MADISON, Wis. (AP) — Transportation officials plan to replace the license plates that celebrate the state's 150th anniversary because the red lettering has faded. The Sesquicentennial plates were first issued in 1996. The state Department of Transportation says the special plates will be replaced with regular license plates. About 160,000 Sesquicentennial plates are still on the road. The DOT says it will also replace 135,000 regular red-lettered plates with standard black-lettered plates. The DOT hopes to complete the replacement process by September 2014.
