A ballot measure to close a 2-mile stretch of San Francisco’s Great Highway passed with 54% of the vote in returns released Saturday afternoon. The controversial proposal, known as Proposition K, will ban vehicles on the city’s westernmost coastal boulevard between Lincoln Way and Sloat Boulevard.

San Francisco's Proposition K, the measure to determine if part of the Great Highway would be closed to vehicle traffic alongside Ocean Beach, has passed.

A 2-mile section of the Upper Great Highway will be permanently closed to private vehicles after San Francisco voters approved local Measure K. As of Saturday afternoon, approval of the measure was leading by a margin of more than 8 percentage points, or 54.06% to 45.94%, according to unofficial results from Tuesday's general election.
