Residents and property owners in two University of Minnesota neighborhoods have voted down proposed sound walls along Interstate 35W.

The four walls faced significant opposition from Marcy-Holmes and Southeast Como residents, who said they were unnecessary blights on their neighborhoods.

The 30-day voting process began July 19 for Southeast Como and July 24 for Marcy-Holmes.

A $13 million project to renovate the highway and add a northbound lane, scheduled to begin next year, won’t be affected by the vote.

“This was a huge effort that brought our neighborhood together,” Marcy-Holmes Neighborhood Association Executive Director Melissa Bean said Wednesday in an e-mail.

The neighborhood association had urged residents to vote against the walls.
