Drivers can expect significant traffic delays during rush hour Tuesday as entrance ramps onto eastbound President George Bush Turnpike are closed to make way for a fallen officer's funeral procession. The North Texas Tollway Authority said in a news release drivers can expect delays to last an hour or more. An NTTA spokesperson said in an email drivers should monitor traffic reports and avoid traveling between 4-6 p.m. Traffic control will only affect the eastbound lanes, the spokesperson said. The procession for fallen Richardson Police Officer David Sherrard is scheduled to span from US 75 to Miller Road along PGBT.
