Transportation; requiring installation of business access signage during certain projects; stating requirements for signage; effective date.

HB 3664 requires contractors working on Oklahoma Department of Transportation (DOT) projects that block normal business access to install and maintain clear directional signage for affected businesses. The bill mandates contractors submit a signage plan for DOT approval before construction begins, specifying location, size, and design to comply with traffic control standards. Contractors must keep signage visible and accurate during construction and remove it promptly after project completion, with non-compliance risking $10,000 daily penalties. This law applies to all DOT-funded transportation projects affecting business access and takes effect November 1, 2026.
