The restriction is part of a project to modify the intersection because of left-turn sight distance restrictions for turning traffic. The town is looking to improve sight visibility in all four directions at Gilbert and Ray roads.
The intersection is one of 10 scheduled to be modified.
Demolition of the islands on the north and south legs of the intersection at Gilbert and Ray roads has started, and streetlights will be relocated.
The $1.3 million project is expected to be completed in July. The Maricopa Association of Governments is funding the project.
