The bill, H.B. No. 2944, mandates the Texas Transportation Commission to designate any portion of State Highway 87 that is not already classified as a hurricane evacuation route as such, effective as soon as possible after the bill's enactment. This designation aims to enhance the state's preparedness and response capabilities during hurricane events, ensuring that critical evacuation routes are clearly established.

The bill stipulates that it will take effect immediately if it secures a two-thirds majority vote from all elected members in both houses of the legislature. If the necessary vote is not achieved, the bill will take effect on September 1, 2025.
