Motorists in the south metro should plan on delays and detours this weekend as the Minnesota Department of Transportation closes lanes on Interstate 494 between Inver Grove Heights and Sunfish Lake.

The biggest change will be on eastbound I-494, which will go down to one lane between Delaware Avenue and Hwy. 52 from 9 a.m. Friday to 5 p.m. Saturday. Concrete repair on Hwy. 169 near Canterbury Road in Shakopee also could spawn delays as it has during this week’s rush hours.

Metro Transit rolls out new schedules Saturday on a number of bus routes. Local routes will follow Saturday schedules with a few modifications, and commuter express routes will run at reduced levels. Trips scheduled after 11 p.m. and before 4:30 a.m. will be restored on the A and C lines and a number of other routes. Riders should check metrotransit.org for updated schedules, said spokesman Howie Padilla.
