Interstate 94 will get narrow in key stretches across the Twin Cities this weekend, the Minnesota Department of Transportation’s road hassles map shows.

Here’s a look at some of the detail, via MnDOT.

I-94, St. Paul to Maplewood. Starting at 8 p.m. Friday through 5 a.m. Saturday, eastbound I-94 from Mounds Boulevard to Century Avenue will have alternating single lane closures. Drivers should expect lane restrictions in both directions, traffic delays and temporary exit/entrance ramp closures as project work continues between St. Paul and Maplewood. There are several ramp closures and detours.

I-94 Minneapolis to Brooklyn Center. From 8 p.m. Friday until 5 a.m. Monday, southbound Minnesota Highway 252 will be reduced to a single lane between Interstate 694 to I-94. Also the ramp from southbound 252 to eastbound/westbound I-694, Minnesota Highway 100 and westbound I-94 is closed from 10 p.m. Friday to 7 a.m. Saturday. There are several other ramp closures.

Beginning Monday on that stretch:

• Southbound Highway 252 to eastbound I-94 will be closed for bridge work through mid-July.

•Westbound I-94 to westbound I-394 will be reduced to a single lane. The Interstate 394 HOV reversible lane will be used for all motorists traveling from westbound I-94 to westbound I-394 or to Minnesota Highway 100. This will last until June 12.

•The ramps from Lyndale Avenue to westbound I-394 and from eastbound I-94 to westbound I-394 will be closed through mid-to-late June.
