OKLAHOMA CITY (AP) - Oklahoma City voters have approved the third Metropolitan Area Projects proposal.

With all 271 precincts reporting Tuesday, a little more than 54 percent of voters approved the extension of a one-cent sales tax. That tax in recent years has helped transform downtown and provided a boost for local schools.

Under the $777 million MAPS 3 proposal, city leaders have promised a new convention center and 70-acre park, a downtown streetcar system, bicycle trails, sidewalks, senior centers and improvements along the Oklahoma River.

Proponents of MAPS 3 said it would sustain what they call unprecedented progress in the state's largest city.

Opponents had argued a recession is not the time to extend a sales tax.
