Placement

WELCOME TO TEXAS (I-2T) signs should be installed as close to the state line as practical.
Interstate Routes.
On interstate routes, districts should make sure the welcome sign does not conflict with existing signing and submit schematics showing the proposed location to the TxDOT Traffic Operations Division (TRF) for review.
U.S., State, and FM Highways.
On U.S., state, and FM highways, the welcome sign should be located within 500 feet of the border.
