There’s the potential for some traffic snarls this weekend around the Sodo stadiums, the Alaskan Way Viaduct and on Interstate 5, so be prepared and plan ahead.

Here’s a list of what’s happening:

The viaduct is closed from 6 a.m. to 5 p.m. Saturday and from 6 a.m. to noon Sunday, for its routine semiannual inspection.

The onramp from the West Seattle Bridge route (elevated Spokane Street) to southbound I-5 will close from 10 p.m. Friday until 5 a.m. Monday, to repair expansion joints between the elevated bridge spans.
