makeover of I-35W between downtown and 43rd Street. But that is just one of four work zones that I-35W drivers will encounter this summer. Overlapping projects with lane closures of their own will be underway simultaneously in Burnsville and Roseville and just past the I-35W/35E split in Forest Lake.
"We want to keep as many people off I-35W as possible," said MnDOT spokesman Dave Aeikens.
By far the biggest pinch point will be downtown, where MnDOT will slim down I-35W from 10 travel lanes to five and shut the main ramp, pushing 42,500 drivers daily to the one remaining access point: the winding ramp at 3rd Street and Washington Avenue behind U.S. Bank Stadium.
The flyover bridge from northbound I-35W to westbound I-94 will be out of commission. So will the outbound ramps to southbound I-35W at 12th Street and 4th Avenue S., leaving 4th Street and Washington Avenue as the two exits.
"We realize these are big impacts," said MnDOT spokesman Aaron Tag. "It's a big project in an urban setting and it's hard to keep traffic moving when you rebuild this infrastructure."
