There won’t be any full closures of Twin Cities freeways this weekend, and that’s a good thing.

Drivers will want to use Interstates 94, 35E and 35W to get around the Twin Cities Marathon, which on Sunday will shut down several downtown Minneapolis streets, plus roads near the State Capitol in St. Paul and several others in between the start and finish lines.

The racecourse that largely follows parkways and Summit Avenue includes closures where runners cross thoroughfares in both cities. There will be limited places for motorists to cross the course.

For drivers, the best option is to head for the freeways or major routes, such as Hiawatha Avenue. Most roads will open by midmorning, but others will remain closed until the race ends around 2:30 p.m.

A host of bus routes will also be detoured during the race, so check metrotransit.org for affected routes.

Here are some other places drivers could find delays due to ongoing construction:
