Rainbow flags are flying high over a Mississippi River crossing in Minnesota's Capital city to welcome the expected legalization of same-sex marriage in Minnesota.

"Today, we line the Freedom to Marry Bridge with pride flags to show the importance of this legislation to the City of Saint Paul, the families that live here, and to those who have been waiting for this day for many years," said St. Paul Mayor Chris Coleman.

The city temporarily renamed the Wabasha Bridge, which crosses the Mississippi River in St. Paul, to celebrate.

The Minnesota Senate is expected to give final approval to the legalization measure Monday afternoon and Gov. Mark Dayton is expected to sign it on Tuesday.
