Two smoking shelters are being put back into the grounds of the Great Western Hospital to stop staff using a busy road to avoid a smoking exclusion zone.
Bosses banned anyone from lighting up within the Swindon hospital's boundary last year to encourage smokers to give up and to protect non-smokers.
But fears were raised after staff began walking to a nearby road to smoke.
A hospital spokesman said the new shelters would be kept out of the sight of visitors and patients.
He said they would be located near to the staff car park.
